Abstract:
In order to study the characteristics of coal resources of Luning Coal Industry Group, through literature research and on-site investigation, this paper analyzes the four aspects of resource conditions, safety and mining technical conditions, environmental conditions and economic benefits, and establishes a comprehensive evaluation index system for coal resources of Luning Coal Industry Group.Using analytic hierarchy process (AHP) to calculate the weight of 24 evaluation indicators in the comprehensive evaluation index system of coal resources, using the entropy method to correct the weight of the indicators, and obtain the comprehensive weight of each evaluation index, comprehensive evaluation of coal resources of each branch of Luning Coal Industry Group.The results show that the comprehensive evaluation grade of coal resources of Zhongdahangou Coal Industry of each branch of Luning Coal Industry Group is good.The comprehensive evaluation grades of coal resources of Qianjiang Coal Industry, Qifeng Coal Industry and Jing’an Coal Industry are middle, However, the average score of comprehensive evaluation of coal resources is 47.805 4, which indicates that the score is lower, and the overall deviation of coal resources of Luning Coal Industry Group.Based on the assessment results and on-site investigations, we will provide targeted recommendations for the development of Luning Coal Industry Group.
