Abstract: In order to study the mechanism of rock burst during the gob-side roadway driving of small coal pillars under the condition of thick and hard roof in hujirt mining area, the stress distribution model and flac3d numerical model during the roadway breakthrough gob-side roadway were established based on the mine pressure behavior during the penetration of 11-3107 gob-side roadway in Menkeqing Coal Mine. The stress evolution characteristics of heading face at different distances from the roadway breakthrough point were compared, and the mechanism of rock burst during the roadway breakthrough of gob-side roadway was revealed. The deformation of roadway surrounding rock and coal body stress were measured by means of cross distribution method, stress, micro seismic and other monitoring methods. Based on mechanism analysis and field measurement, the integrated technology of pressure relief and support is proposed. The results show that due to the existence of thick and hard rock strata above the roof of the coal seam, after the excavation of the roadway, the thick and hard rock strata act on the surrounding rock of the roadway through stress transfer, resulting in large deformation of the roof, floor and side of the roadway lagging behind the drilling head. With the closer distance between the drilling head of the roadway and the roadway breakthrough point, the deformation of the roadway gradually increases. Through the increase rate of the deformation of the roadway, it is clear that when the distance from the penetration point is about 160 m, the deformation of the roadway begins to increase sharply. The microseismic events are mainly concentrated in the roadway roadway breakthrough area within 190 ~ 60 m from the roadway breakthrough point, and the theoretical calculation is consistent with the field mine pressure appearance.
