With its unique wedge design, the Mechanical Dynamic bolting system is considered a permanent rock bolt that has been developed to provide strata support in a wide variety of rock conditions (weak and competent), and in particular, seismic rock conditions.
Many forms of ground support can be slow to install, and are a relatively rigid two-pass system, and as a result they are not suitable for dynamic ground conditions. In contrast, the MD Rock Bolt is a true dynamic bolt which can yield and withstand changing ground conditions.
Installation of the Sandvik bolting system is single-pass, without the need for post grouting.
