上向分条进路充填采矿法在望儿山金矿的应用

Application of Upward In-strips Drift Cut-fill Method in Wangershan Gold Mine

望儿山金矿现主要采用上向分层充填采矿法,但对于深部Ⅰ号矿脉的倾斜中厚矿体,因矿岩非常破碎,赋存条件变化较大,按原有采矿方法和工艺已不能达到开采要求。采用上下盘分条进路充填采矿法,已取得了良好效果;并就该方法涉及的几个关键进行了分析讨论。

Wangershan Gold Mine now mainly uses upward slicing-filling method. But for the inclined medium thick orebody in deep No.1 vein which is characterized by very fractured ore rock and greatly varied occurrence conditions, the original mining method and technology can't meet the extraction requirements. Therefore, upper and lower side wall in-strips drift cut-fill method has been tried and achieved good results. Several key points in using this method are discussed.
