摘　　要：为解决五家沟煤矿15301工作面推进过程中采空区悬顶面积大、不易垮落的问题,提出了深孔爆破强制放顶技术,设计了炮孔参数及布置方案。对工作面顶板实施深孔爆破后,工作面的来压强度明显降低,满足矿井安全生产的需求。In order to solve the problem of large hanging roof area of goaf and not easy to collapse in the 15301 working face of Wujiagou Coal Mine,the forced caving technology of deep hole blasting is put forward,and the blasthole parameters and layout scheme are designed.After the implementation of deep-hole blasting on the roof of the working face,the incoming pressure strength of the working face is obviously reduced to meet the needs of mine safety production.
