Study and Entironmental Impact Evaluation on an Expanding Project of Coal Mine

To asses entironmental feasibility of Expanding and Improving Project on Xihe Coal Mine (EIPXCM) and predict it's influence on entironment, according to related regulations and technical features of the project, prediction models and parameters of surface movement and deformation were determined. Its influence evaluation was down. The results shows that the largest value of ground subsidence in whole mine field is 1.219 m, and corresponding affected scope of surface movement and deformation is 42673 m(2). Then the appraisals of entironmental impact on land sink, soil erosion, land occupation, biomass loss, wild animals and landscape ecology were done. The results indicates that only a little land occupied, there will not be big change on regional landscape situation and the project will affect ecosystem very little. Finally, relieving measures of entironmental influence were proponed. Therefore, on the conditions of taking proponed measures, this project is feasible from the point of view of entironment.
