Abstract: In the early middle Jurassic, Jurassic basin in west Beijing entered the important coal-forming period. It shaped current tectonic patterns during middle and late Yanshan tectonic movement. The study of controlling action on coal seam occurrence by regional tectonic and its evolution has great importance for revealing the dynamic background of mine dynamic disasters in west Beijing. The paper, based on the regional tectonic background for mine dynamic disasters in west Beijing coalfield, combined with tectonic stress field distribution characteristics, using geological dynamic division hollow contrast strength evaluation methodology, gave quantitative evaluation indexes to the mines which have hydraulic disaster condition. By the analysis, it was identified that there exist dynamic environments for dynamic disasters in coal mines in west Beijing coalfield, which has realistic significance for guiding safe mining.
