一、概述 一九八六年十月二十日至二十四日,冶金工业部和机械工业部联合在南昌市召开了露天矿穿孔工艺和穿孔设备技术信息交流会。这是近几年来一次比较大型的全国性专业技术会议。与会代表二百一十多人。 六十年代及七十年代初期,我国金属露天矿穿孔设备普遍采用冲击式钻机,少数矿山使用潜孔钻。设备性能差,效率低,工艺非常落后,穿孔爆破工作成为我国露天矿山生 I. Overview From October 20 to October 24, 1986, the Ministry of Metallurgical Industry and the Ministry of Machinery Industry jointly held a seminar on technical information on perforation and perforation equipment for open-pit mines in Nanchang. This is a relatively large-scale national professional and technical conference in recent years. More than 210 delegates attended the conference. In the 1960s and early 1970s, percussive drilling rigs were widely used in the perforation equipment of the metal surface mine in our country, while the drills were drilled in a few mines. Equipment performance is poor, low efficiency, technology is very backward, perforation blasting work to become China’s open-pit miner
