综合防灭火技术在工作面停采撤架期间的应用

摘要

Based on the analysis of the causes of coal spontaneous combustion in №S205 fully mechanized caving face of Qijiapo Coal Mine , the comprehensive fire prevention and control technology of preventing air leakage , pouring three-phase foam, grout and polymer colloid by high-level drillings and pre-supports drillings was established .By using the comprehen-sive technology , the problem of coal spontaneous combustion in goaf during the period of supports withdrawing was solved and the safety withdrawing of mining equipments in fully mechanized caving face was ensured .%针对秦源煤业戚家坡煤矿S205综采工作面的实际情况，分析了自然发火的原因，并制定了控漏风、高位钻孔和架前钻孔注三相泡沫、灌浆和高分子胶体等综合防灭火技术，消除了撤架期间采空区发火的隐患，保证了工作面设备的安全拆除。
