| Abstract: | At present, surface movement observation station is still an effective technical means for research of surface movement and deformation law of a mine under the influence of mining subsidence. Development and application of new mapping technology provide various advanced methods for surface movement observation station. This paper introduced electromagnetic wave height measurement method instead of geometrical leveling for acquiring elevation information of each monitoring site. Through observation test and precision analysis, this method is workable in technique and tolerable in precision, greatly simplifying measurement procedure and improving work efficiency. |
