平朔安太堡露天矿背斜东翼开拓延深工作线长度优化

Optimization of anticline east wing extended working line length in Pingshuo Antaibao Open-pit Mine

针对安太堡露天矿背斜东翼开拓延深,剥采比逐渐增大,顺坡内排无法跟进,内排空间不足,外排运输距离远,提升高度大,设备效率难以发挥,向下延深露煤困难,生产成本高、经济效益差等问题,对背斜东翼开拓延深工作线长度进行合理优化。

According to the anticline east wing development deepening, the stripping ratio increases, the slope internal dumping cannot follow, lack of internal dumping space, external dumping transport distance is far, large lifting height, it is difficult to play equipment efficiency, downward extension of the deep mining is difficult, production cost is high, economic benefit is poor. The mine reasonably optimizes the anticline developing work line length.
