摘　　要：通过现场测试、工程类比及综合分析方法,取得了高水压含水层作用于原生纵向裂隙发育岩体条件下的垮落带、导水断裂带高度及发育特征的现场实测结果,并结合国内其他矿区覆岩破坏的一般规律及特点,对比分析了该类覆岩破坏的异常特征及主要原因.Expatiated the character of overlying strata with fissure under high hydraulic pressure, and introduced the conclusion observed in the coal mine of the laws and height of water conducted fissure zone and caving zone in the condition of this kind of overlying strata. Combining common laws and characters of overlying strata in other domestic diggings, analyzed the exceptional characters and primary causation of this kind of overlying strata destruction.
