摘要
介绍了高分段采矿法的回采工艺及其配套设备 ,用高分段采矿法代替中深孔矿房法 ,用KQJ- 10 0B潜孔钻机代替YGZ - 90深孔钻机。应用结果表明 ,万吨采掘比降低 2 1m ,每米崩矿量提高 3 88t,吨矿成本下降4
The extraction technology and complementory equipment of high sublevel mining method are described.The application of high sublevel mining instead of medium and deep hole room work and of KQJ-100B down-hole drill instead of YGZ-90 deep hole drill has brought a reduction of stripping ratio per ten thousand t of 21m,an increase of caved ore of 3.88t and a decrease of cost per ton ore of $4.81.
