Abstract

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.

El ancla minera de fibra de vidrio (Figura 1 ) es manejada en longitudes que van de los 1.60 mts hasta unas longitudes mayores a 3 mts, según el tipo y la calidad de roca de los terrenos en cada mina, de tal manera que donde esta de muy mala calidad el terreno utilizan las anclas de mayor longitud y donde se encuentra el terreno de mejor calidad de roca utilizan las de menor longitud. El ancla minera de fibra de vidrio se encuentra formada de dos partes, la primera es una tuerca elaborada de plástico color naranja (Figura 6) la cual es insertada en la parte frontal del ancla de fibra de vidrio y es pegada mediante resina para dejarla fija, la tuerca es insertada en la rosca estándar (1 : Figura 4), el objetivo de la tuerca es para brindar un soporte adecuado en el perímetro del ancla donde se junta con la tuerca para ser colocada y adherida al macizo rocoso, el cuerpo del ancla se encuentra rayado (2 : Figura 4) la cual sirve para una adecuada adherencia a los cartuchos cementantes o de resina que se encuentran en el interior de la perforación, su extremo posterior del ancla minera de fibra de vidrio cuenta con punta con corte a 45° (3 : Figura 4) que funciona como herramienta para romper los cartuchos y permitir que su contenido sea mezclado para el fraguado y sujeción del ancla. The fiberglass mining anchor (Figure 1) is managed in lengths ranging from 1.60 meters to lengths greater than 3 meters, depending on the type and quality of the rock of the land in each mine, so that where it is of very poor quality the ground uses the anchors of greater length and where the best quality rock terrain is located they use those of shorter length. The fiberglass mining anchor is formed of two parts, the first is a nut made of orange plastic (Figure 6) which is inserted in the front part of the fiberglass anchor and is glued by means of resin to leave it fixed, the nut is inserted in the standard thread (1: Figure 4), the purpose of the nut is to provide adequate support on the perimeter of the Anchor where it joins the nut to be placed and adhered to the rock massif, the anchor body is scratched (2: Figure 4) which serves for adequate adhesion to cement or resin cartridges that are inside drilling, its rear end of the fiberglass mining anchor has a 45 ° cut tip (3: Figure 4) that functions as a tool to break the cartridges and allow their contents to be mixed for setting and anchoring the anchor.

Antes de ser colocada el ancla minera de fibra de vidrio se debe colocar la placa minera de modo que al instalarse ya pueda quedar junta o adherida adecuadamente al macizo rocoso para evitar el desprendimiento de roca de los túneles subterráneos de la mina. Before the fiberglass mining anchor is placed, the mining plate must be placed so that when installed it can already be properly attached or adhered to the rock mass to avoid the rock detachment of the underground tunnels of the mine.
