摘要
针对大宝坡石灰石矿开采过程中非冶金石灰岩资源大量出露问题,对其回收利用方案进行了分析,确定了该矿400 m水平以上非冶金用石灰石的经济合理剥采比,解决了生产现场由于生产剥采比的最优化和均衡之间不协调的矛盾,开辟了矿山循环经济发展的新思路,可供类似矿山参考。
The non-metallurgical limestone resources is exposed in large scale during the mining process of Dabaopo Mine in Chongqing City, in order to improve the resource utilization rate, the recycling scheme of the non-metallurgical limestone is proposed. The economic and rationality stripping ratio of the non-metallurgical limestone above 400 m level of the mine is determined, the incongruous contradiction of the optimization and equalization of production stripping ratio of the mine is solved, the new ideal of mine circular economy development is proposed, which can provide reference for the other mines.
