摘　　要：介绍了垂直分条堑沟式采矿法在枪马金矿的试验研究。实践表明 ,该采矿方法大大降低了采矿损失率和贫化率 。Experimental study on a method of dividing the ore body into vertical stripes and stoping the stripes by opening in Qiangma Gold Mine is introduced in this paper. Practice shows that this method has greatly reduced the rate of ore loss and dilution, and solved problems of stoping very thin gold orebody tilting at a small to medium slope angle.
