摘要
根据前坪铜矿井下破碎岩体的施工现状,依据新奥法基本原理,通过钢拱架锚网喷联合支护工艺在破碎岩体巷道掘进中的试验研究,确定最优支护工艺。现场掘进试验结果表明,新奥法适用于破碎岩体条件下的巷道掘进,可取得较好的技术经济效果。
Due to the current situation of drifting in underground broken rock mass in Qianping Copper Mine,combined support technology,steel arch and bolt-mesh-shotcrete is tested based on New Austrian Method and optimal support technology are obtained.The in-situ drifting test results show that New Austrian Method is applicable for drifting in broken rock mass,which can obtain better technical and economic effects.
