摘要
河北省滦平县华兵铁矿选厂区地处燕山山脉东段,构造以褶皱为主,新生代构造活动微弱,区域地质构造条件属简单型,拟建场地稳定性较好,适宜该项目修建,但人类活动强烈,对地质环境的影响、破坏严重。通过对拟建项目地质条件现状调查,评估认为:该拟建项目区内滑坡、崩塌、泥石流、地裂缝等地质灾害危险性小,而采空区塌陷地质灾害危险性大;在该项目建设中和建设后,滑坡、崩塌、泥石流地质灾害危险性小,地裂缝地质灾害危险性中等,采空区塌陷地质灾害危险性大。综合评估拟建项目区地质灾害危险性大,并提出了相应的防治措施。
Located in the eastern section of the Yanshan Mountains, the dressing plant of Huabing Iron Mine in Luanping County, Hebei Province, is dominated by folds and has weak Cenozoic tectonicprocess. The regional geological structure conditions are simple. The proposed site has good stability and is suitable for the construction of the project. But the strong human activities have seriously affected and damaged the geological environment. Through the investigation of the current geological conditions of the proposed project, it is concluded that the risk of geological disasters such as landslide, collapse, debris flow is small, the risk of ground crack is medium, while the risk of goaf collapse is large. Comprehensive assessment of the proposed project area verified high geological disaster risk, and the corresponding prevention and control measures were put forward.
