Research on the Simulative Experiment System and Application to the Damaged Regularity in Composite Rock-mass Roadway

The research concentrates mainly on the structure and function of simulative experiment sys-tem and its appliction. The crack development of failure process in composite rock-mass material and statis-tical regularity including the stress,displacement,time and space each other through mining simulative experi-ment can be inferred from the process inspection in-formation. It is a vitally fundamental research to analyze the strata control due to the muti-coal seams mining under the complicated rock mountain and building.
