摘　　要：切顶卸压技术已在诸多矿区成功应用,取得了巨大的社会效益,西山煤电集团杜儿坪煤矿作为典型的高瓦斯矿井,采用传统炸药爆破的方式进行巷道顶板岩层预裂爆破会带来很大的安全隐患。鉴于此,积极试验了水力压裂技术,提出了“低位致裂+高位弱化”的整体控制思路,并以68310回风巷为工程背景进行试验,现场切顶卸压效果良好。The cutting roof pressure relief technology has been successfully applied in many mining areas,and has achieved huge social benefits.Dushanping Coal Mine of Xishan Coal and Electricity Group is a typical high gas mine.Great security risks.In view of this,the hydraulic fracturing technology was actively tested,the overall control idea of"low-level fracturing+high-level weakening"was put forward,and the experiment was conducted with the 68310 return air lane as the engineering background.
