有色金属矿山,当日产量超过1000T/日,竖井深度大于300米时,往往采用箕斗提升。单绳提升的金属矿山中,大多采用翻转式箕斗;多绳提升的金属矿山中,广泛采用底卸式箕斗。少数矿山中,也有将底卸式箕斗用于单绳提升,翻转式箕斗用于多绳提升的。箕斗是现代矿井的主要提升容器,因此,矿石块度与箕斗关系的认识深化,对箕斗设计和矿山生产都有一定的实际意义。
Non-ferrous metal mines, the daily output of more than 1000T / day, shaft depth greater than 300 meters, often using skip upgrade. Among the metal mines with single ropes, flip-type skip is mostly used; in the multi-rope-lifted metal mines, the bottom-loading skip is widely used. A small number of mines, there are also at the end of dumping skip for a single rope lift, flip skip for multi-rope lift. Skips are the major containers for modern mines. Therefore, the deepening understanding of the relationship between ore block and skip has some practical significance for the design of skip and mine production.
