摘要
针对固庄煤矿5号回风井通风系统不合理、主扇运行效率偏低、煤层自燃防治困难的现实问题,通过停止5号回风井主扇运行,简化通风系统,实施技术改造,取得了较好的技术经济效果。
The ventilation system of 5# return airshaft in Guzhuang Coal Mine is not reasonable, the operation efficiency of main fan is low, prevention and control of coal seam spontaneous combustion is difficult. By stopping main fan operation of 5 # return airshaft, this paper simplified the ventilation system, implemented technological transformation and achieved good technical and economic effect.
