机械化浅孔留矿嗣后充填法在望儿山薄矿体的应用

Application of mechanized shallow hole shrinkage and subsequence filling in thin orebody mining of Wangershan mining area

对于黄金矿山,薄矿体的采矿方法以及回采效率一直是采矿界的难题。按照常规的削壁充填法进行回采,采矿效率低,采用机械化进路回采,贫化率高。针对上述问题,应用机械化浅孔留矿嗣后充填法采矿,取得了良好的经济效益。

For gold mine, thin orebody mining method and extraction efficiency is always a difficult problem in mining industry. The mining efficiency of using conventional waste-lifting stoping is low, and the dilution rate of using mechanized drift stoping is high. In view of these problems, the mechanized shallow hole shrinkage and subsequence filling method was used, and good economic benefit was got.
