Abstract: The phenomenon of surface subsidence caused by mining is very common in mining area. So strengthening the mining surface subsidence problem detection and research has become an important issue for mining sustainable development. The traditional monitoring method is to set up the surface movement observation station, and obtain the data of the mine surface movement by the level measurement. But this method needs heavy field work and it is difficult to acquire real-time data dynamically. And it fails to obtain the dynamic laws of surface subsidence. In this article, vertical survey precision of TCA2003 measurement robot is analyzed to guarantee its feasibility in monitoring mine subsidence. Then an engineering case demonstrates that dynamic subsidence monitoring based on measurement robot is effective. Finally, the characteristics of surface subsidence and subsidence velocity on different time scales are analyzed based on a mass of surface dynamic subsidence data.
