神府东胜矿区位于黄土高原北部干旱半干旱过度地带。由于煤田的大量开采，诱发了大量的环境问题，尤以人为泥石流最为严重。本文以神府－东胜矿区人为泥石流为研究对象，采用人工放水冲刷模拟实验的方法，分析了坡面型和沟谷型泥石流源地松散体起动、产沙、泥石流过程的特性，所得结论为：（１）放水历时长、强度大，有利于泥石流的形成；（２）弃土石渣易起动，是该区泥石流固体物质的主体；（３）沟道型泥石流放水冲刷模拟实验．便于观测泥石流的全过程．坡面型泥石流放水冲刷模拟实验，利于统计产沙、观测侵蚀形态。 Shenfu Dongsheng mine is located in northern arid and semi-arid overhangs of the Loess Plateau. Due to the large-scale exploitation of coalfields, a large number of environmental problems have been induced, especially man-made debris flow is the most serious. In this paper, artificial debris flow in Shenfu-Dongsheng mining area is taken as the research object. By using artificial flushing simulation experiment, the characteristics of loose debris start-up, sand production and debris flow in slope type and valley debris flow are analyzed. The conclusions are: (1) Lifting water lasted a long time, the strength is large, which is propitious to the formation of debris flow; (2) The spoil of the spoil is easy to start, which is the main body of the debris flow solid material; Easy to observe the whole process of debris flow. Slope debris flow discharge scour simulation experiments, which will help statistical sediment production, observation of erosion patterns.
