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.
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 a 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.
