According to the sevious newly-increased soil and water loss caused by the mining exploitation in the Shenfu-Dongsheng coal mining area,the effects of different underlying surfaces including undisturbed soil,disturbed soil and earth road on runoff generation and sediment yield in Shenfu-Dongsheng coal mining area together with their reasons or mechanisms,were analyzed preliminarily in the paper.

According to the severe newly increased soil and water loss caused by the mining exploitation in the Shenfu-Dongsheng coal mining area, the runoff erosion process and its characteristics on the discard soil heap slope in the Shenfu-Dongsheng coal mining area were studied by using the runoff scouring experiments.

The Effect of Coal-mining Subsidence on Water Environment in the Shenfu-Dongsheng Mining Area;
