平朔矿区经30 a开发后,出现了生产成本高、征地困难、过小煤窑采空区、新技术应用等诸多问题。通过对东露天矿和安太堡露天矿采剥现状分析,就两矿矿界调整、采区互换、工作线长度优化等问题进行了研究,并对矿界方案进行了优化,有效确保了两矿未来稳定、高效、低成本开采。 After the development of Pingshuo Mining Area for 30 years, many problems such as high production cost, difficulties in land acquisition, goaf over small coal mines and the application of new technologies have emerged. Based on the analysis of the status quo of the open pit mining in the East and Antaibao open-pit mines, the paper studied on the adjustment of the mining industry in both mines, the exchange of mining areas and the optimization of the working line length. The mine plan was optimized to effectively ensure Two mines in the future stable, efficient and low-cost mining.
