The energy source base is located in the contiguous area of northwest of Shanxi,north Shaanxi and south of Inner Mongolia,covering
48,800 sq. km. The coal reserves account for 1/3 of China's, and this region will be the main area of energy resources in next century in China. Since 1986, construction in mining area has made a great progress. A fotlndation ofmoderlized coal mining area has been formed. Nevertheless, because of lower
developing of local social economy base and very fragile ecological system, intensive impacts of mining/construction actlveties have brought out some environmental problems .incltlding: 1) Agravating man ─made soil erosion and bringing out some new problems of
environment; 2) Silting up river channals and reducing capacity of flood passing sharply; 3) Destroying and polluting water and air resources; 4) Land and vegetatioo resources degradation. As a result, the problems of environment have become the priority of coal mining and sustained developing.In this paper the effects of mining activeties on environment are analysed generally. In brief,coal mining has brought a great promotion to the local economy and produced some severe environment probelms. Some measures of environment care have been taken and the benefits are remarkable. In order to make a good coordination of coal mining and environment renovation, the following projects have been proposed based on the investigation. Establishment of environmental monitoring network and the pre ─ warning information system; strengthening controlling of soil erosion and land desertification;developing and extending technologies of environment renovation;and establishing some experimental and demonstrative areas.
