可钻4(1/2)～8英寸直径深孔的潜孔钻机从七十年代初用于地下采矿作业以来,已给矿山设计人员增加了一种在采场设计上可供选用的有效的回采技术。这种钻机在全世界的大型和小型矿山中得到应用,用于深孔崩矿空场法、垂直漏斗后退式采矿法、阶段房柱法和矿柱回采以及其他用途。 1973年,一台潜孔钻机在铜崖北(Copper Cliff North)矿进行试验。这时,国际镍业公司(Inco)在安大略省萨德伯里矿区的镍矿是首先认识到使用这种钻机可降低开采成本的矿山。在两年内,国际镍业公司在萨德伯里矿区的12个矿山已有18台潜孔钻 Downhole drilling rigs capable of drilling 4 (1/2) to 8 inch deep holes have been used by miners since the early 1970s for underground mining operations, and have added to mine designers an effective Mining technology. The drill rig is used in large and small mines around the world for deep-hole collapse minefields, vertical funnel retraction mining, staged and pillar mining, and other uses. In 1973, a DTH drill was tested at the Copper Cliff North mine. At this time, Inco’s nickel mine in Sudbury, Ontario, was the first to recognize the mine that used the rig to reduce mining costs. Within two years, Nickel International has 18 DTH drilling rigs at 12 mines in the Sudbury mine
