梅山铁矿反修100潜孔钻机用于钻凿压顶、探矿、切割槽及天溜井中心孔等,更主要的是用于矿石裂隙较多处的补孔凿岩。由于矿体裂隙处易夹钎,致使电机负荷过载,加之电机被水淋受潮,因此电机烧坏严重。最严重的情况,有时打一个孔(孔深12～15米)就烧坏4～5个电机,严重地影响生产。遵照毛主席独立自主,自力更生的教导,在矿党委的领导和关怀下,我们“三结合”小组为解决反修100潜孔钻机的烧电机问题,对现有的反修100潜孔钻机进行了改进,采用叶片式风动马达(8马力)作回转动力,经过一年多的井下打眼,效果良好。在 f=14～16矿岩中,三台钻机平均台班效率为10米左右,最高达
Meishan iron ore anti-repair 100 DTH drilling rig used for drilling top pressure, prospecting, cutting slot and Tianying well center hole, the more important for the ore fissures more hole drilling. Cracks at the ore body easy to clamp brazing, resulting in overload motor load, combined with the motor water was wet damp, so severe motor burn. In the worst case, sometimes 4 to 5 motors are burned by punching one hole (hole depth 12 to 15 meters), seriously affecting the production. In accordance with Chairman Mao’s independent and self-reliance education, under the leadership and care of the coal party committee, our “three-in-one” team improved the existing anti-revision 100 DTH drilling rig in order to solve the problem of burning electric motors of anti-revision 100 DTH rigs , The use of vane wind motor (8 horsepower) for turning power, after more than a year of drilling the hole, the effect is good. In f = 14 ~ 16 rock, the average drilling rig efficiency of three rigs is about 10 meters, up to
