| 摘 要： | 神府东胜煤田我国本世纪重要能源供应地，90年代大规模开发以来泥石流频繁发生，通过实地考察发现：神府东胜煤田泥石流规模小、同人为诱发的人为泥石流，泥石流的分布特征与人工采石场等弃土弃堆放地的分布紧密对应；泥石流呈集群式分布，与地面物质组成密切相关；泥石流主要分布在面积为1km^2以下的二级沟里。 |
| 关 键 词： | 神府东胜煤田 人为泥石流 发育现状 分布特征 成因 |

| Abstract: | Shenfu Dongsheng coal field is a important base of energy supplier. Debris flows have happened there frequently since the exploitation on large scale in 1990' s. The facts have been realized through observing and studying. The debris flows in Shenf u Dongsheng coal field are small and they are induced by human factors. The distribution characteristics of the debris flows correspond closely to the distribution of sites of stone field, waste soil, residue and so on. The distribution of debris flows is group distribution and it relates to the composing of ground material. They mainly distribute in the gullies whose watershed area is under 1 km2. |
| Keywords: | Shenfu-Dongsheng coal field debris flow induced by human factors current situation of development characteristic of distribution cause |
