廉江银矿采场接顶充填技术

Stope-Roof-Contacted Filling Technique at Lianjiang Silver Mine

廉江银矿的矿岩稳固性很差，采用上向进路尾砂胶结充填采矿法。接顶充填是该采矿法的关键技术之一。本文介绍了该矿采用的强制接顶充填、分区充填及嗣后区域充填的综合技术。

The stability of ore and rock in Lianjiang Silver Mine is very poor so that an overhand slice and drift mining with cemented tailings filling was used for mining.Roof-contacted filling is one of the critical techniques for this mining method. This paper introduced the comprehensive technology of forced roof-contacted filling,individual area filling and sebusequently regional filling used in the mine,this technology made the problem of roof-contacted filling of drift to be solved.
