用移动坑线开拓的铁道运输工艺露天矿其工作帮由采掘平盘和运输平盘的台阶所构成。两种平盘的宽度决定了工作帮坡角和生产剥采比。在两种平盘的组成要素中,除移动坑线的移设宽度外,均由采矿、运输设备及设施的技术规格,工艺参数及安全因素所决定,只有移动坑线的移设宽度有较大的灵活性。故本文对移动坑线经济合理的移设宽度加以探讨。
Open Pit with Mobile Pit Line Open Pit Operations Its work is supported by the steps of the excavation flat and the transport flat. The width of the two flat-panel determines the work slope angle and production stripping ratio. Among the components of the two flat plates, except for the shift width of the moving pit lines, they are determined by the technical specifications, process parameters and safety factors of the mining and transportation equipment and facilities. Only the moving pit lines have a greater width Great flexibility. Therefore, this paper discusses the economic and reasonable transfer width of mobile pit line.
