魏家地高瓦斯易自燃煤层综合防灭火技术

针对魏家地煤矿煤层瓦斯含量高、容易自燃、开采煤层厚度不稳定、近距离煤层群开采等特点,提出了加强自燃的监测和预报,建设完善防灭火装备,强化防灭火管理和完善应急机制等矿井防灭火体系的整体方案,对保障矿井安全生产意义重大。

Fire preventing and extinguishing technique in Weijiadi Coalmine

The main mining coal seams in Weijiadi coalmine are high-methane,spontaneous combustion,near-neighbored mining,thicknesses unstable.According to these characters, a systematic fire preventing and extinguishing scheme is put forward,which includes strengthening inspection and monitoring,deploying coal spontaneous combustion prediction,setting up fire extinguishing equipments and systems,intensifying management on fire prevention and consummating emergency response mechanism.The study is very important for safety mining in the coalmine.
