GNSS/GIS集成的露天矿高边坡变形监测系统研究与应用

Deformation Monitoring System for High Slope in Open Pit Mine with the Integration of GNSS and GIS

利用GNSS/GIS集成技术设计与研发了一套快速化、高精度、智能化的露天矿边坡变形监测系统。在介绍高边坡变形监测系统硬件工作原理的基础上,引入一种直接计算法用于快速解算GNSS整周模糊度,并采用模糊评价方法对边坡稳定性进行综合评价,讨论了监测系统的软件功能和集成开发模式。以陕西省金堆城钼业集团有限公司露天矿高边坡变形监测为例开展应用研究,结果表明,该系统能够对高边坡变形进行实时快速的监测,可以为矿山安全生产提供有效的技术支撑。

It is very important of deformation monitoring system to ensure enterprises regular opera- tion and protect human lives and properties. According to the real-time and rapid monitoring demand of high slope in open pit mine, this paper aims to design a monitoring system with the integration of Global Navigation Satellite System and Geographic Information System. After its composition and op- eration principle have been introduced, the direct calculation method is proposed to perform the inte- ger ambiguity fast calculation of GNSS. Subsequently, the software function and integrated develop- ment pattern of monitoring system have been discussed in detail. Finally, the open pit mine of Jind- uicheng Molybdenum Group Company, located in Shanxi province, which is the biggest molybdenum industry production base in China, is set as an application example. The results indicate that the sys- tem can perform real-time and rapid monitoring for the high slope deformation, which provides effec- tive security for mine safety production.
