摘 要:基于七一新发煤业有限公司北翼专用回风巷的地质条件,为防止出现底鼓的情况,对煤巷锚杆支护机理进行了研究,在底板岩石强度较低和顶板岩石易碎的情况下,设计了高强度锚杆锚索联合支护系统,主要简要的介绍了锚杆和锚索支护的设计思路,并对支护的效果进行了监测。工程实践表明:锚杆锚索联合支护,能有效的控制围岩的变形和维持顶板的完整性。Based on geological conditions of north wing of Qiyi Xinfa Mining Industry exclusive return airway, in order to prevent the bottom heave, mechanism of bolt supporting in coal roadway was studied, under the condition of lower floor rock strength and fragile roof rock, high strength bolt anchor combined support system was designed, the design of the anchor rod and anchor rope support ideas were mainly introduced, the support effect was monitored.The engineering practice showed that anchor rod anchor combined support could effectively control the deformation of the surrounding rock and maintain the integrity of the roof.
