摘要
介绍了店坪煤矿5-200工作面的总体情况,根据预留巷道周围的地质条件,通过对中国矿业大学(北京)切顶卸压理论的研究,经过一系列理论计算及方案论证,决定采用切顶卸压沿空留巷无煤柱技术开采方案,并设计了切顶留巷顶板预裂爆破参数,提出了切顶卸压沿空留巷无煤柱开采设计方案;已在店坪煤矿5-200采煤工作面推广应用,取得了阶段性的良好效果、较好的安全评价和经济效益。
This paper introduces the general situation of No. 5 -200 working face in Dianping Coal Mine. Based on the geological conditions around the reserved roadway, studies the theory of pressure relief with roof cutting origina-ted by the China Mining University （ Beijing） , after a series of theoretical calculations and demonstration, It is decid-ed to adopt the design scheme of gob side entry retaining, of pressure relief with roof cutting at No-pillar mining condi- tion, and the parameters for the pre-splitting blasting of the roof are also designed, the design scheme has being im-plemented smoothly in No. 5 - 200 working face in DianPing coalmine with comprehensive qualified results.
