The Study On Geological Environment Of Sitai Coal Mine

This paper takes Sitai mine as a research area, fully collected the geological environmental information of Sitai mine by the ways of collecting the previous geological information and making field survey etc. based on which summarized the current mainly geological environmental problems and the features. Aiming at the current mainly geological environmental problems and the features of Sitai coal mine, use analytic hierarchy process combines the fuzzy evaluation method, build evaluation index system and calculate evaluation index weight, comprehensive evaluate the mine geological environmental information of Sitai coal mine, conclude the evaluation result of the of Sitai coal mine is grade Ⅲ(serious), use the method of compare the qualitative and quantitative evaluation result, verified the evaluation result is correct. According to the evaluation result, divide the research area of Sitai coal mine into mine geological environmental key prevention(Ⅰ) and mine geological environmental sub-key prevention(Ⅱ). The industrial fields, villages, rivers gangue hills and highways etc. in the research area which cover an area of 1.87km2 are key prevention. Aiming at the current problem of mine geological environmental of the research area, propose reasonable prevention methods.
