With the state of the coal industry structure adjustment, which requires in the old mining area, maintenance to in the construction of mining area to strengthen the monitoring, and continuously improve the efficiency and output of coal mine, with coal as the main energy in China, in the development of the national economy plays an important role. So it is very important to carry out real-time and effective monitoring of well bore, but also to study the inherent law of the mine.In this paper, we analyze the shaft force and the wall of concrete failure criterion, thus further study shaft deformation and the monitoring. Combined with the engineering project in Tongting Coal Mine, the deformation monitoring points across the entire wall symmetrically arranged 2 levels with a total of 8 concrete (each level are symmetrically arranged 4 points), with vertical displacement variation in monitoring borehole aquifer in section fourth, in order to obtain "four vertical borehole data changes with time" the amount of compression of the ground; Tongting mining industry and artificial observation in the wide scope of ground settlement with the change trend, combined with the borehole vertical compression monitoring of the generator and the ground settlement and provide the basic data for the wall from the theory that Tongting Mine Deformation Observation; mining area of the aquifer (mainly four with the change of water level) characteristics, obtain aquifer water level changes and the corresponding wall vertical stress changes and ground settlement between the associated data, provide monitoring for forecasting the number of shaft safety According to the. To study the Tongting Coal Mine auxiliary shaft of the ground deformation above data.
