Abstract.

Intent: basing on the instrumental survey measurement, to determine rate of tensile strain displacements in the rock mass.

Results. Results of the instrumental surveying monitoring of the rock mass and surface displacements were generalized, and on their basis, rate of deformation was determined. Interdependence between the rate of the deformation displacements, rate of the mine face drivage, depth of the mining operations and height of zone with the rock foliation was specified.

Scientific novelty. It is for the first time when, on the basis of instrumental observations, rate of the tensile strain displacement in the rocks with varying degrees of lithification was defined. Height of zone with the rock foliation in the undermined mass was determined on the basis of the established interdependence between the rate of deformations.

Practical significance. The obtained data on the rate of deformation displacement in the undermined rock mass makes possible to control rock pressure and to improve efficiency of mining operations and their safety.

Keywords: underground mining operations, rate of deformation, dynamic trough, surveying monitoring of displacement.

(State HEI “NMU”)

Abstract.

The purpose of this paper is a simultaneous analysis of the results of monitoring over the earth's surface subsidence and undermined rock mass movement. The solution of this task is based on the results of in-situ observations over the earth's surface subsidence and rock mass movement.

The paper analyses movement and deformation of a surface observation station and an observation borehole extensometer that were set up over the longwall panels of Western Donbass mines. A research of the behavior of the rock mass and the earth's surface was performed in conditions of the working longwall face. In the result of the research the qualitative and quantitative objective laws of slightly metamorphized rock mass movement are established.

The established laws allow for the correction of existing scheme of rock movement and for the changing of existing approach to analysis of earth's surface horizontal movement and strain.

Keywords: subsidence, strain, rock, undermining, benchmark, borehole extensometer.

Abstract.

Initial state of zone with tectonic displacement in geomechanical space of the coal-rock mass was considered, and energetic potential of this area and volume of stored methane were specified. The specified regularities of potential strain energy changing help evaluating  potential energy conformers of the molecular structure of coal, which cause the structure deformation in the area with bearing pressure.

The article represents a model of the coal fractured-and-porous structure in the displaced area, which  consists of fragments of different scale level in the hierarchical structure of the coal.

Modeling of filtering process in the coal seam is based on a concept that a coal seam is a structurally heterogeneous system represented in the form of combinations of several sections, each of which is described by average values of porosity and gas permeability with the help of the K.S. Basniev method. Such approach makes possible to apply the Y.P. Zheltov filtering equation to any combination of the coal sections.  A problem of methane desorption from the core of displaced zone in the coal seam was reduced to the problem of total methane diffusion from the coal fragments, which were separated by the coal broken structure. With a single source, desorption is described by diffusion equation in spherical coordinates. In order to specify the activation energy and diffusion coefficient, the Pace-Deytiner model was used with taking into account the following key parameters: constants, which described deformation of the coal broken structure; the Lennard-Jones potential, which characterized energetic interdependence between the coal structure and methane molecules; diameter of methane molecule and length of its free diffusion jump; and temperature of the coal seam.

Keywords: coal seam, filtering, free methane, adsorbed methane, desorption, diffusion.

Abstract.

Subject of the research was carboxylic sandstones in the Krasnoarmeysk region of Donetsk coal basin. Objective of the work was to study and analyze conditions of formation and transformation of sandstones, which contain coal of different stages of coalification. The study was carried out on standard microsections with the help of optical microscopy. The microsections were taken from the sandstone samples chosen in the faces of coal mines or from the core of exploration wells. Basing on the results, it is stated that structure of sandstone of diagenesis and early katagenesis stages was formed in the process of its formation (sedimentogenesis). Structure of sedimentary rocks of the katagenesis middle substage is significantly changed under the influence of high pressure and temperature. At this substage, microstrain is accumulated in the largest sandstone grains, which are divided into smaller fragments. This process significantly worsens collecting properties of the sandstones as they are transformed into dense collector. The obtained results can be used by oil and gas industry for predicting the sandstone collecting properties, and by coal industry for forecasting outburst of sandstones, gas concentrations and formation of blowers. Thus, regularities of structural transformations of sandstone of the katagenesis middle substage are established, and they allow to assess a degree of sand collector transformation into the dense collector.

Key words: Structural transformations, sandstones, substage of katagenesis.

