THE MAIN HYDRO-ENGINEERING-ENVIRONMENTAL-GEOLOGICAL PROBLEMS AROSE FROM THE EXPLOITATION OF COAL RESOURCE IN YU-SHEN-FU MINE AREA OF NORTHERN SHANXI AND THEIR PREVENTION MEASURES

WT5,5BZThe main hydro engineering environmental geologicalproblems arisen from the exploitation of coal resource in Yu shen fu Mine Area are analyzed. Based on the study the hydro engineering geological conditions, the results of desertification, soil and water erosion, water environment which will be affected by the coal mining in future in Yu shen fu Mine Area are predicted. Some technical methods and engineering measures for preserving water resource and undertaking coal mining are suggested in the paper.
