甘肃省天祝县矿山地质灾害类型及基本特征

Types and basic characteristics of mine geological hazards in Tianzhu County,Gansu Province

甘肃是矿产资源大省,矿产资源开发利用规模大,强度高,因而存在非常突出的矿山地质环境问题。尤其是天祝县矿山地质灾害具有类型多、危害严重的特点,对当地矿山事业持续稳步发展形成较大阻碍。为此,下文结合实践,对甘肃省天祝县矿山地质灾害主要类型和基本特征进行分析探讨,指出这些矿山地质灾害的危害特点。通过研究发现当地的矿山地质灾害主要包括泥石流、滑坡、崩塌、不稳定斜坡等几种类型,矿山地质灾害的分布和发育特征与天祝县的地质环境条件,矿山开采规模及其方式密切相关,危害特点和矿山灾害的发育特征与活动有着非常紧密的关联性。

Gansu is a province with large mineral resources.The development and utilization of mineral resources has large scale and high intensity,so there are very prominent mine geological environment problems.In particular,Tianzhu County's mine geological disasters have the characteristics of many types and serious hazards,which greatly hinders the sustainable and steady development of the local mining industry.Therefore,combined with practice,the following analyzes and discusses the main types and basic characteristics of mine geological disasters in Tianzhu County,Gansu Province,and points out the hazard characteristics of these mine geological disasters.Through the research,it is found that the local mine geological disasters mainly include debris flow,landslide,collapse,unstable slope and other types.The distribution and development characteristics of mine geological disasters are closely related to the geological environmental conditions,mining scale and mode of Tianzhu County.The hazard characteristics and the development characteristics of mine disasters are closely related to activities.
