MONITORING STUDY ON DRIFT DEFORMATION OF DAYE IRON MINE
大冶铁矿巷道变形监测研究

In order to study drift deformation of Daye Iron Mine,4 convergence monitoring sections and 3 multi-point displacement monitoring sections are arranged. Through monitoring over one year,satisfactory data are obtained. Based on the measured data,it can be concluded that the whole drift is stable,the possibility of larger collapse is not large,and the deformation of drift floor is small. The main failure of rocks occurs on the mining side. There is obvious relationship between failure and mining,and the influence scope ranges about 100 meters. Convergence-control system can meet the needs of rock stability prediction of Daye Iron Mine during its producing period.
