Introduction

Rockburst is a dynamic phenomenon in the mining process of coal mines, which is influenced by coal and rock properties, geological structures, mining layout, coal pillar retention, etc. Under the action of original rock stress and mining stress, the elastic energy accumulated in the coal and rock mass around the roadway or working face is instantaneously released, causing severe damage. Its prevention and control is an urgent problem to be solved in the field of coal mine safety production, attracting the attention of many experts and scholars, especially scholars engaged in the above-mentioned related field engineering practice. There is still no clear theoretical guidance and reliable control technology for the mining of extra-thick coal seams, and serious rockburst accidents still occur from time to time.
