摘要
针对乌山铜钼矿岩体破坏失稳诱发的地质灾害问题,基于信息量法识别滑坡风险区,并在高风险区进行多源监测,通过工程实例调查及文献检索构建了包含48个露天矿边坡滑坡案例的数据库,根据案例库搜索匹配提取预警阈值,最终构建起基于WebGIS的矿山边坡监测预警系统;研究表明,乌山铜钼矿北矿段东侧西帮、西南帮、东南帮部分区域滑坡风险等级较高,针对这些区域建立了监测预警系统,建成后运行良好,有效保障了矿山的安全生产与经济效益。
Aiming at the geological disasters caused by the failure and instability of rock mass in Wushan Copper-Molybdenum Mine,the landslide risk area was identified based on the information method,and multi-source monitoring was carried out in the high-risk area.Through the investigation of engineering examples and literature retrieval,a database containing 48open-pit mine slope landslide cases was constructed,and the early warning threshold was extracted according to the case database search and matching.Finally,a mine slope monitoring and early warning system based on WebGIS was constructed.The research shows that the landslide risk level of the west side,southwest side and southeast side in the north section of Wushan Copper-Molybdenum Mine is high.The monitoring and early warning system established for these areas runs well and effectively guarantees the safety production and economic benefits of the mine.
