摘要
通过对老石旦煤矿目前通风系统存在的问题进行分析,确定了矿井通风系统优化改造方案,对矿井9#煤层、9#煤层通12#煤层、12#煤层通16#煤层联络巷进行封闭,提高了矿井有效风量率,缩短了矿井通风路线,达到优化通风系统的目的,确保了矿井的安全生产.
Through analysing the problems existing in the ventilation system of Laoshidan Coal Mine at present, the optimal modification scheme of mine ventilation system was determined. The connecting roadways in No. 9 coal seam, from No. 9 to No. 12 coal seam and from No. 12 to No. 16 coal seam were sealed. The effective air quantity was improved and the air line was shortened. It achieved the goal of ventilation optimization and safety production.
