煤与瓦斯突出矿井回采工作面避难硐室布置分析

Analysis on Refuge Chamber Arrangement in Stope Face of Coal and Gas Outburst Mine

通过对煤与瓦斯突出矿井回采工作面现有避难硐室布置形式的分析,结合回采工作面巷道的掘进和工作面回采,提出了将回采工作面的避难硐室布置在瓦斯抽采巷道与工作面巷道之间,避难硐室安全入口和安全逃生出口分别布置在工作面巷道和瓦斯抽采巷上,使用时更易与灾区环境隔离,增加了井下回采工作面采掘人员遇险紧急逃生系统,更有利于保障遇险矿工生命安全和井下应急救援。

The current layout form of refuge chamber in stope face of coal and gas outburst mine was analyzed, combining with the mining and roadway driving in working face, the layout scheme was proposed, that the working face refuge chamber was arranged between the gas drainage roadway and working face roadway, avoiding the condition that the safe entrance and escape exit of refuge chamber were arranged in working face roadway and gas drainage roadway separately, providing easier isolation from disaster area. An emergent escape system was arranged for underground distress of mining and driving personnel, offering ensuranee for the life safety of miners in distress and emergency rescue.
