Abstract:
At present, China has not yet formed a systematic and effective evaluation system for the greenness of coal mining. How to scientifically and comprehensively evaluate the impact of intelligent coal mining on the greenness of coal mining has become an urgent problem to be solved. Based on the relevant literature research on the greenness of coal mining and related industry standards, this paper constructs an evaluation system for the greenness of coal mining by focusing on the mining methods, mining processes and mining impacts of coal mines, through expert questionnaire surveys and the analytic hierarchy process. It is believed that the greenness of coal mining is affected by four first-level indicators, namely resources, environment, safety and technology, and 21 second-level indicators. At the same time, the analytic hierarchy process is used to determine the evaluation weights of the greenness of coal mining, which to a certain extent avoids the influence of subjective factors and reduces the deviation of objective weights caused by large sample differences, thus making the final determined comprehensive weights more objective and reasonable. According to the evaluation weight results, improving the resource mining methods and the safety level of coal mines can greatly boost the greenness of coal mining.
