矿山是耗能的大户之一,特别是露天矿山开采量大,运输距离长,耗能就更多。一般来讲露天矿山内部矿岩运输能耗约占整个矿山(除外部运输和选矿)能耗的1/4～1/3。因此能否选择合理的开拓运输方案,对露天矿山运输的节能意义很大。本文拟以江苏四个冶金辅助原料矿山为例,浅谈山坡露天矿应用平硐溜井开拓运输的节能效果。一、江苏四个冶金辅助原料矿山的基本情况船山石灰石矿系浅海相形成的石灰岩,矿体主要由黄龙群灰岩,船山群灰岩和栖霞组臭灰
Mine is one of the major energy-consuming, especially open-pit mines mining large transport distance, energy consumption more. Generally speaking, the energy consumption of ore transportation within the open pit mine accounts for about 1/4 to 1/3 of the energy consumption of the entire mine (excluding external transportation and beneficiation). Therefore, it is of great significance to choose a reasonable scheme for developing transportation and save energy for open-pit mines. In this paper, we will take the four metallurgical auxiliary raw materials mines in Jiangsu as an example to discuss the energy saving effect of the open pit transportation in the hillside open pit mine. First, the basic situation of four metallurgical auxiliary material mines in Jiangsu Limestone limestone mines formed by the shallow sea facies of Chuanshan limestone, the orebodies are mainly composed of Huanglong group limestone, Chuanshan group limestone and Qixia group
