At the end of mining, the stress in the concentrated roadway group is highly concentrated, which has a high impact risk. In view of the difficult problem of rock burst prevention and control at the end of mining in the working face, taking the 4105 working face of wenjiapo coal mine as an example, the impact risk of the final mining area is analyzed through the micro earthquake, ground sound and stress monitoring system, and the impact disaster causing factors are further analyzed. The technical scheme of separate source prevention and control of the dynamic and static load source inducing the impact start is put forward, the blasting pre splitting is adopted for the roof, and the large-diameter drilling is adopted for pressure relief in the coal seam, The engineering practice and effect test are carried out. The field application shows that the microseismic activity is in the state of "high frequency and low energy", the daily released energy decreases by 82.5%, the proportion of geoacoustic C and D early warning shifts decreases by 32%, the stress concentration degree of coal body is relieved, the application effect is good, and the impact risk in the final mining area is effectively reduced.
