Abstract: In order to study the control effect of fault structure on rock burst in Junde mine field, southern mining area of Hegang coalfield, the control effect of fault structure on rock burst was studied., based on geodynamic zoning method, analytic hierarchy process and vulnerability index method.Taking the 17 coal seam of Junde Coal Mine as the research object, the fractal calculation and fea-ture analysis of I ~ V fault blocks are carried out by using fractal theory.In view of the seriousness of rock burst in 17 coal seam of Junde Coal Mine, the tectonic stress zoning of 17 coal seam is divided, and the correlation between fractal dimension of fault structure, tectonic stress state and rock burst is analyzed.The results show that from the perspective of overall fractal dimension, the V-level fault block in Junde mine field has statistical self-similarity and spatial geometric fractal characteristics.The overall fractal dimension of the fault is 1.2714, of which the fractal dimension of the NE-trending fault is 1.0964, and the fractal dimen-sion of the NW-trending fault is 1.1236. It shows that the NW-trending fault plays a controlling role in the rock burst of Junde Coal Mine, while the NE-trending fault has an important influence on the rock burst. The analytic hierarchy process is used to de-termine the weight of each influencing factor, and the GIS software is used to normalize and superimpose it. The study area is di-vided into four regions. In the past, rock burst accidents mostly occurred in dangerous areas, which is consistent with the actual situation.The research method provides a scientific basis for the prevention and control of rock burst disaster.
