La presente invención se refiere a un cartucho de resina que se inserta en perforaciones previamente hechas, utilizado preferentemente en la minería para la instalación de elementos de anclaje para el sostenimiento de terrenos y/o techos de faenas.  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.

OBJETIVO DE LA INVENCIÓN. OBJECTIVE OF THE INVENTION

Los cartuchos de resina son elementos fabricados para la instalación de pernos de anclaje que permiten ei sostenimiento de terrenos, con ios cuaies se aseguran el buen funcionamiento de las obras en el interior de la mina, para así asegurar a la vez, al personal que ingrese al interior de las minas. ANTECEDENTES. 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. BACKGROUND.

Existen cartuchos de cemento los cuales son utilizados para el reforzamiento de las anclas mineras que son instaladas en las obras subterráneas de la industria minera, estos se encuentran formados por una mezcla de conglomerantes hidráulicos ios cuaies tienen la mezcla adecuada entre cemento tipo portland y acelerantes los cuales permiten el fraguado para el sostenimiento de roca, este cartucho es utilizado en conjunto con agua, la cual es un elemento indispensable para la utilización de estos cartuchos cementantes, ios cartuchos cementantes deben hidratarse ai momento de su instalación para que estos fragüen una vez que son insertados en la perforación realizada previamente en el túnel subterráneo donde se requiere reforzar el macizo rocoso.  There are 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.

PROBLEMA TÉCNICO A RESOLVER. TECHNICAL PROBLEM TO BE SOLVED.

El problema que presentan los cartuchos cementantes es que demoran mucho tiempo al ser instalados, debido a que requieren del agua para ser hidratados para llevar a cabo su fraguado dentro de la perforación, lo que provoca una pérdida de tiempo operativo para ia instalación dei anclaje en ia roca, otro problema que presentan es que los equipos andadores con los que son instaladas las anclas mineras son deteriorados rápidamente, esto se debe a los cartuchos cementantes, ya que a! ser instalados presentan un derrame de material cementante que se va adhiriendo a los equipos andadores, por lo que requieren mantenimiento muy continuo para mantener en óptimas condiciones estos equipos. El cartucho de resina se instala sin el requerimiento de agua, esto se debe a que sus mezclas por ias que se encuentra formado permiten ei fraguado sin la necesidad de un elemento externo o catalizado, si no que este ya viene incluido en el envase del cartucho de resina, de tal manera que se instala e inmediatamente comienza su proceso de fraguado, su contenido no desprende residuos que se adhieran a ios equipos andadores por ¡o que estos grandes equipos no requieren de un mantenimiento de periodos frecuentes, lo que facilita la operación e incrementa la productividad para la extracción del mineral de las obras subterráneas de la industria minera. The problem presented by cementing cartridges is that they 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.
