【摘要】 煤层注水防治冲击地压的室内试验和现场研究结果表明:由于煤受裂隙的裂隙静永和动水压力,水的楔入、水的物理化学作用的影响,改变了煤的结构,强度、变形及冲击倾向性,从而使煤层的冲击危险程度减弱或消除。并通过煤层注水前后支承压力变化和能量释放形式变化的实例分析,进一步论述了煤层注水防治冲击地压的机理。更多还原

【Abstract】 Some experiments and study have been taken for investigating prevention mechanism of rockburst by coal seam water infusion,Coal seam water infusion can weaken or delete dangerous extend of rockburst in coal seam by static and dynamic crack water pressure,injection,physical and chemical actions,which change coal seam structure,strength,deformation and inclination of rockburst.A applied example is given to explain the process of energy release and change of abutment pressure beore and after water infusion,furtherly to discuss the mechanism of rockburst prevention by coal seam water infusion.更多还原
