摘要
介绍了五虎山煤矿1001工作面、1001工作面贫氧和1001工作面CH4、CO超限情况,针对该工作面属于浅埋藏、自燃煤层、地面漏风严重且受上分层老火区影响等因数,对该工作面采取了均(增)压方案进行防灭火,有效地解决了1001工作面的贫氧、采空区煤层自燃和CH4、CO超限危害。
In this paper, conditions of Wuhushan Coal Mine, 1001 working face, poor oxygen of 1001 working face, overlimit condi-tions of CH4 and CO in 1001 workfaee were introduced. Aiming at the complex conditions of shallow burial, spontaneous combustion of coal seams, serious ground air leakage and impact of stratification old fire area, pressure equalizing （increasing） technology was ap- plied for fire prevention and extinguishing, and the hazards of oxygen - depleted, coal spontaneous combustion in old goaf and overrun of cn4, CO in the 1001 workface were effectively solved.
