摘要
针对深部开采工作面回采始终面临着高压、高温、高瓦斯的“三高”环境,常规单一加大煤柱留设宽度与加强支护相结合的方式,已无法解决“高压”带来的巷道变形严重问题,采用本煤层、仰角钻、高位钻场联合抽采方式对于高瓦斯的治理收效甚微的问题,黑龙江龙煤鸡西矿业集团下属煤矿开展深部回采工作面围岩控制与瓦斯治理新实践研究,提出了巷道围岩稳定性控制技术体系和瓦斯治理技术实践方案,效果价值分析表明:该实践方案对于深部回采工作面井巷工程建设具有重大价值,为深部回采工作面的灾害防治提供科学依据和技术支持。
In response to the"three highs"environment of high pressure,high temperature,and high gas in deep mining face,the conventional combination of increasing the width of coal pillars and strengthening support is no longer able to solve the serious problem of tunnel deformation caused by"high pressure".The combined extraction method of this coal seam,angle drill,and high-level drilling field has little effect on the treatment of high gas,Heilongjiang Longmei Jixi Mining Group's subordinate coal mines have carried out new practical research on rock mass control and gas treatment in deep mining face.They have proposed a technical system for controlling the stability of tunnel rock mass and a practical plan for gas treatment technology.The value analysis of the effect shows that this practical plan has significant value for the construction of deep mining face roadway engineering,providing scientific basis and technical support for disaster prevention and control in deep mining face.
