| 摘 要： | 在神府东胜矿区，以矿山泥石流成灾的人为特殊性为基础，经济区位影响为目的，选择泥石流形成和成灾的自然、经济区位、人为三个方面的9个因子，43条矿山泥石流样沟，应用运筹学原理，将层次分析与模糊信息推断相结合，进行了成灾程度分析。结果显示：50％以上的泥石流沟属于强成灾范围。

| Abstract: | The comprehensive evaluation of mine debris flow disastrous danger degree is aimed at human being community and economical activity center.In the region of population rare,the same kind and intensity degree of debris flow,the disastrous danger degree differs from in the region of population crowded and economical center.Based on the idea,we abide by three basic theory of region division law and economical geogrophical and economy ,and work out five basic principle.According to mine debris flow forming reasons and effect degree on mine region development,combining reality situation of Shenfu-Dongsheng mine region,we select out dominant factors of 9and mine debris flow sample gullies of 43,and go on fuzzy comprehensive evaluating in operational research principle.The results show that dominant factors of 9 is order of loose solid accumulating materials reserve capacity>distance away from mine region center>gully drainage information dimension>minerals resource exploiting ways and scale>distance away from traffic route net>precipitation>compratively distance between mine debris flows>drainage area>materials composing proportion.And danger degree is divided into 5 grades that they are most disastrous danger district,disastrous danger district ,middle danger district,light danger district,nearly without danger district.There are not nearly without danger district in mine debris flow sampling of 43 because they all are more activity mine debris flow gullies. |
