为了落实毛主席关于“开发矿业”的伟大指示,迅速扭转矿山穿凿作业的落后面貌,我们在各兄弟单位的大力协助下,结合南芬露天矿的具体条件,试制成功南芬200型潜孔钻机,即1号钻机;在此基础上,于1970年6月试制出2号钻机,1972年初又改进试制出3号钻机。1号和2号钻机经试验后,于1971年4月正式移交生产,3号钻机于1972年3月进行工业试验。至1972年8月底,三台钻机共钻凿炮孔36904米(矿石孔6363米,岩石孔30541米),爆破总量281.7万吨(矿石58.7万吨,岩石223万吨)。三台钻机均已连续运
In order to implement Chairman Mao's great instructions on “developing the mining industry” and quickly reverse the backwardness of the mining operations, we tried out the successful Nanfen 200 DTH drilling rig with the help of the brothers and with the specific conditions of the Nanfen open-pit mine , That is, Drill No. 1; on this basis, trial production of Drill No. 2 in June 1970 and trial production of Drill No. 3 in early 1972. After the test of No. 1 and No. 2 rigs, they were formally handed over to production in April 1971, and No. 3 rig was tested in March 1972 for industrial tests. By the end of August 1972, the three drilling rigs drilled a total of 36,904 meters of blast holes (6,363 meters of ore holes and 30,041 meters of rock holes), with a total volume of 2,177,000 tons (587,000 tons of ore and 2,223,000 tons of rock) blasting. Three rigs have been shipped continuously
