为了改变我矿穿爆工作的落后面貌,我们单机组的全体同志和全矿职工一道,在武钢矿山研究室技术人员的配合下,从1965年9月开始,对露天潜孔钻机进行试验,结合我矿的生产实际,在吸取YQ-150A型潜孔钻机优点的基础上,革新成功了反修-170型风水混合湿式潜孔钻机。实践表叫,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YQ-150A型潜孔钻机相比,是一个突出的改
In order to change the backwardness of mine blasting work, all the comrades of our single crew and all the mine workers worked together with the technical staff of WISCO Mining Research Laboratory to start the test of the open-air and down-hole drilling rig since September 1965, I mine the actual production, drawing on the merits of YQ-150A DTH drilling rig, based on the successful renovation of the anti-repair -70 Feng Shui mixed wet DTH rig. Practice table is called, DTH drilling rig with perforation speed, you can play oblique hole, after blasting less large and bottom, after a small momentum, the advantages of a stable slope. Especially wet rock drilling, successfully solved the dust problem, compared with YQ-150A DTH drilling rig is a prominent change
