Abstract
Mining geological environment evaluation is a complex systemic work. Influenced by lots of influence factors, there is not yet a uniform standard to make a scientific evaluation. Applying fuzzy mathematics model and degree of membership matrix in fuzzy evaluation, the Maoping Pb -Zn mine geological environment was divided to four ranks, excellence, good, medium and bad. The results provide a basis for the protection and restoration work. 23 evaluation factors as rock types, fault density, ditch the rail slope bed, joint develop degree, catchment area, collapse volume , land subsidence, groundwater levels fall, soil erosion, the pit number, the acreage of mining area, rainy season rainfall, vegetation coverage etc, was taken into account.关键词
