| 摘 要： | 针对松藻煤矿煤层松软,透气性差,现有石门揭煤技术工程量大,揭煤时间长等问题,采用深孔预裂爆破和高压水力割缝快速石门揭煤技术,分别对深孔预裂爆破的钻孔布置方式和爆破参数,高压水力割缝的钻孔布置方式和水力学参数进行了研究。应用结果表明,深孔预裂爆破快速石门揭煤技术可使钻孔平均进尺数下降806.7 m,且石门揭煤时间由72.3 d下降为32 d,揭煤时间缩短55.3%;高压水力割缝快速石门揭煤技术使钻孔平均进尺数下降905.7 m,且石门揭煤时间由72.3 d下降为27.7 d,揭煤时间缩短61.2%。上述2种方法都可解决揭煤时间长,工程量大的问题,其中高压水力割缝石门揭煤技术效果更好。
