Resources Environment in the Mining Area, Unascertained Measure, Analytic Hierarchy Process, Classification Weight, Confidence Recognition.Abstract
For safety evaluation of resources environment in the mining area, four aspects related to mining environment are discussed: landscape and relics destruction, mining resources destruction, water resources destruction and land resources destruction. Moreover, the safety index system of resources environment in the mining area is built and the evaluation is carried out based on unascertained measure model and analytic hierarchy process (AHP). First the judgment matrix is established using unascertained measure, and the weights are assigned to the indices by AHP. The safety level of resources and ecological environment in the mining area is evaluated by confidence recognition method. Finally a case study is carried out over a coal mine in Shaanxi Province, and the results show that the integration of unascertained measure and AHP is feasible for safety evaluation of resources and ecological environment in the mining area.
