摘要
分析了各种巷道维护的顶部应力控制法。借助连续介质力学理论，详细分析了顶板开槽下方围岩的应力分布状态及其影响因素，进而确定了顶部应力控制法的适用范围和合理参数，通过井下实践表明：顶部开槽适用于顶压大、侧压较小的情况；开槽底板与巷道顶板之间的距离应与巷道宽度相当。
Methods for stress control in the roof are analyzed for roadway maintenance. Based on continuous medium mechanics, the stress distribution in the surrounding rock under the roof slot and its influencing factors are discussed in details, and the suitable scope of application and rational parameters are determined, which are tested and verified through underground practice. The underground experience shows that slotting in the roof is suitable for roadway with high top pressure and low lateral pressure; and that the distance between the slotted floor to the roof of roadway should be equal to the width of the roadway.
