摘要
根据城山煤矿3B煤层右四工作面实际情况,在工作面上部采空区内和尾排巷内布置测点,对采空区气体进行实时分析,确定3B煤层右四工作面采空区"三带"的范围,为城山煤矿3B煤层煤炭自燃防治提供了科学依据,保证了工作面安全回采。
According to the actual conditions of 3B layer right No.4 working face of Chengshan Coal Mine,measuring points were laid out in upper goaf and tail roadway of the working face, real-time analysis of goaf gas was also carried out,and the region of ＂Three Zones＂ of 3B layer right No.4 working face was also determined, which has provided a scientific basis for coal spontaneous combustion prevention of Chengshan Coal Mine, and has ensured the safety of working face mining.
