摘　　要：采取野外调查和模拟径流冲刷实验方式 ,探讨了黄土高原煤炭开采区水土流失的特征和规律。黄土高原煤炭开采区水土流失形式复杂多样 ,既与原地貌条件下的水土流失有着天然的联系 ,又有采煤区独特的侵蚀形式。在模拟径流冲刷实验中 ,分析了煤矸石、自燃煤矸石。The characteristics and laws of soil and water loss in coal mining area of loess plateau were discussed by using field investigation and experimental method of simulated runoff scour.The types of soil and water loss in coal mining area on loess plateau are complex and diverse,which has the inherent relation with soil and water loss under the condition of original landforms and has its distinctive erosive form.Finally,the law of sediment yield and erosive characteristic on slopes of three types of coal heaps,i.e.,gangue,pyrophorus gangue,and gangue covered with earth.
