近十年来,由于采矿机械设备的发展,继掘进巷道采用机械切削代替爆破法之后,逐步扩展到在采场中试验无爆破采矿方法.这种采矿方法具有节省人力和材料;24小时可以连续进行采矿;能够获得较大的利润等优点,因此成为当前采矿方法研究课题之一.南
In the recent ten years, due to the development of mining machinery and equipment, following the mechanical excavation instead of blasting in the roadway for excavation, the blasting mining method has been gradually extended to test in the stope, which saves manpower and materials and can be continuously carried out in 24 hours Mining, the advantages of being able to gain large profits, etc. Therefore, it has become one of the research topics of the current mining methods.
