摘　　要：从卡车运输能力、矿山物料条件以及系统可用度3个方面对半连续工艺系统的生产能力进行了分析,建立了半连续工艺系统运行边界条件、效益边界条件以及最低规模边界条件模型,并实证分析了黑岱沟露天煤矿上部剥离台阶半连续工艺系统应用的边界条件.研究表明,黑岱沟露天煤矿160 m深度以上剥离台阶采用半连续工艺是合理的,剥离运营费用可降低21.27%,总剥离费用可降低11.83%,且具有一定的抗风险能力.After analyzing the influence of truck fleet capacity, material handhng conditions, and system availability on the production capacity of semi-continuous mining system. The boundary conditions of semi-continuous mining system, system efficiency and system scrapping are built, and the boundary conditions of semi-continuous mining system for upper stripping benches in Heidaigou surface coal mine are analyzed as an example. Results show that the operation cost and total stripping cost can be reduced by 21.27% and 11.83%, respectively, and the system risk is reduced too. The application of semi-continuous system on the upper 160 m stripping benches is reasonable in Heidaigou surface coal mine.
