摘要
针对甲玛铜矿高海拔环境和缓倾斜厚大矿体赋存条件,初选了两种大直径束孔高分段空场嗣后充填采矿方法,经综合技术经济比较,最终确定采用阶段凿岩束孔高分段爆破方案,并进行工业试验。现场实践表明,本方案是高原环境束状孔高分层落矿、边排孔轮廓控制、大型无轨设备出矿、高效采场充填的技术集成及应用示范,实现了高海拔地下金属矿山安全高效采矿技术的新突破。
According to high altitude and slowly inclined large and thick ore body of Jiama Copper Mine,two mining methods are selected preliminarily with large diameter bundle-holes of high-sublevel open-stope succeed by fill.By comparing the comprehensive technical and economic indices of the two methods,the mining scheme of stage drilling and highsublevel blasting with bundle-holes is conducted.Industrial experiments are carried out.The practice shows that the method realized technology integration and application demonstration at high altitude mining of high-sublevel blasting of bunchholes,contour control of side holes,ore drawing with trackless equipment,and efficient stope filling.It is a new breakthrough of safe and efficient mining technology for underground metal mine at high altitude.
