- Abstract : because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone , its ecological environment is very fragile . based on the fragileeco - environmental , the coal mining and construction have brought out some new environmental problems . man - made debris flow problems is the most serious of them which caused by coal mining , construction of railway and highway as wellas exploiting stone . through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site , the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully . at present , this experiment method is the best way to analyze debris flow genesis and process
文摘: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 - Because the shenfu - dongsheng mine area is located in intermediate of arid and semiarid zone , its ecological environment is very fragile . based on the fragileeco - environmental , the coal mining and construction have brought out some new environmental problems . man - made debris flow problems is the most serious of them which caused by coal mining , construction of railway and highway as wellas exploiting stone . through a great deal of experiments of artificial simulation setting water rushing to two types of slope debris flow and debris flow gully in shenfu - dongsheng mine site , the characteristics is favourable to formation of debris flow ; ( 2 ) the waste gangue is easy to initiate and is main solid material of debris flow in this area ; ( 3 ) the whole debris flow process could be observed through the model simulation experiment of debris flow gully . at present , this experiment method is the best way to analyze debris flow genesis and process
