Research on Prediction Parameters in Overlying Rock of Coal Mine

For establishing the relationship between probability-integral parameters in rock body and surface parameters, the study conducted a comprehensive observation on overlying strata movement caused by the tilt coal seam mining based on the similar material model. According to the subsidence and horizontal movement value, the study gets the estimated parameters in different layers, and analyzes the variation law, and obtains the rock prediction parameters relation deduced by the surface parameters.
