摘要
针对柳塔煤矿工作面在推进中需要通过4条空巷的问题,提出在工作面回采前对空巷进行了加强支护;工作面推进中加强对工作面矿压的观测,尽量使空巷避开工作面的周期来压,最终安全顺利地通过了空巷,为相似开采条件的工作面提供了实际的参考经验。
Aiming at the problem that coal mining face need to pass through 4 abandoned roadways in Liuta Coal Mine,the measures,such as reinforcing support for abandoned roadways before working face mining,strengthening mine pressure observation during the working face mining,and avoiding periodic pressure when crossing abandoned roadways were proposed.By taking these measures,the mining face passed through the abandoned roadways smoothly,which provide a reference for the similar mining conditions of working face.
