元宝山露天矿合理优化工作线长度的研究
首发时间:2019-07-19
摘要:露天矿工作线长度是露天煤矿重要的开采参数之一,工作线长度影响着开采工程中所产生的采剥和运输费用等成本的支出,因此合理的工作线长度影响着煤矿企业的经济发展,本文以元宝山露天煤矿半连续工艺实际现场案例为出发点,结合元宝山露天煤矿年生产能力由800Mt/a核增至1200Mt/a,研究分析合理优化工作线长度,得出与其生产能力相匹配的合理工作线长度,用以提升露天煤矿企业的经济效益。

Study on Reasonable Optimizing Working Line Length in Yuanbaoshan Open-pit Mine
Abstract:The length of working line in open pit mine is one of the important mining parameters of open pit mine. The length of working line affects the cost of mining, stripping and transportation in mining engineering. Therefore, the reasonable length of working line affects the economic development of coal mining enterprises. This paper takes the actual semi-continuous process of Yuanbaoshan open pit mine as an example. Starting point, combined with the annual production capacity of Yuanbaoshan Open-pit Coal Mine increased from 800 Mt/a to 1200 Mt/a, the reasonable length of working line was studied and analyzed, and the reasonable length of working line matched with its production capacity was obtained, so as to enhance the economic benefits of open-pit coal mine enterprises.
Keywords: Open-pit mine Working line length Reasonable optimization Economic benefit
