摘　　要：地下金属矿山生产能力和采矿凿岩作业关系密切相关。为了提高矿山生产能力,进而提高矿山经济效益,对影响矿山生产能力的凿岩作业效率、凿岩作业精度、凿岩作业深度、爆破作业后的爆破效果等相关问题进行研究,分析了矿山在使用YGZ90钻机、QZG80A潜孔钻机、采矿凿岩台车过程中遇到的问题和各自的优缺点,针对不同岩性、不同深度钻孔在凿岩作业过程中各自的作业特点,通过现场试验获取了相关试验数据,对试验数据进行对比分析,得出影响地下矿山采矿生产能力的关键因素主要有爆破方式、生产设备(凿岩设备)、提升运输方式等;提出了解决制约这些因素的方法或加以改进的有效路径,最终得到提升矿山生产能力的有效途径是改进凿岩设备,使矿山生产能力大幅度提升,达到了提高矿山经济效益的目的。The production capacity of underground metal mines is closely related to the drilling in mining operations.In order to improve mine production capacity and economic benefits of mine,such issues as drilling efficiency,drilling preci- sion,drilling depth that affect the production capacity of the mine,and blasting effect after operation are investigated.The problems in application of YGZ90drill,QZG80A DTH drill,jumbo in the mine,and their advantages and disadvantages are described,and the characteristics of drilling with different lithology and different depth are respectively demonstrated.The re- lated test data are obtained through field test.After contrasting the test data,the key factors influencing the mine production capacity are explored,including blasting mode,production devices (drilling),hoisting and transporting way;Through analy- sis on these key factors,the solution to restrict these factors or the effective improvement are put forward.Finally,the effec- tive ways to improve the mine production capacity is to modify the drilling devices,which can significantly enhance the mine production capacity,and increase the economic benefit.
