中间搭桥技术在哈尔乌素露天煤矿的应用
Application of Pit-middle Bridging Technology in Haerwusu Surface Coal Mine
摘要
Abstract
In order to solve the problem that the inner-dump transport distance increases due to the steep mining is cancelled in the lower end-slope road at the bottom of Haerwusu Surface Mine,the pit-middle bridging technology is adopted to connect the lower transport road at the bottom.According to technical scheme of pit-middle bridging technology,the calculation model of transport distance and transportation cost is established.The pit-middle bridging technology is applied in Haerwusu Surface Mine and its economic benefits are checked.The results show that pit-middle single bridging scheme can save transportation costs by 29.1％,and the pit-middle double bridging scheme can save transportation costs by 23.4％.Therefore pit-middle single bridging technical scheme is recommended.关键词
