陕西榆神府生态脆弱矿区地质灾害演化过程
Evolutionary Process of Geological Hazards in Yushenfu Ecological Fragile Mining Area
摘要
Abstract
Because of the effect of natural and human factors interweave,iterative.Ecological environment become fragile sensitive and variable,water resources shortage,land desertification and soil erosion is serious in Yushenfu mining area of Shaanxi.Gestate,occurrence,development and the formation of the geological hazards ex-acerbated the fragility of eco-environment.In this paper,based on expounding development characteristics and dis-tribution regularity of geological hazards,discuss the evolutionary process of collapse,landslide and ground collapse in yushenfu area.The evolutionary process of landslide,collapse is loess ravine→fragile natural slope→human ac-tivity→formation of unstable slope→coupled with water,soil,rock and human function→geological hazards occur-rence→exacerbated the fragility of eco-environment.The evolutionary process of ground collapse is lake and river deltaic deposits→gathered coal-bearing strata→balance of soil or rock mass stress in a natural state→human exploit and utilize of mineral resources→the formation of mining empty area→surrounding rock stress redistribution→ground deformation→ground collapse occurrence→exacerbated the fragility of eco-environment.关键词
