摘要
神府东胜煤田是我国重要的能源重化工基地 ,自 1987年大规模开发以来泥石流频繁发生 ,通过野外考察发现 ,神府东胜煤田泥石流属由人为诱发的人为泥石流。详细地分析了该区泥石流形成的三个基本条件 :丰富的松散固体物质储备、陡峻的地形条件和沟床比降和高强度长历时的降雨过程 ,认为在流域内人为堆置的大量松散弃土弃渣物质是该区泥石流形成发育的主要因素。
Shenfu-Dongsheng coal field is an important base of energy resources and heavy chemical industry of our country ,since the large scale development in 1987, mud rock flows occurred frequently. According to the investigation, mud rock flow in Shenfu-Dongsheng is caused by human activities. Three basic conditions that triggered mud rock in the area are analyzed , ie rich loose solid material reserve, precipitous topography condition and ditch bed than fall with high strength length and duration rainfall process,it is think that artificial pile of plenty of abandoned earth and dregs is the major factor causing mud rock flow in this area.
