锚网喷注耦合支护在深部软岩巷道的应用

深部软岩巷道一直是巷道支护的难点。目前,由于软岩巷道不能为锚杆提供可靠的着力基础,因此软岩巷道的可锚性差。锚杆和注浆都是巷道等岩土工程支护的基本形式。利用锚杆兼做注浆管,在一次锚网喷支护的基础上,实现"锚注一体化"是解决这一难题的一条新途径。

Application of Combined Support with Bolt Net and Shotcrete Spray in Deep Soft Rock Roadway

The support of deep soft rock roadways is always a difticult point of roadway support.At present,the soft rock roadways can not privde the reliable force basis for bolts,so the anchor nature is bad.Anchor and spay both are the basis form of geotechnical engineering support.Taking advantage of bolt-grounting pipe,on the basis of a mesh support,realizing "bolting integration" is a new way of resolving this difficult problem.
