  • The mining of coal mine will inevitably disturb the water resources,ecological environment and geological structure around the mining area. At present,China has not formed an effective evaluation system and standard for the green development of coal water,so it is impossible to make a scientific and reasonable quantitative evaluation on the degree and effect of green mining of coal water. Firstly,based on the theory of "green mining in the whole life cycle of coal mine",the process of coal mining is divided into three stages:planning and design,construction and production,and closed pit restoration and treatment. Combined with the requirements of green mining in different stages,the stability of mining area system is taken as the benchmark,and the geological and environmental factors are comprehensively considered.The evaluation index system of coal water green mining degree in ecologically fragile area is established by analyzing the influence factors of mining,natural resources,ecological environment,geological disasters and social economy; Secondly,the gt-anp model is constructed by introducing graph theory and analytical network process,and the mixed weight is comprehensively analyzed by using "super matrix",and the coal mine is divided into four grades:unqualified,qualified,good and excellent. Taking Dahaize Coal Mine as an example,the scientific and reliability of the evaluation index system and evaluation method are verified. The evaluation results basically reflect the green mining degree of the mine,and provide the basis for the construction and comprehensive management of green mines.
