摘要
讨论了不同顶板结构特征及其变形破坏形式,分析了采面矿压显现特征及其与顶板岩石组成的关系,为煤矿设计。
Discussed the different roof structure characteristic and its deformation failure patterns.Analyzed the relation between the strata behaviour characteristic of coal working face and the rock mass composition of the roof.Provided the necessary data for reasonable choice support method.
