Abstract: Taking Yunhe Coal Mine 6303 working face as the research background, the practical investigation and theoretical analysis show that the working face has great rock burst risk under the influence of complex tectonic zone. We studied the mechanism of rock burst under this type according to the actual situation of 6303 working face. And through the RFPA software, we simulate the rock burst risk of two mining methods and determine a reasonable mining method. Finally, the engineering practice takes reasonable unloading measures to ensure the safe recovery of the work surface.
