<p>The invention relates to a fibreglass mining anchor for using in boreholes made in the roof and shoulders of underground tunnels of the mining industry. Advantages of the fibreglass mining anchor include the following: the flat base of the plastic nut permits an appropriate seat for adhering the mining plate to the rock mass; the fibreglass anchor is stronger than conventional anchoring elements, given that the combination of fibreglass and resin results in strength similar to that of steel; the anchor can be installed using manual and mechanical equipment; the dimensions of said anchor are in accordance with the requirements for the rock quality of the ground of each mine; the point of the rear end of the anchor serves to break and mix the contents of the cartridges arranged in the borehole; When detonating the explosives to obtain the mineral, the anchor disintegrates in such a way that the residue thereof does not damage the tyres of the vehicles or the belt conveyors used for processing the mineral. The anchor is installed together with the accompanying element, such as the mining plate, for high-strength reinforcement.</p> |
