为使沿空的回采巷迫处于稳定状态,必须根据不同的围岩结构选取和采用相应的矿压管理措施。针对不同的顶板类别选取积极的矿压管理方法是最合理的。全苏煤炭科研所、全苏矿山测量科研所、斯柯琴斯克科研所、伯绍尔设计研究院和顿涅茨煤炭科研所等单位制订的组顶板分类方案,都没有考虑沿空巷道矿压显现的特点,因此这些分类方案基本上只适用于回采工作面的顶板管理。
In order to keep the empty mining lane in a steady state, corresponding rock pressure management measures must be selected and adopted according to different surrounding rock structures. It is most reasonable to choose an active method of rock pressure management for different roof types. All coal research institute, the Soviet Union Institute of Surveying and Mapping Surveying and Mapping, Schokchensk Institute of Science, Berdauer Institute for Design and Research and Donets Coal Research Institute and other units to develop the group roof plan, have not considered underground roadway pressure Therefore, these classification schemes basically only apply to the roof management of mining face.
