- W2359512070 abstract "Using hollow inclusion method measure the in-situ stress of Kailuan mining area.In-situ stress field types,interaction behavior and the relationship between regional structure was systematically analyzed.Based on this,the inner relationship between in-situ stress field and coal and gas outburst,rockburst,water inrush and other coal and rock dynamic disaster was analyzed.Studies show that in-situ stress field in Kailuan mining area belongs to the Earth dynamical field,the horizontal tectonic stress is dominant,and it belongs to the high stress zone.In-situ stress magnitude and orientation is controlled by Kaiping syncline.Stress value is the highest in Kaiping synclinal axis section.As far away from the axis,the stress value decreases gradually.The maximum principal stress orientation and axis trend of Kaiping synclinal is approximate vertical.At the same time tectonic stress field controls coal structure,coal gas parameters,permeability and so on.In the Kailuan mining area,coal and gas outburst and rock burst occurred in synclinal axis section of Kaiping where stress value is highest,water inrush occurred in the Kaiping syncline wing where stress value is the lowest.Coal and rock dynamic disaster in Kailuan mining area is in the unified tectonic stress environment." @default.
