Geological environment problems and countermeasures of Shijiaying mine in western Beijing

Abstract

Shijiaying, which is a small township in western Beijing, is rich in coal resources. Long-term coal mining has created enormous economic benefits, but also caused grievous geological environment problems, such as the deterioration of land resources and water resources, geologic hazards and the destruction of ecological landscape. Based on the analysis of the characteristics and hazards of the geological environment problems in mining area, we put forward a synthetic prevention scheme of the combination of engineering measures and biological measures. The engineering measures include slope cutting, earth-retaining and drainage works, and the biological measures are to green all available land with trees and grasses. After the countermeasures are taken, these hidden dangers will be cleared up to the utmost extent, and the ecological environment will be improved. Meanwhile, the economic development of local agricultural and forestry will be promoted. © 2011 Published by Elsevier Ltd.
