Definitions

  • the present invention relates to a resin cartridge that is inserted in previously made perforations, preferably used in mining for the installation of anchoring elements for the support of terrains and / or work ceilings.
  • Resin cartridges are elements manufactured for the installation of anchor bolts that allow the maintenance of land, with which the proper functioning of the works inside the mine is ensured, in order to ensure, at the same time, the personnel entering inside the mines.
  • cement cartridges which are used for the reinforcement of the mining anchors that are installed in the underground works of the mining industry, these are formed by a mixture of hydraulic binders ios which have the proper mixture between portland cement and accelerators. which allow the setting for the support of rock, this cartridge is used in conjunction with water, which is an essential element for the use of these cementing cartridges, the cementing cartridges must be hydrated at the time of installation so that they set once they are inserted in the drilling previously carried out in the underground tunnel where it is necessary to reinforce the rock mass.
  • cementing cartridges take a long time to be installed, because they require water to be hydrated to carry out their setting within the perforation, which causes a loss of operating time for the installation of the anchorage in ia rock, another problem they present is that the walking equipment with which the mining anchors are installed are deteriorated rapidly, this is due to the cementing cartridges, since a! being installed they present a spillage of cementitious material that adheres to the walking equipment, so they require very continuous maintenance to keep these equipment in optimal conditions.
  • the resin cartridge is installed without the requirement of water, this is because its mixtures by which it is formed allow the setting without the need of an external or catalyzed element, if this is already included in the cartridge container of resin, in such a way that it is installed and immediately begins its setting process, its content does not give off residues that adhere to the walking equipment because these large equipment does not require maintenance of frequent periods, which facilitates the operation and increases the productivity for the extraction of the mineral from the underground works of the mining industry.
  • Resin cartridges are manufactured based on a mixture of a polyester resin putty and a chemical catalyst, the resin and the catalyst are wrapped by a transparent plastic film of polyethene, which has an internal separator made of the same material. which avoids the mixing of these components so as not to cause their reaction or setting before installation in the drilling of the underground tunnels of the mining industry.
  • the resin cartridge is made of varied diameters from 15 mm to 45 mm and of varying lengths from 250 mm to 800 mm.
  • the wrap is closed by an aluminum clasp at each end such that the final product has a sausage shape.
  • Figure 4. Isometric front of the resin cartridge with cut in the container. DETAILED DESCRIPTION OF THE INVENTION.
  • the resin cartridge has an aluminum clasp (5: Figure 3) with which the container is closed at its two ends so that the internal elements are protected to prolong the durability of the resin cartridge when it is stored.
  • the resin cartridge ( Figure i) is made of varied diameters ranging from 15 mm to 45 mm and of varying lengths from 250 mm to 800 mm.
  • the resin cartridge ( Figure 1) is used for the reinforcement of the rocks detached from the rock mass of the mines, which are prone to fall, for its installation a drilling in the rock solid mass to be reinforced must be carried out, of tai so that the depth is according to the length of the anchor to be installed, once the drilling is done, the resin cartridges are launched ( Figure 1) to the bottom of the drilling by means of the walking equipment, in such a way that are sufficient to fill the perforation and to cover the entire area of the anchor length to be installed, so that the mixed resin (1: Figure 4) can hold the rock mass along the anchor inserted in the perforation.
  • the anchor is inserted by rotation in the perforation, so it breaks the Inserted cartridges and mix the components contained in the cartridge to begin the process of its chemical reaction or setting. Once the cartridges are inserted into the perforation and the anchor attached, it will take 30 minutes for the necessary resistance to support the rock blocks that is an average of 8 to 10 Tons, the average total resistance generated by the resin to be achieved. with a mining anchor of 2.60 meters is 18 tons. The resistance may vary according to the quality of the rock, the way of installation and the length of the mining anchor.

Abstract

La présente invention porte sur une cartouche de résine destinée à être utilisée de préférence dans le domaine minier, pour l'installation d'éléments d'ancrage servant au renforcement de la roche détachée du massif rocheux lors de travaux souterrains dans l'industrie minière. Parmi les avantages présentés par cet ancrage minier, on peut citer les suivants: Application sûre dans les perforations, et rapide. Résistance élevée après adhérence à la roche. Empêche la formation de fissures nuisant à la stabilité de la roche. Empêche la corrosion de l'ancrage installé. Résiste aux vibrations provoquées par la détonation d'explosifs dans les galeries souterraines.
