武钢大冶铁矿东露天矿,在工人、干部、技术人员的配合下,结合矿山生产实际,在汲取YQ—150A型潜孔钻机优点的基础上,对露天矿潜孔钻机进行试验研究,革新研制成反修—170型风水混合湿式潜孔钻机。实践表明,反修—170型潜孔钻机具有穿孔速度快,可以打斜孔,爆破后大块和根底少,后冲力小,对稳定露天矿边坡有利等优点。特别是湿式凿岩,成功地解决了粉尘问题,与
With the cooperation of workers, cadres and technicians, combined with the actual mine production, on the basis of absorbing the merits of YQ-150A DTH drilling rig, the open pit mine of WISCO Daye Iron Mine is experimentally researched and innovated Developed anti-repair -70 Feng Shui mixed wet DTH drill. Practice shows that anti-revision -170 DTH drilling rig has the advantages of fast perforating, slanting holes, less bulk and bottom after blasting, small after-impact and favorable slope for stable open pit mine. Especially wet rock drilling, successfully solved the dust problem, and
