Some scholars have studied the evolution mechanism of coal and rock dynamics in the process of coal seam mining [10-13], revealed the mechanism of coal and rock dynamic disasters, proposed a separate source and graded surrounding rock dynamic disaster prevention and control idea, and developed supporting technologies The equipment provides theoretical, technical and equipment support for the prevention and control of coal and rock dynamic disasters. The above-mentioned research results mainly conduct research on the deformation, failure, and instability mechanism and disaster-causing mechanism of the roof rock layer of the working face, so as to predict and warn the roof disaster. Due to related basic theories such as basic mechanics, fracture theory, geological detection technology, catastrophe theory, etc.
