广西灌阳县某石英矿山地质灾害特征及防治措施

Characteristics and Control Measures of Geoheritage in A Quartz Mine,Guanyang,Guangxi

结合广西灌阳县某石英矿山实例,通过野外调查区域内各类地质灾害,查明现状地质灾害发育特征,评估采矿活动引发、加剧以及矿山自身可能遭受已存在地质灾害的影响,提出相应的防治措施和建议。结果表明:现状地质灾害主要为不稳定斜坡和危岩,影响程度较严重;预测采矿活动可能引发和加剧的地质灾害类型为崩塌、滑坡、泥石流、采空区地面塌陷(沉陷)和矿坑突水等,影响程度严重。针对以上可能发生的地质灾害提出了注浆加固、截水防渗、生物消能、地面变形监测、及详细的水文地质勘探等防治措施。

A quartz mine in Guanyang,Guangxi is characterized by unstable slopes and dangerous rock mass.Geohazards such as avalanche,landslide,debris flow,collapse and mine water inrush,may be triggered and exacerbated by mining activities.Some control measures such as ground deformation monitoring,detailed hydrogeological exploration,grouting reinforcement,water interception and seepage prevention,biological energy dissipation are put forward.