THE MINERAL KATAGENESIS AND DEFORMATIONS AS THE KEY FACTORS IMPACTING ON THE ROCK GEOMECHANICAL PROPERTIES

UDK 552.08:622.02:539.2/.8

Mametova L.F. Ph.D. (Geol.), Senior Researcher

Abstract.

The research results of mineral transformation in the rocks of Donbass coalfields are presented in the article. Sandstones samples of medium carbon from the G-grade coal spreading areas in peripheral areas of the region were studied. In the course of optical and other researches, difference between intensity of geochemical transformations and microstrain of essential minerals in the western and eastern sediments was determined. Geochemical and structural changes of the sandstone minerals are similar in these areas, but there are a number of signs indicating an impulsive nature of tectonic movements and different stress intensity, which is higher in the east and lower in the southwest. The first sing is an established differentiation between microstrain types spreading in the rockforming minerals. Combinations of the quartz elastic deformations are more complex in the east. The second sign is that temperature gradient in the east is higher due to the hidden magma centres and "thermal domes", which speed up changes in the feldspars and carbonates and affect the katagenesis. The third sign is that in result of deformations, mineral structural defects are opened and morphology of cavitated microspace changes. In conditions of the rock uneven volumetric compression, width and length of the cracks opening inside and between the mineral grains increases. These processes affect the state of the rock mass.

Keywords: Donbass, sandstones, katagenesis, minerals, deformations, quartz.

Abstract.

Influence of geological factors on the gas-bearing coal rock mass was studied. The key task was to determine location of the methane-accumulating zones in the mine field sector under the study and prepare their description. Involving of some geological factors for predicting the methane-accumulating zones makes possible to consider the coal-rock massif, in which mining operations are conducted, as a complex system, which is formed under the action of geological, geomechanical and geodynamic processes, and to properly arrange methane-draining works.  The research was conducted for the Pokrovskoe Mine and included choosing of geological factors and determining of their influence on the gas-content in the coal rock massif and analyzing of and building of prediction maps for the methane-accumulating zones.

Keywords: methane, geological factors, coal seam, fracture, collectors.

UDK 548.4: 553.12

Author:

Antipovich Ya.V., M.S. (Tech.)

(IGTM NAS of Ukraine)

Abstract.

Results of research on evaluating gas inclusion volumes in quartz grains of Donbas sandstones are presented. Sandstone thin rock sections from samples, which were taken within the middle and late catagenesis substages, were studied. The thin rock sections were examined by optical microscope ПОЛАМ – Р111 with magnification of 100 - 1200 times and with immersion solution.

It is stated that during the transition from middle to late catagenesis substages, total amount of gas inclusions in quartz sandstone grains decreases. This process is different in isolated inclusions and inclusions that decorate the Böhm strips. The results can be used in studying the gas-form transformations in the rocks and gas-dynamic phenomena in the rock mass.

Key words: gas inclusions, quartz grains, sandstone, paleodepth, carbonic deposits.

Abstract.

Today, methane, being one of the most perspective potential sources of energy, is at the same time a source of constant danger for miners and one of the largest polluters of environment.

The purpose of this scientific work was to develop a methodology for calculating parameters of the ground degassing gas-transport system and technical solutions, which could improve safety of operation, immediacy of control parameters and energy-efficiency of management. For proper usage of the borehole output pressure, a scheme of reconstructed ground gas- transport system (GTS) was developed with using of existing gas-pipeline, diameter 325 mm.

On the basis of the research results, a simulation model was developed for designing and studying the ground degassing systems (GDS). With the help of this simulation model, the mines’ specialists can calculate the borehole pressure and consumption necessary to ensure the needed gas voume for cogeneration unit and automobile gas-filling compressor station (AGFCS). It is also possible to control pressure in the key points and loss of pressure in the gas-main pipeline sections.

Keywords: pipeline transportation system, boreholes, pressure.

Abstract.

A method of and technical equipment for preventing coal and gas outbursts during the mining operations in the gas-bearing coal seams are described, which assume seam drilling from the face and further high-pressure injection into the drilled wells. The proposed method assumes that a drilling rig and high-pressure injector move together on the scraper conveyor frame with the help of carriages, which are connected with the scrapers of conveyor installed on the tunnel floor. The wells with diameter of 50 mm and length of at least 25.0 m are drilled by the drilling rig. A modular complex is described, which is designed for preventing gas and coal outbursts (hereinafter the MCPO) during the mining operations in the gas-bearing seams, and which consists of a bore, bore bar, rock cutting tool for drilling blastholes or wells and high-pressure pumping plant for pumping fluid into the coal seam through the blasthole or well. The MCPO differs by its design in which drill bit and pump are arranged on two separate carriages installed on the scraper conveyor frame at a distance of not less than 30 m from each other. As the carriages are connected with the conveyor scraps by anchors they can move simultaneously along the whole length of the face. This method and equipment essentially improves the MCPO mobility, drifting rate and safety of miner labor.

