With the increase of coal mining depth, the risk of strong mineral pressure and composite dynamic disaster faced by deep coal seam mining is significantly aggravated. Aiming at the prevention and control of strong mineral pressure disaster induced by superposition of multiple working faces in deep coal mines, the engineering background of Zhaozhuang Mine is the three times square area of 1311 working face (strike 698-938m), and the dynamic evolution law of the quarry perimeter rock structure and the disaster mechanism of strong mineral pressure are revealed through the integration of microseismic monitoring, stress on-line monitoring, bracket resistance analysis, and fissure development observation and other multi-source monitoring means. The study shows that: ① microseismic events in the vertical - tendency of the “arch” type distribution, the scope of activity is concentrated in the coal seam above 60m, the most intense activities in the middle of the working face roof; ② the influence of the over-supporting stress range of up to 150m, the value of the stress is growing with the advancement of the working face, the section of the coal pillar with the work face near the first increase in the stress is shown, Subsequently, the stress in the coal pillar is maintained at a high level, and after the monitoring point enters the hollow area, the concentration of coal pillar stress is slowly reduced; ③The working face shows the characteristic of “upper big and lower small” pressure, the average step distance of the upper measurement area is 10.96m (the dynamic load coefficient is 1.28), and the step distance of the lower measurement area is shortened to 10.08m, and the dynamic load coefficient is increased to 1.34, which reveals that the lower part of the working face has a very intense stress. 1.34, revealing that the risk of strong mineral pressure in the lower area is significant; ④ After the implementation of directional hydraulic fracturing of the roof plate and energy blasting, the fissures on the roof plate of the roadway are concentrated in the 11-27m level, which reduces the integrity index of the roof plate, thus effectively blocking the path of stress transmission; ⑤ The monitoring of the deeper delamination reveals that the amount of peripheral rock delamination is significantly larger than that of the shallower part of the 9m range, which verifies the collapse of low rock layers as the main reason of the disaster caused by the dynamic loading. The study proposes the theory of “static-dynamic dual source”: the static load environment formed by the over-supporting stress and the dynamic load disturbance triggered by the development of fissures in the low rock layer, the expansion of the off-layer, and the collapse of the low rock layer form the composite conditions for the disaster. The research results provide theoretical and technical support for the prevention and control of deep composite dynamic disasters.
