摘要
阳煤一矿S8303工作面为实现高产高效,通过优化设计变双翼为单翼工作面,其间需要通过5条空巷。通过探索高水充填材料充填、回填煤与高水充填材料混合及支设木垛等技术实践,有效的预防了超前支撑压力作用下大面积冒顶,保证了回采安全,为过空巷积累了实践经验。
By changing double-wing working face into single-wing one to realize high yield and efficiencY at S8303 working face,the author proposes the technological practice on filling with high-water filling material mixed with backfill coal and layingwooden chock, which can prevent the large-area roof fall under advance abutment pressure, guarantee the stoping safety andaccumulate experience of crossing gob.
