摘要
为解决某矿山8/9煤层瓦斯浓度超标问题,基于10煤层不具备卸压开采条件,开采技术人员决定在软岩层内设计综采工作面,开展特定区域瓦斯治理工作。经测量可知,软岩工作面预设开采走向长度860m,倾向长度104m,综采工作面标高2.0m。以地质保障技术为支撑,制定巷道围岩治理规划方案,以期降低场区瓦斯浓度,保证开采作业安全。
In order to solve the problem of gas concentration exceeding the standard in 8/9 coal seam of a mine,based on the fact that 10 coal seam does not have the condition of pressure relief mining,the mining technicians decided to design the comprehensive mining face in the soft rock layer and carry out the gas control work in a specific area.According to the survey,the preset mining strike length of the soft rock face is 860 m,the dip length is 104 m,and the elevation of the comprehensive mining face is 2.0 m.With the support of geological support technology,the plan of roadway surrounding rock treatment is formulated in order to reduce the gas concentration in the field and ensure the safety of mining operation.
