Jan 01, 2012· Based on a RUSLE model, we identified the key factors of the impact on soil erosion induced by coal mining subsidence. We designed a method for predicting LS factors of a mining subsidence basin, using analytical GIS spatial technology. Using the Huainan mining area as an example, we calculated the modulus of erosion, its volume and classified the grade of soil erosion
