【摘要】 阐述了高水头压力原生纵向裂隙发育覆岩的特征,介绍了该类覆岩条件下垮落带、导水裂缝带高度及发育特征的现场实测结果,结合国内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。
【Abstract】 The paper expatiated on the overlaying strata failure characteristic of high hydraulic pressure and primordial lengthways crannies,and introduced the road-test result and characteristic about caving zone and water conducting fractured zone.Combining with the ecumenical disciplinarian in China,the paper construed the exceptional overlaying strata failure characteristic and primary causation.
