摘要
据甘肃省矿山地质地形条件和形成、运移、堆积、下切特征,将该研究区域划分为形成区、流通区和堆积区三部分。区内地形高差大,流域内山坡坡度一般在31°~60°之间,产生地质灾害的地形地貌条件和水动力条件优越,植被覆盖率低,面状冲蚀严重,具备良好的固体松散物质补给条件。本文对甘肃省矿山地质灾害形成过程、形成原因及治理措施进行了分析探讨。
According to the geological and topographic conditions of the mines in Gansu Province and the characteristics of formation, migration, accumulation and undercut, the study area is divided into three parts: formation area, circulation area and accumulation area. The terrain elevation in the area is large, and the slope of the slope in the basin is generally between 31° and 60°. The topography and hydrodynamic conditions of the geological disaster are superior, the vegetation coverage is low, the surface erosion is serious, and the solid solid is loose. Material recharge conditions. This paper analyzes and discusses the formation process, formation causes and control measures of mine geological disasters in Gansu Province.
