Application of GNSS-RTK Technology in Mining Subsidence Monitoring
The traditional leveling has some problems in the mining subsidence monitoring of western coal mines,such as low efficien-cy,heavy workload,long period,and even inability to observe,especially in the complex terrain of western coal mines,which are lo-cated in loessal gully areas,mountain areas,and other complex areas.This paper attempts to apply GNSS-RTK technology to mining subsidence monitoring.Taking a working face of a mine in Shaanxi province as the research object,the GNSS-RTK technology was used to monitor the mining subsidence,and the surface deformation values and the angle parameters of rock strata movement were ob-tained.The results show that GNSS-RTK technology has certain applicability in mining subsidence monitoring and can meet the re-quirements of mining subsidence monitoring in mountainous coal mines.
