摘要
利用GIS空间分析方法,对格木底的玉舍煤矿的地质灾害现状进行分析和评价。在分析时,选取地形坡度、地层岩性、断层情况和地质灾害现状为基础因子,道路级别、受威胁人口密度和土地资源类型为易损因子,选取此7个影响因子对研究区的地质灾害现状进行评估。得出评估区重度危险区面积总和为1.54km2,占总评估面积的2.97﹪;中度危险区面积总和为4.21km2,占总评估面积的8.1﹪;轻度危险区面积总和为46.241km2,占总评估面积的88.94﹪。为矿山地质环境的恢复提供了一定的理论指导。
This paper analyzes and studies the mine geological disasters of Yese mine in Gemudi by using GIS technology. In the analysis, the terrain slope, formation lithology, faults and geological hazards are selected as the basic factors, and the road level, density of threaten population and type of land resources as vulnerability factors. This seven impact factor are selected to assess the geological disasters of the study area. Then it is obtained that the area of severe danger zone is 1.54 kilometers, and occupies 2.97% of the total assessment area. The moderate area of severe danger zone is 4.21 kilometers, and occupies 8.10% of the total assessment area. The mild area of severe danger zone is 46.24 kilometers, and occupies 88.94% of the total assessment area. Provide some theoretical guidance for the reply of mine geological environment.
