新城金矿矿岩破碎，开采技术条件复杂难度大（特别是矿体短），要达到设计生产能力，必须强化开采。为此，从国外引进了30多台先进的无轨采矿设备，以达到提高单位矿块面积内采矿强度和生产能力，提高劳动效率和降低作业成本的目的。目前在井下使用的无轨采矿设备达30台。其坑 Xincheng gold mine rock crushing, mining complex technical conditions difficult (especially the short ore body), to achieve the design and production capacity, we must strengthen the mining. To this end, more than 30 advanced trackless mining equipment have been imported from abroad in order to achieve the goal of improving mining intensity and production capacity per unit area of ​​nuggets, improving labor efficiency and reducing operating costs. There are currently 30 trackless mining equipment used underground. Its pit
