本文通过研究我国煤炭资源的特点及开采的概括,分析得出影响我国煤炭资源开采的主要因素,构建了具有应用价值的煤炭开采综合效益模型。运用DPSv7.5.5软件,结合焦作市位村矿相关数据,计算出各年份该矿的实际综合效益,并对影响煤炭资源开采回采率的要素对回采率的影响程度进行确定,得出相关要素的最优组合。为今后煤矿企业的科学开采提供参考。对于煤炭资源开采综合效益的提高,合理的要素投入组合的选择,实现煤炭资源开采综合效益最大化,其研究结论具有重要的意义。
By studying the characteristics of coal resources in our country and the generalizations of mining, the paper analyzes the main factors affecting the exploitation of coal resources in our country and constructs a comprehensive benefit model of coal mining with application value. Using DPSv7.5.5 software, combined with the relevant data of Jiaozuo City Village Mine, calculate the actual comprehensive benefit of the mine in each year, and determine the impact degree of the factors affecting the recovery rate of coal mining recovery factors, and draw the relevant factors Optimal combination. For the future coal mining enterprises to provide scientific reference. It is of great significance for the improvement of the comprehensive benefits of coal resources exploitation, the selection of rational factors into the portfolio, and the maximization of the comprehensive benefits of coal resource exploitation.
