Definitions

  • the present invention relates to a mining anchor with pointed thread which is used as rock reinforcement in the underground works of the mining industry, is placed in the perforations made in the rock and used in conjunction with accessories such as cement cartridge or cartridge of resin that are inserted in the perforation, and the mining plate which is placed in the anchor for the reinforcement of the rock mass.
  • the mining anchor with pointed thread 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 at risk the health of personnel operating in this type of underground works.
  • the mining anchor with pointed thread is installed together with resin or cement cartridges in a previously made drilling, and will be placed to the bottom of it
  • the rock plate continues, so that the rock mass is reinforced by leaving the mining anchor and the mining plate butt with the rock to prevent the rock from detaching, avoiding jeopardizing health of the personnel that operates in this type of underground works, another problem that it solves is to be able to be adjusted when it requires maintenance, since it can be the case that there is rock detachment in the perimeter near the mining anchor with pointed thread, of such that it can be adjusted by means of the nut to adhere properly to the rock once it is no longer next to the rock massif, preventing the blocks of rock from giving in.
  • the mining anchor with pointed thread is made of forged steel and manufactured by the process of forming the red-hot steel applied on the tip on a corrugated steel rod, the back of the anchor that has the corrugated serves to adhere properly to the mixture of the cartridges with which it is used. It is made in lengths ranging from 1.60 meters to lengths greater than 3.0 meters, has 8 "(20.32 mm) of thread at the front end, and handled in diameters of 5/8" (1.58 mm) and 3/4 "(1 .90 mm). The nut can travel the length of its thread to be adjusted in areas that are of very poor quality or very unstable.
  • the mining anchor with pointed thread is installed in perforations previously made in the tunnels of the underground works of the mining industry, together with its complements which can be resin cartridges or cementing cartridges, and with the mining plate that supports the rock mass of the underground works of the mining industry.
  • This type of anchor has a 45 ° cut at the rear end that serves to break and mix the cartridges a! time to get into drilling.
  • At the front end, at the front of the thread has the square formation, this helps you to be able to hold it from the walking equipment to install it in the hole.

  • the mining anchor with pointed thread (Figure 1) is made from corrugated steel rod, to which an ACME type thread (1: Figure 4) is made, which is a standard rectangular or square 8 "thread ( 20.32 mm) in length of the mining anchor, which prevents damage to it so that it operates properly when it is installed and requires maintenance.
  • the mining anchor with pointed thread can be made in lengths ranging from Sos 1 .6 mts up to length greater than 3.0 meters, and this is according to the quality of the rock of the rock mass, being that if it is of good quality they will be of smaller size and if the terrain is of bad to very poor quality they will require a longer length
  • the recommended diameter for this type of mining anchor is 3/4 "(19.05 mm).
  • a drilling is carried out in the underground work of the mining industry, resin or cement cartridges are inserted inside the drilling, then the mining anchor with pointed thread is placed in the equipment manual or mechanized that will insert it into the drilling and the mining plate is inserted into e! Anchor, the mining anchor is then inserted with a pointed thread to the bottom of the hole, so that the plate placed at the front end is properly adhered to the rock mass to avoid the release of rock that puts at risk the health of the personnel that operates in this type of underground works of the mining industry.
  • the mining anchor with pointed thread Once the mining anchor with pointed thread is placed in the rock mass, it will be checked periodically, so that it is checked whether rock falls have been carried out in the near perimeter of the mining anchor with pointed thread, if this happens it should be adjust the nut until the mining plate adheres until it is again adhered to the rock mass to maintain the resistance to avoid rock falls.

Abstract

La présente invention concerne un ancrage minier comprenant un filet sur la pointe afin de pouvoir être utilisé pour le renforcement des terrains souterrains de l'industrie minière afin d'assurer la sécurité du personnel. Parmi les avantages de cet ancrage minier à filet sur la pointe, on trouve que: - il évite les détériorations du filet du fait de sa taille et de sa rigidité; - il permet d'ajuster la plaque minière avec l'écrou même après l'installation de l'ancrage minier à filet continu et après l'éboulement de roches dans le périmètre proche de l'ancrage. - il comporte un cadre en acier à l'avant de l'ancrage qui permet de l'installer facilement du fait qu'on utilise un dé pour sa mise en place. Il est installé en combinaison avec les compléments que sont: la cartouche de liant ou de résine et la plaque minière pour assurer un renforcement adéquat de la roche des tunnels souterrains de l'industrie minière.
