Abstract: In view of the problems of complex structure of deep body, high ground stress and frequent of impact ground pressure during coal production and mining in Yuncheng Coal Mine, combined with field investigation, 3DEC is used to establish the numerical model of two-dimensional discrete element. At the same time, a similar simulation was carried out to analyze the disaster mechanism of rock burst in the fourth fork of return wind roadway of Yuncheng Coal Mine, combined with the dynamic instability model of the roadway, the disaster-causing mechanism and prevention method induced by deep coal seam rock burst are explored. The results show that: the high stress accumulated in deep coal seam is the main cause of the impact pressure. This paper proposes the prevention and treatment method of pressure relief by taking stress control as the center, adopting different borehole layout methods and rationally arranging blasting points. It can effectively release the accumulated high stress in the clearance area, weaken the continuous stress transfer capacity and dissipate the accumulated high energy, which can also release the stress of the roadway coal body. Through field practice and application, the pressure relief effect is obvious.
