摘　　要：针对矿山传统底部结构存在的作业安全风险性大、出矿卡漏现象严重等问题,进行了"V"型堑沟改造试验。试验结果表明,"V"型堑沟受矿可明显提高矿山生产作业的安全性和出矿效率,采场生产能力由160t/d提高到210t/d,明显增加矿山经济效益。There are some problems of traditional bottom non of ore drawing leakage and so on. In view of these structure in a mine, such as poor working security, serious phenomeproblems, the experimental researches on the transformation of V- shaped trench were carried out. The optimization results showed that working security and mining efficiency of V-shaped trench were improved obviously. Meanwhile, the stope production could reach to 210 tons per day, which had significant meaning to improve economic efficiency.
