抚顺西露天矿防治边坡地质灾害研究

Study on slope geological hazard prevention and control in Fushun west open-pit mine

抚顺西露天矿已有100多年的开采历史,随着矿坑的不断降深,矿坑高陡边坡凸显和局部边坡失稳状况日益加剧。为了探清边坡变形破坏的机理和因素,通过对重点变形区域进行边坡稳定分析和评价,准确掌握边坡变形规律和失稳可能发生地质灾害的安全风险,建立健全监测监控和预警预报系统,实施边坡稳定综合治理工程,为露天煤矿防治高陡边坡地质灾害提供了基本方法与经验。

Fushun west open-pit mine has a mining history of more than one hundred years,with the decreasing of pit depth,the high and steep slope becomes prominent and the local slope becomes unstable.In order to figure out the slope deformation and failure mechanism and factors,through the key region for slope stability analysis and evaluation,accurately grasp the law of slope deformation and instability of the security risks of geological disasters may occur,establish and improve the monitoring and early warning forecast system,the implementation of the slope stability comprehensive treatment engineering,provides basic method and experience to open-pit coal mine geological hazard prevention and treatment of high and steep slope.
