Fuzzy Appraising of Mining Geological Environment

There are many of factors affecting the mining geological environment. Traditional valuation is based on qualitative analysis and judgment of specialists. Doing by this, there are different results about the same mining geological environment only because of different experts. In this paper, in view of the characteristic about mining geological environment, the norms relating resource destroy, geological damage and environmental pollution are set up to reflect the situation about mining geological environment. The authors have adopted the appraising method based on fuzzy mathematics to sort and determine the rank of all the appraising objects in order to provide scientific foundation for the investigation and valuation of mining geological environment and the improvement of mining ecological environment. Utilize geological development intensity of calamity can test appraise result. To mine area, wash itch and topography steep district, its credit rating is generally IV and V grade, generally all fall into relatively bad district. So the method has a relatively high confidence degree on appraise.
