内蒙古伊泰煤炭股份有限公司诚意煤矿5103综采工作面上覆4#煤房采采空区已出现火区,通过钻孔对火区进行监控,并对5#煤采空区的垮落带和断裂带高度进行计算,分析得出5#煤开采不会受火区明火的影响,但有毒有害气体会侵入工作面造成隐患。因此,决定在5103综采工作面采用均压通风技术,通过增压调压试验观察,效果明显,彻底解决了工作面受火区威胁问题,安全完成了房采工作面的回采。
Inner Mongolia Yitai Coal Co., Ltd. Sincerity coal mine 5103 fully mechanized coal face overlying mining area # 4 coal mined area has emerged fire area, through the borehole to monitor the fire area, and 5 # gob of caving zone And the height of the fault zone, it is concluded that the mining of No. 5 coal will not be affected by the open flame in the fire area, but the poisonous and harmful gas will intrude into the working face and lead to potential problems. Therefore, it is decided to adopt pressure equalization ventilation technology in 5103 fully mechanized coal mining face and to observe it through supercharging and pressure-regulating test. The effect is obvious and the threat to the fire area in working face is completely solved, and the mining of house face is completed safely.
