YQ-150A型潜孔钻机在f=6～10硬度的矿岩条件下穿孔,台年效率达66万吨,为冲击钻机的两倍;每吨矿岩的穿爆总成本降低15～20%;劳动生产率提高一倍以上;爆破质量大大改善,掌子后冲和根底基本消灭,对水平厚度7米以下的一级品薄层矿体可实行分级穿爆;钻机构造简单,工作性能 The YQ-150A DTH drilling machine is perforated at rock depth of f = 6-10 so that the annual efficiency can reach 660,000 tons, double the impact drilling rig. The total cost per ton of ore can be reduced by 15-20% ; Labor productivity more than doubled; blasting quality has been greatly improved, the back of the palm and the basic elimination of the basic level of 7 meters below the level of the first grade thin layer of ore body can be applied to wear a class; drilling machine structure is simple, working performance
