Definitions

  • the present invention relates to a fiberglass mining anchor which is used as rock reinforcement in the underground works of the mining industry, is placed in the perforations made in the roof and shoulders of the underground tunnels of the mining industry and used in conjunction with accessories such as the cement cartridge or resin cartridge and the mining plate, which are inserted at the same time in the hole where the fiberglass mining anchor will be installed.
  • the fiberglass mining anchor is manufactured to be installed in the perforations previously made in the rock where the grounds are of poor quality and cause rockfall, which puts the health of the personnel operating in this type of underground works at risk,
  • the fiberglass mining anchor is installed to avoid the landslides of rock blocks which put the health of personnel entering the mine at risk.
  • Another objective of the elaboration of the fiberglass mining anchor is that it be used as a replacement for the anchors made of steel since this is made with resin-reinforced fiberglass which has the following benefits:
  • the problem presented by anchors made of steel is that they cannot be used in areas where explosives are detonated, since this causes the generation of metal parts (of the detonated anchor) which put into irrigation the proper functioning of the tires of the vehicles, conveyor belts of ore processing equipment and crushers.
  • the fiberglass mining anchor is made in such a way that it is used for the reinforcement of the rock mass for the safety of personnel and also where explosives are detonated in such a way that the anchor is disintegrated so that its parts do not affect or damage other devices that are part of the mineral extraction process of the mining industry.
  • the fiberglass mining anchor is made of fiberglass mixed with orange resin, which contains at the front end a standard thread section in which a nut made of resistant orange plastic is placed, the nut is attached to the fiberglass mining anchor by resin.
  • the length of the fiberglass mining anchor can measure from 1.6 meters to a length greater than 3: 0 meters according to the rock quality of the tunnels of the mine's underground works, the body of the fiberglass mining anchor It is scratched, which gives better adhesion to resin or cement cartridges with which this type of anchors are installed, its rear end has a 45 ° cut which serves to break the cartridges that are inside drilling when installing the fiberglass mining anchor.
  • the fiberglass mining anchor must have the mining plate in place before being placed in the hole to improve the support that is exerted on the rock mass.
  • FIG. 4 Detailed side view of the fiberglass mining anchor.
  • Figure 5. Rear upper isometric view of the fiberglass mining anchor without nut.
  • 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.
  • the mining plate 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.
  • the resin or cement cartridges For the installation of the fiberglass mining anchor, it is initially necessary to carry out a drilling in the rock that you want to reinforce in the tunnels of the underground works, the resin or cement cartridges must be thrown to the bottom of the drilling and then proceed to place the fiberglass mining anchor in the manual or mechanized equipment and the mining plate will be placed as a complement for the fixation and support of the rock mass, the manual or mechanized equipment inserts the anchor through the drilling through advance and rotation until ensure that the mining plate is adhered and fixed to the ground (rock mass).

Abstract

L'invention concerne un ancrage minier en fibre de verre, lequel est destiné à être utilisé dans des forages pratiqués au niveau du toit et des ogives des tunnels souterrains de l'industrie minière. Parmi les avantages présentés par cet ancrage minier en fibre de verre, on peut citer les suivants : la base plane de l'écrou en plastique permet d'obtenir un siège approprié pour faire adhérer la plaque minière à la masse rocheuse; l'ancrage offre une résistance supérieure par rapport aux éléments d'ancrage classiques en raison de la composition de la fibre de verre et de la résine qui permet de générer une résistance similaire à celle de l'acier; l'ancrage peut être installé avec des équipements manuels et mécaniques; les dimensions sont conformes aux normes requises pour la qualité de la roche des terrains de chaque mine; la pointe de son extrémité postérieure sert à rompre et à mélanger le contenu des cartouches disposées dans le forage; au moment de faire sauter les explosifs pour obtenir le minerai, l'ancrage se désintègre de façon que ses résidus n'endommagent ni les pneumatiques des véhicules ni les courroies de transport utilisées pour le traitement du minerai. L'ancrage est installé avec l'élément complémentaire, comme la plaque minière pour un renforcement haute résistance.
