锚网索联合支护作为现行巷道支护的一种有效方式,其锚索作为加强支护,锚索支护参数确定在一定程度上能提高支护的可操作性、实用性和可靠性,锚索支护参数主要是根据巷道围岩的物理力学性质、所处的应力状况以及采动影响,来确定锚索的孔径、锚固段长度、锚索的长度、间排距以及布置形状,通过锚索与围岩形成的有效承载体来进行软岩巷道锚索支护参数设计。
As an effective way to support the existing roadway, the combined support of anchor and wire mesh can effectively improve the maneuverability, practicability and reliability of the support by using the anchorage cable as strengthening support and the anchoring parameter of anchorage cable to some extent. The parameters of anchor cable support mainly determine the diameter of anchor cable, the length of anchor cable, the length of anchor cable, the spacing between the cables and the arrangement shape according to the physical and mechanical properties of the surrounding rock of the roadway, the stress status and the mining influence, An effective bearing body formed by the anchor cable and the surrounding rock is used to design the anchor cable supporting parameters in the soft rock roadway.
