Improvement of technological schemes of mining of coal seams prone to spontaneous combustion and rock bumps

Article preview

On the example of the Alardinskaya mine, the problem of underground mining of seams prone to spontaneous combustion and rock bumps in the conditions of the Kondomsky geological and economic region of the Kuznetsk coal basin is considered. The contradictions in the requirements of regulatory documents for the width of the inter-panel coal pillars in the mining of seams with longwalls in conditions of endogenous fire hazard and in the mining of seams that are dangerous due to geodynamical phenomena are discussed. These contradictions impede the safe mining of seams using traditionally used layouts with the danger of spontaneous combustion of coal and rock bumps. A mining-geomechanical model is presented, which is used for numerical three-dimensional simulation of the stress-strain state of a rock mass with various layouts for longwall panels using the finite element method. The results of the numerical analysis of the stress state of the rock mass immediately before the rock bump are presented, and the main factors that contributed to its occurrence during the mining of the seam are established. A dangerous degree of stress concentration in the coal seam near the leading diagonal entries is shown, especially in conditions of application of abutment pressure from the edge of panels’ gob. The analysis of the features of stress distribution in the inter-panel pillar at different widths is carried out. Recommendations for improving the layout for the development and mining of coal seams that are prone to spontaneous combustion and dangerous in terms of rock bumps in the conditions of Alardiskaya mine have been developed. The need for further studies of the influence of pillars for various purposes, formed during the mining of adjacent seams, on the stress-strain state of previously overmined and undermined seams is shown.

Improving the efficiency of the technology and organization of the longwall face move during the intensive flat-lying coal seams mining at the Kuzbass mines

Article preview

The reasons for the lag of the indicators of the leading Russian coal mines engaged in the longwall mining of the flat-lying coal seams from similar foreign mines are considered. The analysis of the efficiency of the longwall face move operations at the JSC SUEK-Kuzbass mines was carried out. A significant excess of the planned deadlines for the longwall face move during the thick flat-lying seams mining, the reasons for the low efficiency of disassembling operations and the main directions for improving the technology of disassembling operations are revealed. The directions of ensuring the operational condition of the recovery room formed by the longwall face are considered. The recommended scheme of converged coal seams mining and a three-dimensional model of a rock mass to justify its parameters are presented. Numerical studies using the finite element method are performed. The results of modeling the stress-strain state of a rock mass in the vicinity of a recovery room formed under conditions of increased stresses from the boundary part of a previously mined overlying seam are shown. The main factors determining the possibility of ensuring the operational condition of the recovery rooms are established. It is shown that it is necessary to take into account the influence of the increased stresses zone when choosing timbering standards and organizing disassembling operations at a interbed thickness of 60 m or less. A sufficient distance from the gob of above- or undermined seams was determined to ensure the operational condition of the recovery room of 50 m, for the set-up room – 30 m. Recommendations are given for improving technology and organization of the longwall face move operations at the mines applied longwall mining of flat-lying coal seams with the formation of a recovery room by the longwall face.

Prevention of coal spontaneous ignition during mining of thick steep seams in Kuzbass

Article preview

The factors that have the greatest impact on the probability of occurrence of endogenous fires in the mining of powerful steep seams of the Prokopyevsko-Kiselevskoye field of Kuzbass have been established. The differentiation of endogenous fires by reservoirs in the conditions of Prokopyevskugol Management Company LLC was carried out. The influence of the main mining and technical factors on the probability of spontaneous ignition of strata was studied. It was concluded that during the mining of thick steep seams, the main cause of spontaneous ignition is the abandonment of interstory coal pillars, which are concentrated accumulations of destroyed coal. The principles of designing technological schemes for mining seams prone to spontaneous ignition are formulated. A method of mining powerful steep seams prone to spontaneous ignition that excludes leaving inter-story coal pillars and ensures reliable isolation of the mined area is proposed.

Improvement of technological schemes for mining of powerful steep and steep-sloped seams with sub-stage hydraulic extraction

Article preview

The structure of mineral resource losses during mining of thick steep-sloped and steep seams with the use of the system of under-stage hydraulic extraction in the conditions of OAO Prokopyevskugol was determined. The influence of the main mining-geological and mining-technical factors on losses of minerals was studied. The factors that have the greatest influence on the mineral extraction coefficient were determined. It is concluded that, when determining the height of the subfloor, it is necessary to consider the width of the squeeze zone formed at the border with the mined-out space. The method of determining the parameters of the squeezing zone in the area of the influence of the mining operations is developed. The principles of designing the technological schemes of the mine workings are formulated. Recommendations on the rational arrangement of sub-stage drifts in different mining and geological conditions were developed. The economic effect from the implementation of the developed recommendations was calculated.

Geomechanical justification of parameters of the development system of a thick steep layer in the case of sub-stage hydraulic extraction

Article preview

An analysis of the causes of accidents associated with dynamic collapses of the roof rocks in the development system with sub-stage hydraulic extraction in the mines of OAO Prokopievskugol has been carried out. The hypothesis about the mechanism of dangerous dynamic collapses of coal and roof rocks is put forward. It is concluded that, when determining the height of the subfloor, it is necessary to take into account the width of the pushback zone formed at the boundary of the clearing works. The influence of the main geological and mining-technical factors on the parameters of the squeezing zone was studied. It has been proven that the following factors have the greatest influence on the width of the squeezing zone: the depth of the mining works, the thickness of the mined seam, the strength of the coal. Recommendations for determining the height of the subfloor, providing safe working conditions for miners in the conditions of the hydro mine Tyrganskaya are developed. The method of mining subfloors with an increased height is proposed. For its implementation the size of the squeezing zone and the length of the working jet of the hydraulic gun is calculated and the position of the undestroyed coal zone is determined taking into account these parameters. Coal massif de-strengthening in this zone is made to exclude the coal pack hang-up by, for example, hydraulic fracturing or explosion of explosive charges. The economic effect of implementing the developed recommendations has been calculated.

Improvement of the system of mining by floor drifts with coal hydrotreatment

Article preview

In modern market conditions, the viability of coal mines is determined by the competitiveness of their products. In turn, the competitiveness of mined coal depends on production costs. The solution of the problem of production costs reduction is vital for practically all Russian mines. The most acute problem of decreasing costs is for mines developing powerful steep seams of Prokopyevsk coal deposit in Kuznetsk coal field, where there are big coal reserves, and mining and geological conditions don't allow to use high-capacity cleaning equipment. Objective prerequisites for a sharp reduction of production costs in the mining of powerful steep seams are created by the hydraulic technology of coal mining. The purpose of this work is to create patentable, cost-effective technological schemes to reduce the amount of cutting work, reduce losses and improve the safety of miners. The idea of the work is to increase the height of the substage due to advanced loosening of the coal in its upper part. As a result of this research, a method of excavation of thick steep seams was developed, which allows: to reduce the cost of cutting work (40-50%), to exclude dynamic phenomena such as an air wave with a high velocity pressure, associated with simultaneous collapse of the roof rocks in large areas.