Keywords: outburst, drilling rig, scraper conveyor, aggregate complex, high-pressure pump installation.

THE DEFORMATION MODEL OF THE WET COAL-MASS UNLOADING

UDK 539.32:622.831:622.234.5

Author:

Polyakov Yu.Ye., Master of Sciences

(IGTM NAS of Ukraine)

Abstract.

In this article, a problem of unloading a coal seam, which is not in extremely stressed state, is considered. It is assumed that bearing capacity of the coal seam, even decreased due to water saturation, exceeds the rock pressure. It is further assumed that an unloading factor is the elastic modulus decrease with increased coal humidity. It is believed that the ξx, ξy, ξz deformations of the dry and wet coal are the same. When a wet area is small, a total load of the roof is taken by the dry coal, whose area is only slightly smaller than the original one. With the dry coal area decreasing, vertical stress therein increases and causes a significant additional increase of vertical deformation, which is transferred to the wet coal and causes additional stresses. Decreased strength of the wet coal is a main factor, which determines a rate of the buttock unloading from the rock pressure in the process of the rock hydraulic breaking.

Keywords: hydraulic power, elastic modulus, deformation unloading, coal humidity, strength limit, hydraulic breaking, humidification area.

Abstract.

As a result of long period of preparation factories operation sludge collectors that are large in size and depth were formed. Content of sludge collectors as a result of technological and geomechanical processes is divided into mineral raw materials concentration that can be re- preparated in certain places. Sludge collectors development is made as a rule for the formation of free capacity for newly generated wastes storing. It does not take into account the location of the places of mineral raw materials concentration and wastes that were generated after re- preparation are placed into the sludge storage again.

In the article improved technological schemes of content extract and preparation wastes content pre- preparation, of the use of generated wastes and of the process water purification are given for conditions of a sludge collector operation finish.

The proposed schemes of mineral raw materials extracting from the sludge collector and their preparation in the semiportable, cleaning pre-enrichment complex represent as a complete eco-targeting cycle of rational nature using and environmental situation improving.

Keywords: sludge collectors, wastes content, re- preparation, water purification, resource intensity increasing, environmental situation improving.

Abstract.

The objective of this work is to establish parameter conformity for the mine transport system, which includes excavator-automobile complexes, in order to create a mathematical model of optimal parameter calculation for mining works and their further use in models of design work.

A mathematical model is developed, which initially analyzes rock geometry within the bounda-ries of the quarry fields, and then transforms the obtained results into the design and schedule of mining operations.

It is proposed to optimize location of the highwall in the "Vostochnyy" quarry of the Ekibastuz coalfield by applying the excavator-automobile complexes in technology of surface mining opera-tions. The objective is realized through sequential determination of design parameters for mining and opening-up areas by the following stages of the filed development: work of mining complex by continuous technology; work of overburden complex by cyclic-flow technology with using of the excavator-automobile complexes in the working area; and by cyclic technologies with usage of ex-cavating and railway systems.

In the work, the project time schedules of mining operations are compared for the whole period of the transport system reconstruction by existing and the proposed technologies, and as a result, an expert assessment is made concerning any needed changes in the design scheme of mining opera-tions.

Keywords: quarry, coal, prolongated field, mine transport system, modeling, excavator-automobile complexes.

Abstract.

Internal dumping technology is widespread in the deep iron ore open pits. In most cases, when deciding on its usage, mining situation is analyzed narrowly, excluding the complex influence of internal dumps on the open pit’s cargo flows system. The purpose of the research is improvement of the shovel-truck system efficiency using the internal temporary dumps.

The analysis is based on the current operating conditions of shovel-truck systems in deep iron ore open pits, characteristics of the internal dumping technology, geological and mining conditions that determine its application scope. Preliminary methodology of open pit transport scheme analysis with the further technique of internal dumping justification is showed in the article. The feature of the method is its ability to define the rational application areas of the technological schemes with internal dumping, ring movement and passing loading of haul trucks.

