Chon Of The Mabian P Mining And Dressing Project Environmental Quality Evaluation Studies

With the development of modern industry,the environmental pollution caused by construction project become more and more serious, it directly affects the developme- nt among economy and environment.

Therefore, how science and rational analysis on the mine environmental issues, is premise to prevent environmental problems.In the case study on Phosphorus mining project of Sichuan chemical works group in Mabian, there is an emphasis on evaluation of item regional environmental air and surface water quality application of fuzzy comprehensive evaluation method and index method. The result prove: air and water quality is good throughout the project area.Compared with the index evaluation method, fuzzy comprehensive evaluation method for dealing with the uncertainty and ambiguity is useful, it is a very good make up for the disadvantage index, and objectively reflect environmental status in phosphate rock district.Paper for government departments of supervision and management of the mining environment to provide reasonable basic data...
