别斯库都克露天煤矿降低剥采比的措施

Measures of reducing stripping ratio in Biesikuduke Open-pit Coal Mine

别斯库都克露天煤矿降低生产剥采比的措施提出远期与近期2种规划.结合露天矿境界形态,远期规划通过比较经济合理的开采深度,圈定分期境界.近期方案采用靠界开采和提前坑内回填等措施进而调整生产剥采比降低成本。

The measures of reducing the production stripping ratio is to propose two kinds plans of long-term and short term.Combining the open-pit vision form, the long-term plan delineates the boundary of stages by rational mining depth.The short-term scheme adopts boundary mining and advancing backfill to adjust production stripping ratio to reduce production cost.
