我矿小钻机担负着全矿找煤、定构造、探老窑、探放水和灭火等任务。由于生产钻都在井下施工,条件差,要求钻机体积小、重量轻、力量大。原200米、50米钻机的缺点是:体积大,部件多,笨重,搬运安装困难,工人的劳动强度大。每打一个钻孔都要掘4～5米长的钻窝,往往不能如期施工。因此钻探工作一直很被动。 I mine a small rig bearing the whole coal looking for coal, will structure, exploration of old kilns, exploration and release of fire and other tasks. As the production of drilling are in the underground construction, poor conditions, require rigs small size, light weight, great power. The original 200 meters, 50 meters rig shortcomings are: bulky, multi-component, bulky, handling and installation difficulties, labor-intensive workers. Every drill a hole to dig 4 to 5 meters long drill hole, often can not be expected construction. That’s why drilling has always been passive.
