安太堡露天煤矿过背斜区开采程序优化

Optimization of mining program in over-anticline area of Antaibao Open-pit Coal Mine

为了解决安太堡露天矿过背斜区开采程序优化问题,在分析背斜构造对开采程序的影响基础上,提出过背斜超前开采方案、纵采方案和伪纵采方案3种不同的开采程序方案,并通过分析生产剥采比、运距、提升高度等指标的变化规律,对所提出的3种备选方案进行优化对比。经对比北部超前开采方案生产剥采比及剥离运距均小于纵采及伪纵采方案,故推荐采用北部超前开采方案为过安太堡露天煤矿过背斜开采程序方案。

In order to solve the optimization problem of the mining program during the anticline area of Antaibao Open-pit Mine,on the basis of analyzing the influence of the anticline structure on the mining program,the article presents an anticline advanced mining scheme,a longitudinal mining scheme and a pseudo-longitudinal mining scheme.By analyzing the variation law of economic indicators such as production stripping ratio,transportation distance and lifting height,the article optimizes and compares three proposed alternatives.The distance is smaller than the longitudinal mining and pseudo-longitudinal mining schemes,so it is recommended to adopt the northern advanced mining scheme as the over-anticline mining procedure scheme in Antaibao Open-pit Coal Mine.
