中文摘要：
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，结合焦作市住村矿相关数据，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。
英文摘要：
Coal resource is a exhaustible resource in the context of advocating sustainable developmet and recycling and low-carbon economy, the prime purpose of coal resource mining of enterprises is to improve the comprehensive efficiency of coal mining. Under such circumstances, the low-carbon economy is quite crucial for China＇s economic development. Improving the comprehensive efficiency of coal mining has been an issue regarding the sustainable development of economy. There are many factors joinly affecting the efficiency. The major factor affecting coal resource mining were analysized by investigating the characteristics of coal resources and coal mining in China. A practical comprehensive efficiency model of coal mining was structured. Data about coal mines in Jiaozuo City were used to calculate the actual comprehensive efficiency of the coal mines. An optimized combination of relevant factors were formed, which would be able to provide reference for reasaonble coal mining for coal enterprises in the future.
