Research, Development and Application of Surface Displacement Automatic Monitoring System of Tailings dam

An effective monitoring system is conducive to grasp the dynamic evolution process of disaster occurring, to study the disaster-mechanism, to forecast the future development trend and ultimately to predict the disaster occurring. In this paper, focused on the surface displacement, an automatic on-line monitoring system of tailings dam which based on GSNI/GPRS communication platform has been researched and developed. As a part of tailing pond disaster monitoring system, the researched and developed monitoring system could monitor the surface displacement of tailings dam automatically and remotely, and also can collect deformation data regularly and transfer to distant control center real-time. According to its application in an iron tailings dam in Diaxian, Shanxi Province of China, the researched and developed monitoring system could achieve the same monitoring effect with the electronic total station. This automatic monitoring system provided another method to grasp the dynamic evolution process of tailings dam from stability to failing down.
