摘 要:某金矿的矿体围岩属于压碎性的炭质板岩及泥质粉砂岩,巷道掘进支护技术难度较大。原矿山采用木支护、钢拱架支护或混凝土砌碹支护等单一支护形式无法满足巷道支护要求。基于此,本文根据金矿矿岩的实际情况,设计了相应的爆破参数和支护形式,经工程实验后取得了良好的技术与经济效果,提升了矿井采掘的安全性。The wall rock of the ore body in a gold mine belongs to the crushed carbonaceous slate and argillaceous siltstone,and the roadway excavation and support technology is difficult.The original mine adopts single support forms such as wood support,steel arch support or concrete arch support,which cannot meet the requirements of roadway support.Based on this,according to the actual situation of gold ore and rock,this paper designed the corresponding blasting parameters and support forms,and achieved good technical and economic results after engineering experiments,which improved the safety of mine excavation.
