Establishment and application of the environment evaluation model for beneficiation plant

Abstract

In order to evaluate the environment of beneficiation plant in a more scientific and reasonable way, this project took the workshop environment of beneficiation plant as the research object. This project divided the beneficiation plant into 7 evaluation units according to their functions. The evaluation indexes are dust, noise, light environment, microclimate, benzene, toluene and xylene. This project combined G1 method and entropy weight method to evaluate the weight of each evaluation index, the element extension model of the working environment of the concentrator is established by element analysis method, and the matter element analysis method is used to establish an evaluation index system of a beneficiation plant in East China. The results show that the evaluation level of the breaking workshop and the auxiliary facilities are unqualified, the auxiliary facility is qualified, the culling workshop, culled yard and accessory building are medium, the screening workshop and grinding workshop are good.
