英古列茨采选公司露天矿的特点是,矿山地质和水文地质条件复杂。开采初期,曾采用БС-1M 钢绳冲击钻穿孔。尽管这种钻机的技术可行性没有问题,但不能满足大量矿岩准备的要求,因此必须用比较现代化的、生产能力高的凿岩设备来代替。1965年试用过СБО-160/20火钻,但其合理应用范围极为有限,故1971年停止使用。1966年开始试用СБШ-250牙轮钻机,这种钻机是供在 f=10～16的岩石中钻凿炮
The characteristics of the Angulit mining company’s opencast mine are the complex geological and hydrogeological conditions of the mine. Early mining, has used БС-1M steel wire percussion drill perforation. Although this rig is technically feasible, it does not meet the demands of a large number of rock preparations and must therefore be replaced by more modern, high-productivity rock drilling rigs. 1965 trial СБО-160/20 fire drill, but its application is extremely limited range, it was discontinued in 1971. The trial of the СБШ-250 roller cone rig, started in 1966, is for drilling guns in f = 10 to 16 rocks
