- Abstract:
- 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.The results indicated that,under the same rainfall intensity,the initial infiltration rates of all the underlying surfaces were similar,and the steady infiltration rate of disturbed soil slope was the biggest one among the different underlying surface slopes,and that of earth road slope was smaller than that of undisturbed soil slope.In addition,all the infiltration rates of the different slopes increased firstly and then reduced with the increasing of rainfall duration.The peak of sediment yields for three different underlying surfaces appeared in the initial 0~20 min of simulated rainfall,after then all the sediment yields reduced and then kept relatively steady.During the simulated rainfall experiments,the sediment concentration of earth road kept small and steady,while those of other underlying surfaces were high at the beginning stage of rainfall,then reduced remarkably,and were finally close to that of earth road slope.
