The Sandvik Mechanical Dynamic bolting system is faster and easier to install than conventional grouted rock bolts and provides improved ground support.
Designed and developed in Australia, the Sandvik Mechanical Dynamic Rockbolt (MD and MDX range) is a quick, easy, "one pass" application that can replace a range of ground support systems, including resin bolts, stiff split sets, and even cable bolting in some instances.
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.
