Abstract


Our country contains very rich mine resources, and has now completed about tens of thousands of mines. At the mine slope implement accurate, real-time security monitoring is very important. This paper introduces the mine slope monitoring purposes, tasks, requirements and methods, summed up the conventional monitoring methods GPS existing problems: high costs, poor observation, grade cloth network, real-time and synchronization of the poor.Through Slope Mine in Jiangxi a baseline monitoring network engineering example, launched a high-precision measurement than GPS measurement experimental study demonstrated GPS technology used in mine slope deformation monitoring of technical feasibility study of the need to take measures and methods. Through the relevant theoretical research of GPS deformation monitoring network design, design suitable for measuring the deformation monitoring network and then proceed to the data acquisition, data acquisition and measurement of the use of optimization methods for data analysis. Comparison of parameters of the method, by analyzing GPS baseline accuracy, precision and point coordinates of the situation, determine the deformation monitoring GPS used for the best parameters: the high degree of closing angle, the length of time, the best observation period, the number of benchmarks and distribution, the start point coordinates precision, tropospheric parameter estimation. In addition, this paper conventional Corner network and GPS measurement process than through conventional Corner and the network side, coordinates the comparison and analysis to prove that high-precision GPS deformation monitoring practice for the feasibility and mastered the GPS technology used in mine slope deformation monitoring method, which is conducive to direct production guidance to achieve the expected goal of the experimental study.
