Definitions

  • the present invention relates to a slotted tube and rod 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, shoulders and lateral walls 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 drilling where the grooved pipe and rod mining anchor will be installed.
  • the mining anchor of grooved pipe and rod is manufactured to be installed in the perforations previously made in the rock where the grounds are of poor quality and cause rock shedding, which puts at risk the health of the personnel operating in this type of underground works , the mining anchor of grooved pipe and rod is installed to avoid the landslides of rock blocks which put the health of personnel entering the mine at risk.
  • the problem presented by the mechanical anchors used in the underground works of the mining industry is that they are easily damaged by the mass (weight) of the blocks of the different sizes and that it generates a low resistance for the reinforcement of the rock mass that is it requires to avoid the irrigation in the health of the personnel that enters the underground works of the mining industry.
  • the slotted tube and rod mining anchor is installed in the perforations previously made in conjunction with the cementing cartridge or resin cartridge and a mining plate to generate a sturdy reinforcement and support such that the blocks do not come off because they are reinforced
  • the ring welded on the front end in omega type serves as a stop and support for the mining plate, so that it sits properly on the front end of the mining anchor of grooved pipe and rod and that it does not break easily letting it exert its resistance to deformation better.
  • the mining anchor of slotted tube and rod is made of slotted tube or tube type "C" and corrugated steel rod, which contains at the end welded front a wire rod or a sheet ring (plate) for which both rings have the function of supporting the mining plate that complements the slotted tube mining anchor and rod for the reinforcement of the rock mass in the tunnels of the mining industry , the aforementioned ring is attached at the tip of the slotted tube by means of welding, the union that exists at the center of the anchor is by means of welding, where the slotted tube and the corrugated rod are joined which forms the rear end, the end of the grooved tube that joins the corrugated rod has taper such that the corrugated rod can be welded in its contour, at the rear end it has a 45 ° cut which allows to be installed to break the cartridges that were previously inserted In drilling, the slotted tube and rod mining anchor is placed in these perforations with manual or mechanized equipment, and is by advance and percussion (I hit cannulated) towards the bottom of the hole, before

  • the mining anchor of slotted tube and rod is formed of two parts, the first one (2: Figure 2) is made of slotted tube or type "C" tube which is installed in pre-drilled holes in the underground tunnels of the mining industry to reinforce the ground and allow time for the cartridges placed at the bottom of the drilling to set, which are used to reinforce the second end (3: Figure 2) of the slotted tube and rod mining anchor, this second end is made of corrugated steel rod, which in turn has a tip with 45 ° cut (4: Figure 2) that works as a tool to break the cartridges and allow their contents to be mixed for setting and anchoring the anchor.
  • the slotted tube and rod mining anchor has a ring welded on the front end (6: Figure 1), the function of this is to improve the placement of the plate at the time of installation, as it serves as a seat for proper adhesion and for better use the resistance generated by the mining plate for the support of the rock mass where it is installed.
  • the resin or cement cartridges For the installation of the slotted tube and rod mining anchor, it is initially necessary to perform a drilling in the rock that is desired 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 will proceed to place the mining anchor of slotted tube and rod 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 into the drilling the anchor through advance and percussion until the mining plate is adhered and fixed to the ground (rock mass).

Abstract

La présente invention concerne un ancrage minier à tube rainuré et tige destiné à être utilisé dans des forages effectués dans le plafond, les accotements et les murs latéraux des tunnels souterrains de l'industrie minière. Parmi les avantages de cet ancrage minier à tube rainuré et tige il convient de considérer: - l'anneau soudé en face de l'extrémité frontale assure un support adéquat pour faire adhérer la plaque minière au massif rocheux; la génération d'une résistance supérieure aux éléments d'ancrage classiques du fait qu'il existe deux manières efficaces d'assurer la sécurité du personnel, la première étant immédiate au moment de l'installation par le frottement généré par le tube rainuré et la seconde liée au renforcement une fois la prise des cartouches qui sont insérées dans la perforation. Il peut être installé avec des moyens manuels et mécanisés; - les dimensions sont conformes aux conditions de qualité de la roche des terrains de chaque mine. - la pointe de son extrémité postérieure sert à briser et mélanger le contenu des cartouches placées dans la perforation.; il est installé en combinaison avec la plaque minière pour assurer un renforcement à haute résistance.
