近年来由于生产费用增高且矿石产品价格下降,很多矿山被迫千方百计降低成本以自立于不败之地。采用坑内移动式破碎站并用带式运输机将矿石或废石运出坑外可降低运输成本。本文主要根据金属矿山的经验,论述采用这种方案对矿坑的几何参数、实际采剥比及对出入沟的要求等可能产生的影响以及与此方案有关的评价方法和总体概念。一般言之,带式运输机适用于将大宗物
In recent years, due to higher production costs and lower prices of ore products, many mines are forced to try their best to reduce costs to make themselves invincible. The use of mobile crushing stations in the pit and the use of belt conveyors to transport ore or waste out of the pit can reduce shipping costs. Based on the experience of metal mines, this paper discusses the possible impact of adopting this scheme on the geometrical parameters of mines, the actual mining ratio and the requirements of access and exit ditches, as well as the evaluation methods and overall concepts related to this program. In general, belt conveyors are suitable for bulk items
