摘要 文中通过康平煤田三个独立综放开采工作面覆岩破坏的观测,获取了导水裂缝带最大高度和离层带的高度范围,研究成果对即将进行的库下工作面安全开采具有重要的指导意义。 Based on observation of the overburden destruction on three independent fully-mechanized coal mining faces with caving of roof coal in Kangping coalfield,the maximum height of the water flowing fractured zone and the height range of the separate zone are obtained in the paper,which have important instructive significance for safe mining of coal faces to be operated beneath a reservoir
