摘要
Abstract
This paper discusses the efforts to address the insufficient elevation measurement accuracy in the high-scale topographic mapping of mining areas and daily monitoring of ground subsidence areas by using CORS-RTK surveying.Based on the primary(Class C)GNSS control network static observations of geodetic height in Hegang mining area and the third-order leveling data in the co-surveying 85 elevation system,the study refines the quasi-geoid model of the mining area using the"remove-restore"method for EGM2008 model.The results show that the refined model provides elevation anomaly values in Hegang mining area with the improvement of the elevation accuracy of CORS-RTK surveyed ground pointsfrom over 20 cm to within 2 cm.The proposed study offers a simple and efficient solution to the issues mentioned and expands the application scenarios of RTK in the surface subsidence monitoring in mining areas.关键词
