【摘要】：基于经济合理剥采比准则以及地表模型和柱状煤层模型,应用CoalDesign软件系统对内蒙古某露天煤矿进行最终境界设计,得出了不同经济技术条件下的最终境界的形态.分析讨论了最终境界随成本价格变化的情况.实践表明,以当前技术经济参数为基准,原煤价格上升10%,原煤开采量增加7.9%,岩石剥离量增加11.5%,第四纪层剥离量增加6%,境界总体积增大9.5%,不考虑基建投资,利润值增加238%;开采成本降低10%,原煤开采量增加8.4%,岩石剥离量增加12.3%,第四纪层剥离量增加6.5%,境界总体积增大10.2%,不考虑基建投资,利润值增加245%.可以看出最终境界对成本价格的灵敏度很高,境界分析对矿山生产决策者做出正确决定有重要的参考价值.
[Abstract]:Based on the economic and reasonable stripping ratio criterion, surface model and columnar coal seam model, the final boundary design of an open pit coal mine in Inner Mongolia is carried out by using CoalDesign software system, and the final boundary shape under different economic and technological conditions is obtained. The change of the final boundary with the cost and price is analyzed and discussed. Practice shows that, based on the current technical and economic parameters, the price of raw coal rises by 10 percent, the amount of raw coal extraction increases by 7.9 percent, the amount of rock stripping increases by 11.5. the amount of Quaternary layer stripping increases by six, and the total boundary volume increases by 9.5 percent, regardless of capital construction investment. The profit value is increased by 238.The cost of mining is reduced by 10 percent, the amount of raw coal is increased by 8.4, the amount of rock stripped is increased by 12.3am, the amount of Quaternary layer is increased by 6.5 and the total volume of boundary is increased by 10.2.The profit value increases by 245without considering the capital construction investment. It can be seen that the sensitivity of the final boundary to the cost and price is very high, and the boundary analysis has an important reference value for the decision makers of mine production.
