广西恭城福安页岩矿矿山地质灾害评估及其防治措施

Geological Disasters Assessment and Prevention Countermeasures of Fu'an Shale Mine in Gongcheng City of Guangxi Province

摘要:

通过了解矿山气象气候、地形地貌、地质特征、水文特征和岩土工程特征的基础上，结合矿山实际情况，从矿山现状和预测等方面进行了矿山地质灾害评估。现状评估表明，该矿山主要发育有滑坡；预测评估表明，该矿山可能引发的地质灾害主要为崩塌和滑坡，加剧的地质灾害为滑坡，可能遭受的地质灾害主要为崩塌、滑坡和地（路）不均匀沉降。根据评估结果，提出了挡护工程、排水工程和植被恢复工程等防治措施，对该矿山地质灾害作出有效的防治工作。

Abstract:

On the basis of understanding meteorological climate，topography，geological feature，hydrological characteristics and geotechnical characteristics of mines，combining with the actual situation of the mine，geological disasters assessment of mines have been carried out from the aspects of present condition and predication. It is showed that the mine has developed landslides. It is indicates that geological hazards which will probably casued are collapse and landslides，the exacerbated geological disaster is landslides，geological hazards which will probably be suffered are landslide, collaspe and differential settlement. Based on the assessment results, some countermeasures are put forward, such as block retaining works，drainage works and vegetation restoration project prevention. It will make effective prevention and controlling countermeasures for preventing geological disasters in mines.
