摘要
简述广西大新锰矿由露采转地采后,通过引进坑内钻探技术,对地下矿山生产建设起到了重要作用。凿岩台班的月进尺由原来的60～80 m提高到350～450 m,钻探成本下降了3 250元/m,取得了良好的经济效益。
This paper made a suggestion of briefly-transferred opencast mining in Daxin Mn-mine after an introduction of pit drilling technology,as plays an important role in the construction of underground mining production. Also,rock stage in drilling per month achieves good results from original 60 ～ 80 m up to 350 ～ 450 m and it has cost reduction by RMB 3 250 yuan / m.