In the proposed version, it is done in a few steps. Initially, system of optimization models is applied to define the required number of transport to perform the mining plan and to test the existing haul truck fleet transportation possibilities. After it, creation of the optimally located internal dump is checked as an opportunity to reduce the insufficient transport work. Lastly, simulation model is built to check the efficiency of the shovel-truck system in the changed conditions. The use of the methodology will significantly improve the quality of engineering decisions about the internal dumping usage in the deep iron ore open pits.

Keywords: shovel-truck system, ring movement scheme, internal dumping, linear optimization, simulation.

UDK 622.271:622.7.012

Author:

Lutsenko S.A., Ph.D. (Tech.), Associate Professor

(State HEІ “KNU”)

Abstract.

Ore output is one of the main parameters of the open pit, which defines economic figures of any mineral opencast mining. The objective of the study is to improve methods for determining open-pit productivity with taking into account the required reserve volume available for extraction.

The method for determining open-pit productivity has the following idea in its basis: mine productivity is to be determined basing not only on maximum intensity of mining operations (maximally possible arrangement of mining excavators), but also with taking into account interaction of width of operational area and length of active stripping front, which ensure a required volume of reserves available for the extraction. This idea was accomplished by determining rate of operational area width impacting on stripping zone length and volumes available for extraction.

The results of completed studies may be used by design organizations and mining enterprises for evaluating any mine productivity.

Keywords: width of operational area, length of active stripping front, open-pit productivity, reserves available for extraction.

Abstract.

A possibility to create a highly efficient and safety power complexes consisting of a storage battery with charger for using in the mine storage-battery locomotives was studied. Objective of the study: to develop physical models, and to determine rational parameters for the battery charging systems, as well as to conduct experimental study with them. Different technical solutions on chemical current sources and methods of their charging known in the world and in Ukraine were analyzed. The following research priorities were established: to develop scientific bases for creating battery charging systems based on the lead-acid batteries of traction type; to improve lead-acid battery stability and to minimize gas emissions in them; and to improve energy efficiency and safety of charging process in the coal mines. Current technical level of equipment and methods for designing the energy-efficient charging systems were analyzed. The following methods were chosen as the priorities: usage of smeared electrode plates with double separation in combination with compression of electrode assembly, and gas recombination inside the battery by oxygen cycle. Principles and algorithms of modeling were developed for calculating basic parameters of the battery charging systems. The most optimal parameters and conditions for the discharge regime were determined, which would provide energy efficiency and fire and explosion safety. In order to realize this charging regime, a reliable, safety and energy-efficient charger is proposed, effectiveness of which is ensured by the following features: minimum components in the power electronics, restrictive-and-regulating resistor, and natural air cooling.

Keywords: tractive storage battery, battery charger, battery charging system, mine locomotive, energy-saving technology.

Abstract.

Development and design of percussion machines require precise calculation of their moving parts, such as: elements of valves, locking sleeve, strikers, etc. Existing methods of calculation cannot fully solve a problem of the machine colliding parts.

This article provides a solution of the problem of colliding bodies, in which equations of the body motion dynamics and equations of distance passed by the bodies form a system of equations with taking into account deformation of the colliding parts. Solving of this system of equations makes possible to determine not only current forces of the body speed and acceleration, but also duration of interaction between the colliding bodies and rate of their deformation.

This method of determining parameters for the colliding bodies can be used for a wide range of applications where interaction between the bodies occurs in areas with elastic deformation.

Keywords: locking sleeve, striker rod, downhole hammer, motion equation, colliding parts.

Abstract.

The high-temperature heating of carbon-bearing fuels with particle size of 50-200 microns was investigated in order to establish rational and kinetic thermal parameters, their influence on the heat-and-mass transfer and efficiency of thermal reactions in the reaction chamber at a changed specific heat flow qc = 104 ÷ 107 W/m2 and gas temperature Тк = (2÷6)·103K. The thermal parameter influence on the solid fuel gasification process was determined on the example of coal particles and water vapor heating at convective and radiant heat transfer.

The calculation results were compared, and it was concluded that influence of radiative heat transfer prevailed in the total heat flow in plasma reactor when Тк > 5·103 K.

