The Fully-Grouted Cable Bolt (FGCB) was developed by the JENNMAR Sales Team after extensive field testing. The FGCB allows for a standard cable bolt to be fully encapsulated during installation or post-installation with polyurethane (PUR). A fully encapsulated cable bolt is better protected than a traditional bolt from corrosive elements that may be in a mine roof which could affect the cable bolt’s structural properties, especially if the cable bolt is subjected to these elements for prolonged periods of time. FGCB is available as a non-tensioned and INSTAL
® CC Tensionable Cable Bolt models.
Function
Although initially developed for corrosion protection, field trials demonstrated that the FGCB can act as a traditional PUR injectable bolt. The FGCB is proven to be very versatile roof support due to its ability to control many different ground conditions, from increasing the lifespan of standard cable bolt supports in long-term main entry systems to stopping the ingress of water and allowing access to previously unattainable reserves. The FGCB is a very effective and economical roof support option.
