Comprehensive Efficiency Models of Coal Mining and Its Applicntion
煤炭开采综合效益模型及其应用

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.
