东兰德公司金矿在斜井掘进中使用格莱达尔装岩机,可显著地降低掘进费用,这是斜井装岩的一个巨大进展。至今,东兰德公司各矿斜井平均每下掘0.3米约可排除20吨岩石。往靠近岩堆的倾斜箕斗中装岩已经很困难了,而且常常是在装箕斗前,不得不用人力多次扒集岩堆边远处的岩石。初步试验矿山管理部门对改进斜井掘进方法作了广泛试验研究后,决定采用格莱达尔装岩机。试验期间,曾用过履带翻斗式装岩机和沿斜井用绞车提升的轨行式装岩机。用这两种装岩机时,虽然铲斗装得很满,
The East Rand Goldfield uses Gledar rock loader in inclined shaft heading, which can significantly reduce the driving cost, which is a tremendous progress in inclined shaft rock loading. So far, the East Rand each inclined shaft mine average excavated 0.3 meters about 20 tons of rock can be excluded. It has been difficult to rock in sloping skipways near the rock mass, and it is often the case that the rock far away from the rock mass has to be scraped several times by manpower before loading the skip. Initial test The mine management department made a wide range of experimental studies on the improvement of the tunneling method and decided to adopt the Gledar rock loader. During the trial, crawler-mounted rock-fill rock-rigs and rail-mounted rock-rockers that were hoisted by inclined winches were used. With these two kinds of rock loader, although the bucket was loaded very full,
