开滦矿务局唐家庄煤矿是一个具有近七十年开采历史的衰老矿井,1991年元月经中国统配煤矿总公司批准核销了统配生产能力,进入了收尾阶段。但矿井尚有部分边角采区,艾家圈风井和七百户风井两个井筒煤柱需要回收。上述残余储量的回收只能利用现有巷道系统和通风设备。因此,造成井下生产地点分散、通风线路长、通风阻力大、风量严重不足等困难状况。面对上述问题,采用常规 The Kailuan Mining Administration Tangjiazhuang Coal Mine is an aging mine with nearly 70 years of mining history. In January 1991, it was approved by the China General Coal Mines Corporation to write off the total production capacity and entered the final stage. However, there are still some mining areas with corner mining area, Ai family circle wind wells and 700 wind shaft two wellbore pillars need to be recycled. The above recovery of residual reserves can only utilize the existing roadway system and ventilation equipment. As a result, the underground production sites are scattered, the ventilation lines are long, the ventilation resistance is large, and the air volume is seriously insufficient. Faced with the above problems, using conventional
