摘要
针对沙吉海煤矿B_6工作面CO异常,地面有塌陷,通过采取采空区气体连续观测、地面塌陷回填平整、工作面采空区注氮气、均压灭火等防灭火技术对采空区进行综合治理,通过治理,CO显著下降,火区得到控制。
iming at the abnormal Shajihai mine B6, ground subsidence, by taking the goaf gas continuous observation, ground subsidence backfill formation, empty of nitrogen injection, even pressure fire extinguished fire prevention and extinguishing technology on the integrated anagement of goaf working face in goaf, through governance, CO decreased significantly, fire control.
