摘要
The invention belongs to the technical field of mining and safety engineering and discloses a rock burst control method in a deep mining area of a coal mine. The method comprises the following steps: a, arranging a first coal mining face on an upper coal seam in a mining area uphill direction; b, arranging a mining area uphill preparation roadway group in a stress decreasing area below the gob; c, arranging an upper coal seam working face and a lower coal seam working face on two sides of the main system for performing stoping after the uphill preparation roadway group is formed; d, performing local pre-unloading treatment or rock burst danger releasing measures on a haulage way, a tail gate, an open-off cut and the like of the upper coal seam working face. The invention provides a method for effectively improving the rock burst control effect in the deep mining area of the coal mine.
