Application research of dual source collaborative shaft deformation monitoring system

The damage of coal mine shafts will cause serious production risks and economic losses.After analysis of the characteristics of shaft deformation monitoring methods, combined with the shaft engineering practice of Mataihao Coal Mine, this paper based on the principles of reliability, advancement, economy and monitoring of the key areas, steel-wire datum combined with sensor technology is proposed to monitor shaft deformation.First of all, the method of steel-wire datum deformation monitoring get the shaft deformation data, and the conditional adjustment method with parameters is used to analyze and process the data, fit the center and radius of the circle about 34 shaft sections, established a 3D model with MATLAB, and judging the current state of the shaft.Then the sensor monitoring method, through the sensor of the automatic monitoring system to achieve real-time data collection and display of the shaft deformation data to achieve the purpose of continuous monitoring.The application research of the wellbore deformation monitoring system has verified the feasibility and reliability of the dual source collaborative monitoring method in the wellbore deformation monitoring work, which provides an empirical basis for the subsequent similar wellbore monitoring projects.
