摘　　要：开采顶板不稳固的倾斜薄矿体,一直是令人棘手的问题。为探索和解决这一问题,本文推荐爆力运搬分段分块房柱采矿法,即采用短时小面积暴露顶板和爆力运搬出矿方法。这种采矿方法极大地提高了采场生产能力,降低了矿石贫化损失和采矿成本,对同类矿体的开采有明显的现实意义。It has always been difficult to mine thin moderate dip orebodies with unstable roofs. To tackle this problem, the paper recomends a new room-and-pillar mining method in which block and Sublevel are performed and ore removal is powered by blasting. This method greatly promotes stoping productivity, reduces dilution losses of ore, cuts mining cost, and is useful in mining thin dipping orebodies.
