国家重点科技攻关项目12—20m~2全液压钻装锚机组通过第一阶段的试验,现经修改设计和改制,将于1991年7月底前完成样机出厂。该机采用两台液压凿岩机同时钻眼,凿速1.5m/min左右;装载能力60m~3/h以上;轨轮行走,轨距900mm;最佳适用断面16m~2左右,国家合同要求月进尺80m以上。因原试验点已无岩巷可掘,决定另找试验
National key scientific and technological project 12-20m 2 full hydraulic drilling anchor unit passed the first phase of the test, is modified design and restructuring, will be completed before the end of July 1991 prototype. The machine uses two hydraulic rock drill drilling at the same time, chisel speed 1.5m / min or so; loading capacity of 60m ~ 3 / h or more; rail wheel walking, gauge 900mm; the best section about 16m ~ 2, 80m above. Due to the original test point no rock can dig, decided to find another test
