Research On Green Mine Evaluation Index System Of Underground Mining

The concept and practice of green ecological was went through the wholeprocess of the mineral resources exploration and utilization in green mines，whosettled the goal of protecting the ecological environment, reducing resourceconsumption, pursuing of recycling economy. As the development trend of futuremining, the vigorously advocate and support were obtained from the government,society, etc.In our country, account of about90%of the coal production was produced by theunderground mining, which had an important position in coal mining. But the greenmines of underground mining were too little to the whole. There was a trend to gainthe proportion of the green mines of underground mining, so it has a vital significanceto structure the scientific and reasonable evaluation index system of green mines ofunderground mining.Due to the important significance of evaluation researching of the green mines ofunderground mining, the contents below were included in this thesis. Firstly, with thefundamental meaning of green mines, advanced techniques in green minesconstruction, reference researches and the production characters of undergroundmining, the green mines of underground mining evaluation index system wasestablished. Secondly, on weight conforming, membership degree, non-membershipdegree and hesitation degree were introduced based on interval valued intuitionisticfuzzy set to describe fuzziness vividly. It made the result more scientific by using theinterval valued intuitionistic fuzzy entropy. Thirdly, As the fuzziness anduncertainties of data, the improved Gray clustering was used to make sure the data’smembership, corporate with the index weight, clustering coefficient was calculated.The whole mines level can be conformed as the maximum principle. At last, aninstance was illustrated by Ping Dingshan fourth mine to verify the reasonable ofindex and the feasibility of theory. Some advices were put forward to make it better.
