露天煤矿合理工作线长度确定

Determining of reasonable working bench length in Open-pit Coal Mine

为探求露天煤矿合理的工作线长度,对影响工作线长度的几个主要因素进行分析,最终通过函数模型及净现值NVP值综合分析工作线长度对采、运、排影响,从而确定露天煤矿的最佳工作线长度。

To explore the reasonable length of working bench of the open-pit coal mine, the article analyzes several main factors of affecting the working bench length. Finally through function model and NVP, the author comprehensively analyzes the effects of the working bench on mining, transporting and dumping, and determines the reasonable length of working bench of the open-pit coal mine.
