伊敏露天矿端帮超前排土新技术的应用

Application of the end slope advance dumping new technology in Yimin Open-pit Mine

伊敏露天矿自2010年开始转向开采以来,转向进度较大,至2015年末共完成转向角度43°,平均转向进度8.6(°)/a,转向开采的转向中心轴在采区西侧,因此,西侧推进较慢,东侧推进速度较快。该方案充分降低了剥离生产成本,提高了设备的生产能力,这种高效的排土方式为其他露天矿提供了借鉴。

Yimin Open-pit Mine has turned to mining since 2010, the transition to exploitation is great. By the end of 2015, the mine has completed a total of 43°steering angle, the average to 8.6（°）/a in progress, the turning center is on the west side of the mining area. So the west side pushed slower and the east side pushed faster. This scheme reduces the cost of stripping production,improves the production capacity of the equipment, which provides a reference for other open-pit mines.
