内排条件下露天矿剥离半连续工艺应用范围研究
Study on application scope of stripping semi-continuous system in internal dumping open pit mine
摘要
Abstract
Based on the analysis of overburden internal dumping distance in the open pit mine, this ar-ticle establishes the optimization model of mining system, and provides support for the research on ap-plication scope optimization of stripping semi-continuous system. According to the characteristics of flat dipping open-pit mining, this article gives the calculation methods of overburden internal dumping distance in the shovel-truck discontinuous system and semi-continuous system. Based on comprehen-sive consideration of investment and operation cost effect, open pit mining system optimization model is established with the objective of minimum total cost in calculation period, and gives the calculation method of investment, stripping system operation cost and the additional costs, and the boundary condi-tions of semi-continuous application. The case study shows that with the increasing of mining depth and pit size, the application of semi-continuous system in upper stripping bench is reasonable, and the ser-vice range of the stripping semi-continuous system in H Mine is more than +140m level. Sensitivity analysis of fuel costs shows that the rapid rise of diesel prices in China will popularize the application of stripping semi-continuous system in large open pit coal mine.关键词
