GNSS边坡监测与事故风险分析平台融合应用

Integrated Application of GNSS Slope Monitoring and Accident Risk Analysis Platform

在露天煤矿开采过程中,边坡的稳定性关乎矿山正常的生产运营。在矿山建设投产开始直至采完闭矿,滑坡、裂缝等影响始终贯穿矿山的整个开采周期。传统的人工光学设备边坡稳定性监测方式,无法满足全天候、全时段监测,从而延误了预警的最佳时机。随着卫星导航技术和差分解算技术的发展,GNSS边坡监测方式以其低成本、全天候实时监测的优点逐步成为矿山监测的主要方式。本文以山煤进出口集团河曲旧县露天矿为例,通过两期GNSS边坡、排土场监测案例,介绍了全球卫星导航系统原理、边坡监测系统组织架构、多源数据融合等。

In the process of open-pit coal mining,the stability of slope is related to the normal production and operation of the mine.From the beginning of mine construction and production to the closing of mining,the influence of landslide and crack will run through the whole mining cycle.The traditional slope stability monitoring method of artificial optical equipment cannot meet the requirements of all-weather and whole-time monitoring,thus delaying the best opportunity for early warning.With the development of satellite navigation technology and differential decomposition technology,GNSS slope monitoring has gradually become the main way of mine monitoring with its advantages of low cost and all-weather real-time monitoring.Taking GNSS slope monitoring in Hequjiu County open-pit mine for example,this paper analyzes the principle,system composition and practical application of GNSS slope monitoring.
