Research and application of mine safety monitoring based on rock shift observation technology
In order to reduce the risk of goaf collapse in the mining process of mineral resources,a mine safety monitoring research and application method based on rock shift observation technology is proposed.This method uses RTK technology to collect the carrier phase safety monitoring data of monitoring points in mine subsidence area.Based on the monitoring data,the carrier phase data is converted into spatial cartesian coordinate system and geodetic coordinate system,and then the transformed carrier phase data is input into the mine rock movement monitoring model,and the model is used to obtain the Euler movement Angle and movement vector of monitoring points in mine subsidence area.Then,the rock displacement value of monitoring point in mine subsidence area can be obtained,and the comparison between the value and the datum point can realize the mine safety monitoring.The experimental results show that this method has a good ability to acquire the carrier phase of monitoring points in mine subsidence area,and can effectively obtain the average value of rock displacement of monitoring points in mine subsidence area,and the results are more accurate.
