The Altimetry of Electromagnetic Wave on the Observation Station of the Earth''''s Surface Subsidence of Diggings

Along with the promotion and application of the measurement system of entire station meter, instead of the quarter - geometry leveling method, the altimetry by using electromagnetic wave has already been used to gain the monitor information about the surfaces migration and distortion. And its also applied to the research on the rules of the surface S migration and distortion in diggings. This paper introduces the idiographic methods of operation concerning how to usethe altimetry of electromagnetic wave to replace the quarter - geometry leveling. Also analyses the measuring accuracy through deducing some theories. The application of this method makes the observation of plane and elevation progressed synchronously. WhatS more, it fully displays the superiority of three - dimensional synchronized observation by using the entire station meter. Through the practice, it has proved that, advantages of this method are simple operation,high automatic degree, reliable precision. And it is worth popularizing.
