摘要
为了加强露天矿山的边坡安全管理工作,提高对崩塌、滑坡等地质灾害的应急管控能力,基于全球导航卫星系统研发的GNSS边坡监测技术对白音华二号露天煤矿的边坡进行稳定性监测;采用单点测量、多点连线、区域组网等布置设计构建了采场、排土场边坡的在线监测网络,通过监测数据对比及曲线跟踪分析,实时掌握边坡岩体的动态变形情况。结果表明:GNSS边坡监测技术可以有效监测边坡岩体的变形趋势,为白音华二号露天煤矿的边坡安全管理提供有力的技术支撑。
In order to strengthen the slope safety management of open-pit mines and improve the emergency management and control ability of geological disasters such as collapse and landslide,the slope stability of Baiyinhua No.2 open-pit coal mine was monitored based on GNSS slope monitoring technology developed by global navigation satellite system;The on-line monitoring network of stope and waste dump slopes is constructed by using the layout design of single point measurement,multi-point connection and regional networking.Through the comparison of monitoring data and curve tracking analysis,the dynamic deformation of slope rock mass is mastered in real time.The results show that GNSS slope monitoring technology can effectively monitor the deformation trend of slope rock mass,and provide strong technical support for the slope safety management of Baiyinhua No.2 open pit coal mine.
