Some scholars have studied the evolution mechanism of coal and rock dynamics in the process of coal mining [10-13], revealed the mechanism of coal and rock dynamic disaster occurrence, proposed the prevention and control idea of surrounding rock dynamic disaster based on source separation and classification, and developed supporting technical equipment, which provided theoretical, technical and equipment support for coal and rock dynamic disaster prevention and control. The above research results mainly through the study of deformation, failure, instability mechanism and disaster mechanism of roof strata, so as to predict and early warning the roof disaster. Due to the limitation of basic mechanics, fracture theory, geological exploration technology, catastrophe theory and other related basic theories and technology development, it is difficult to obtain the accurate theoretical analytical solution of roof fracture instability and disaster occurrence mechanism.<br>
