Study on Law of Movement and Deformation of Overlying Strata in Deep Mining
3-D semi-analytical numerical calculation program of finite layer and finite prism coupling was applied by analyzing structural types and features of overlying strata mass, obtaining the status of movement and deformation of overlying strata in deep mining, and discussed the time-space interaction between structural deformation and mining, and movement law of abscission layer crack along structure level of overlying strata using physical similar simulation, and detected the evolution of structural deformation of rock mass before and after mining by means of drilling hydrogeology exploring, drilling ultrasonic imaging and geophysical method in field, gaining the reliable, visual and clear results.
