摘要
基于近距离煤层开采工作面过断层期间防火治理研究的不足,通过对朱集西矿开采煤层群11501工作面过断层期间CO超限的原因分析,结合现场实际情况,运用监测监控、封堵漏风、液态CO2降温、灌浆隔离、加强抽放和配合跳采技术等综合治理手段,解决工作面CO超限问题。
Based on the shortage of fire control research in the close distance coal seam mining working face passing through fault, the we analyzed reasons of CO overrunning during the period of 11501 working face passing through fault in Zhuji West Coal Mine, combined with the actual situation, used the comprehensive control means such as monitoring, sealing air leakage, cooling liquid CO2, grouting isolation, strengthening drainage and cooperating with skip-mining technology, which has solved the problem of CO overrun.
