Abstract: This paper established the evaluation index system and evaluation model of nonmetal mine geology environment in Xinjiang which combined with Xinjiang non-metallic mine geological features and in consideration of the influence of mine geological environment impact evaluation factors.The evaluation index system was composited of the mining exploitation caused or aggravated by geological disasters scale, geological disasters of the threat to personnel quantity, mine facilities dug loss or pressure the total destruction of land ground leading slope, dig the maximum loss in depth or pressure accumulation maximum height, dug loss volume or bulk volume and the area of damaged land.Based on 72 evaluation units of 11 mines in Xinjiang area as learning samples, the evaluation model of nonmetal mine geology environment was established, and the model was tested by the method of return generation, and the correct rate was 98.6%.The evaluation model is applied to the granite mine of Hami city, Xinjiang, and the 9 evaluation units of the mine are analyzed and evaluated, and the result is satisfactory.The evaluation index system and model have a certain reference value for the assessment of the impact degree of nonmetallic mine geological environment in Xinjiang area.
