长期以来,地下矿山的大部分采场曾都使用电耙出矿。自五十年代未期开始,气动装运机、柴油铲运机和振动出矿机相继问世,才改变电耙一统天下的局面。目前此三种出矿设备在我国金属矿山均有应用。为了正确选用出矿设备,更好地发挥每种设备的优点,本文拟对其合理的应用范围,进行粗略的划分。(一)三种出矿设备的比较电耙具有结构简单、设备牢靠、制造、维修和操作方便、价格低廉等优点,在崩矿量集中的电耙
For a long time, most of the underground mines had been powered by electric rakes. Since the late 1950s, pneumatic conveyers, diesel scrapers and vibrating mills have come into being one after another to change the situation of the electric rake. At present, these three kinds of mining equipment have applications in China’s metal mines. In order to properly use the ore-extracting equipment and give full play to the advantages of each equipment, this paper intends to make a rough division of its reasonable application range. (A) Comparison of three kinds of mining equipment Electric rake has the advantages of simple structure, solid equipment, easy manufacture, maintenance and operation, low price, etc.,
