根据预测估计,在开采深度不断加大的条件下,继续采用钢绳提升设备,矿山巳达到的生产能力只能维持到1990年,此后,生产能力将开始下降。因此,在要求降低每吨矿石提升成本的同时,解决矿山深部开采的保产问题,及研制深井新式提升设备问题,已成为最重要的课题。为保证提升设备的生产能力随深度的增大而提高,只能依靠加大容器的载重量。因此,多绳提升设备获得了广泛的应用。但是,加大多绳提升设备箕斗的载重量受到极 According to the forecast, with the continuous increase of mining depth, the steel rope hoisting equipment will continue to be used, and the mine’s production capacity can only be maintained till 1990, after which the production capacity will start to decline. Therefore, it is the most important issue to solve the problem of preserving the production of deep mining in the mine and to develop the new type of lifting equipment for deep well while reducing the cost of raising ore per ton. In order to ensure that the production capacity of the upgrading equipment increases with depth, the loading capacity of the container can only be increased. Therefore, multi-rope lifting equipment has been widely used. However, the load on the skip with additional hoisting equipment has been extremely high
