露天铁矿的穿孔工作量每年都有增加,目前它已达到1200万m/a。单位穿孔费用达到4～17卢布/m,个别露天矿的穿孔费用已占采矿总费用的20～30％。其原因是现有钻机的效率不高、钻具寿命低且费用高。因此,一些矿山企业(索科洛夫、萨尔拜、米哈伊洛夫和列别金等采选公司和其它一些企业)不得不进行对现有钻机的改造和新钻机的研制工作。本文作者在这方面做了多年的研究工作,并在研究结果中总结了在列别金、索科洛夫和萨尔拜露天矿的10、15和20 The perforation workload of open-pit mines is increasing every year and at present it has reached 12 million m / a. Perforation costs per unit reach 4 to 17 rubles / m, perforation costs of individual open-pit mines have accounted for 20 to 30% of the total cost of mining. The reason is that the existing drilling rig is not efficient, the drilling tool life is low and the cost is high. As a result, a number of mining enterprises (mining companies such as Sokolov, Saalbey, Mikhailov and Lebedin, and others) had to reform their existing rigs and develop new rigs. The author has done many years of research work in this area and summarized the results of the research on the 10, 15 and 20 of the Leipzig, Sokolov and Saar Bay open pit mines
