摘要
该文通过对莱芜市辛庄煤矿有限公司"2.20"自然发火事故的分析,因火区封闭不严,老空、围岩漏风涌出CO,造成在用巷道内CO浓度超标,威胁矿井正常生产的情况分析,通过优化治理方案,构建均压室,人为增加均压室负压,杜绝火区漏风,从而减少CO涌出的威胁。通过均压室的构筑,降低了CO的涌出,降低了治理成本,保证了在用巷道的安全。
This article through to the laiwu city xin zhuang coal mine CO., LTD. the analysis of the／＂2.20／＂accident of spontaneous combustion, due to the fire area closed lax, old empty, air leakage flow CO, surrounding rock in roadway caused by the CO concentration levels of threat to the normal production of the mine situation analysis, by optimizing the management plan, build pressure chamber, artiifcially increased pressure chamber negative pressure, eliminate ifre area air leakage, thus reducing the threat of CO. The construction of the pressure chamber through both reduced the CO, reduce the management cost, guaranteed the roadway safety in use.
