石上煤矿-900m胶带石门注浆堵水技术

摘要

丰龙矿业石上煤矿-900m胶带石门位于长兴灰岩内,溶洞裂隙非常发育。通过堵水,使巷道安全通过了含水地层,保证了巷道的安全施工。%-900 Belt Shimen is located in Changxing Limestone of Shishang Colliery,Fenglong Mining Industry Co.,inside which cave fissures are well developed.Block up water makes roadway through aquifer stratum safely,which ensures the safe construction of roadway.
