为了研究耦合支护控制巷道变形的效果,根据耦合支护原理,使用FLAC3D有限差分数值模拟软件对某矿11010工作面回风巷在不同支护参数下巷道的顶板、底板、左帮和右帮深部基点位移与围岩最大位移进行了研究.结果表明,当支护体与围岩以及支护体之间在强度、刚度、结构满足耦合支护时,巷道深部基点位移与围岩最大位移均较小,且巷道处于稳定状态所需时间较短.通过工程实例进一步说明了耦合支护能有效地控制巷道围岩变形,维护巷道稳定.

In order to research the effects of the roadway deformation controlled by coupling support,under the different support parameters,researched the displacement on the roof,the floor,the left,and the right,and the max displacement of the surrounding rock in a coal 11010 working face tailentry by FLAC3D numerical simulation software on the basis of the theory of coupling support.The result showed that the displacement of roadway deep point and the max displacement of the surrounding rock were both small,and the time which was needed to keep stable in the roadway when it was satisfied with the coupling support in between the support bodies and the surrounding rock,and among the support bodies.The engineering case furtherly stated that the coupling support could be effectively controlled the roadway rock deformation,and maintenance the roadway stability.
