摘要
为了安全、高效、经济的回收-100m分段6线矿块采空区的矿石,根据-100m分段6线矿块地质条件,通过-110m分段布置五个出矿漏斗与-100m分段6线小矿体采空区对应,采用中深孔后退式扩漏拉槽,将-100m采空区的矿石漏到-110m分段漏斗槽内,用铲运机进行安全回收-100m分段6线空场法采空区残留矿石6500吨,品位0.78%,金属量50.7吨。
In order to recover the -100m safe, emcient and economical sectional line 6 ore goaf ore, according to -100m segment 6 line ore geological conditions, through the -110m arrangement of block five drawing funnel and the -100m section of 6 lines of small ore goaf corresponding to the deep hole back type expansion slot leakage, will -100m ore goaf leakage into the -110m segment funnel groove, with scraper section 6 line stoping goal-100m safe recovery of residual ore 6500 tons, grade 0.78%, the amount of 50.7 tons of metal.