Volume of the reaction chamber and its operation are calculated with taking into account thermal and kinetic parameters of the fuel high-temperature heating. It is shown that a process of the fuel thermal transformations is effective at temperature Тк ≤ 3000 K in the plasma-chemical reactor of the combined type.

Keywords: carbon-bearing environment, chamber, heating, temperature, kinetic parameters, thermal conversion, volume, efficiency of the process.

Abstract.

This paper proposes a method for intensifying the flue-gas cleaning from sulfur compounds in order to use it in heat exchangers and to improve environmental and energy efficiency and economic performance of the coal-producing enterprises. Different methods and equipment were considered for beneficial use of flue-gases heat. To ensure operation of such equipment in the mine’s energy complex, it is necessary to use contact heat exchangers. Basing on analysis of peculiar thermophysical processes in the contact heat exchangers, it is recommended to use designs with spray-type devices and centrifugal heat exchangers. The contact heat exchangers of such design have significant resource for intensifying the thermal processes. Different methods are discussed for cleaning the flue gases from sulfur dioxide and feeding them to the contact heat exchangers. An oxide-manganese method was chosen, as it is related to the "dry" method of the flue-gas cleaning. A layout scheme is proposed for devices for flue-gases cleaning from sulfur dioxide and their usage in contact heat exchangers in order to supply heat to the energy unit in the mine’s energy complex. The stages of main chemical reaction of the oxide-manganese method is considered. In order to intensify this reaction, it is proposed to apply pulsation to the flue-gas flows entering the apparatus of their cleaning from sulfur dioxide.

Keywords: contact heat exchangers, sulfur dioxide, manganese oxide, intensification, flow
pulsations, flue gases.

Abstract.

The aim of research was to evaluate a radiation dose for the workers in the mining and metallurgical enterprises, as it is necessary for their safety labour and health protection. For the purpose to assess how radiation impacts on the workers, a method for calculating an effective dose was developed, which took into account the following types of irradiation:

- external irradiation of the staff and workers;

- internal irradiation through inhalation of radionuclides of the uranium, thorium and actinouranium classes;

- internal irradiation by radon and its decay products;

- internal irradiation through the oral intake of radionuclides.

A method for calculating doses of the employee irradiation by natural radionuclides is developed and tested.

 The problems of irradiation risk for workers and employees at enterprises of mining and metallurgical industries are considered.

The studies and calculations have showed that the annual effective dose during the technological cycle of works is different for different jobs and enterprises, and radiological studies should be included into certification of the workplaces.

Keywords: labor protection, effective dose of internal irradiation, external irradiation, natural radionuclides of the uranium and thorium classes, mining and metallurgical enterprises.

Abstract.

The necessity to transit from considering optimization of aerodynamic parameters for the main fans and mine ventilation network as definition of separate problems to consideration of the complex system «main fans - mine ventilation network» is grounded. Specific features of such complex system and basic criteria of optimization of aerodynamic parameters for the main fans and ventilation network are described. It is stated that law of resistance of separate elements in the system «main fans - mine ventilation network» can differ from quadratic law, hence leading to the changed system of equations, which describe the Kyrkhgof laws, and necessity to develop new methods for calculating the mine ventilation systems. Criteria are also proposed for estimating structural and parametric interconnection between the main fans, satisfaction of which would allow to transfer the system «main fans - mine ventilation network» to maximally sectional or fully sectional ventilation. The text material is illustrated by examples from the 1/3 Novogrodovskaya Mine.

Keywords: mine ventilation networks, main fans, criteria, interconnection between the main fans, nonquadratic law of aerodynamic resistance.

Abstract.

Nowadays there no proper mechanisms of mines closure, which would consider all ecological consequences from technological equipment stopping to the development of sustainable functioning strategy for post-industrial territories. It is stated that liquidation of not-paying coal mines does not ensure their influence stopping on the environmental components. In most cases the ecological problems arising on different stages of not-paying mines liquidation affect the further development and ways of use of adjacent territories. Mines liquidation projects consider all sources of negative influence on natural environment to be eliminated by the end of mine closure process. As based on the concept of all possible ecological risks in the process of coal mines liquidation, the conclusion is drawn about the approaches to assessment of the degree of any negative situation occurrence. The approaches are absolutely equal and can be used while developing methodological base for concession of priority and procedure for nature-conservative measures for coal mines under liquidation.

Keywords: mine liquidation, ecological risks, mineralization, water intake, waste dumps, mine surface complex, deformative process.
