摘　　要：由于63上06工作面轨顺沿空布置,边缘处基本顶形成悬梁,未充分垮落,为减小区段煤柱的应力集中,采用顶板深孔爆破断顶卸压技术,对巷道顶板进行预卸压处理。同时超前对63上06运顺顶板进行爆破断顶卸压,避免63上06工作面回采完毕后,采空区与63上07顺槽边缘基本顶形成悬梁,实现工作面安全回采。As the rails of the 63 upper 06 working face are arranged along the goaf,the basic roof at the edge forms a cantilever beam,which does not fully collapse.In order to reduce the stress concentration of the coal pillars in the section,the roof deep hole blasting broken roof pressure relief technology is used to improve the roadway The top plate is pre-stressed.At the same time,blasting the roof of Yunshun 63 on 06 to relieve the pressure in advance to prevent the goaf and the edge of the groove on 63 on 07 from forming a suspension beam after the end of the 63 on 06 working face,so as to realize safe mining on the working face.
