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.

Article preview

The article analyzes the impact of endogenous fire hazard of the development of strata prone to spontaneous combustion, in particular, with the use of modern efficient equipment, on the technical and economic performance of the mine. The conclusion is made about the necessity of differentiated approach in the choice of technology for the development of mined seams. The effective technological scheme of development of strata prone to spontaneous combustion is proposed. The influence of the first layer development on the stress-strain state of the underlying layers is investigated and rational parameters of technological schemes are determined. The economic effect from the introduction of the developed technology is calculated, which is obtained by reducing the number of endogenous fires and minimizing the damage in case of their occurrence.

Determination of rational location of sectional preparatory excavations at layer systems of development

Article preview

The paper analyzes the results of mine observations on the condition of area preparatory workings during layer mining of thick gentle strata of Kuzbass. The conclusion is made about the necessity of additional justification of the location of area preparatory workings of the 2nd layer, providing the reduction of costs for their maintenance. The stress-strain state of the rock massif (STS) "perturbed" by the 1st layer mining was investigated. The nature and degree of influence of the 2nd layer overmining were established. The rational location of the 2nd layer preparatory mine workings was chosen for the sloping mining of layer III of the Tom-Usinsky region of Kuzbass. The economic effect from the implementation of the developed recommendations is calculated, which is obtained by reducing the cost of maintaining the operational condition of the area excavations.
