根据煤质指标对动力煤价格的影响,提出了平朔矿区商品煤价格分段线性计算模型,分析了灰分、硫分变化对商品煤价格的影响;提出了原煤理论价格概念和开采经济性的计算方法和模型,进而分析了原煤开采的理论利润和经济性等值线。根据对原煤开采经济性的计算,可以优化和指导开采计划安排。
According to the impact of coal quality index on the price of thermal coal, a piecewise linear calculation model was proposed for the price of commercial coal in Pingshuo Mining Area. The impact of the variation of ash content and sulfur content on the price of commercial coal was analyzed. The concept of coal price and the economical efficiency of mining Calculation method and model, and then analyzes the theoretical profit and economic contour of coal mining. Based on the calculation of coal mining economy, can optimize and guide the mining plan.
