In order to prevent and control the rockburst of the hard and thick coal seam in 22 panels, the laboratory tested the impact propensity of coal seams and roof rock layers. It used the comprehensive index method and microseismic monitoring to evaluate the risk of medium rock burst 3# coal seam in 22 panels. Anti-scouring countermeasures are proposed, including regional anti-scouring, local anti-scouring, danger zone relief, anti-scouring effect inspection and safety protection, etc., which provide reference for mines with similar conditions.
