1 Introduction Coal burst represents a dynamic occurrence in coal mine underground mining, influenced by factors including coal and rock characteristics, geological formations, mining configurations, and coal pillar arrangements. When subjected to both natural and mining-induced stresses, the accumulated elastic energy in the surrounding coal and rock masses near tunnels or excavation faces is rapidly discharged, leading to extensive damage.

1 Introduction With the increase of mining depth and mining intensity, the coal burst disaster faced by deep mines is becoming more and more serious. One of the main causes of coal burst is the high stress on coal [1-4]. The existing means of coal burst prevention are mainly divided into regional prevention technologies and local pressure relief technologies [5]. Local pressure relief methods mainly include coal seam water injection, large-diameter drilling pressure relief, and so on [6].
