Definitions

  • the present invention relates to an apparatus for positioning a resin cartridge particularly, but not exclusively, for remotely positioning a resin cartridge in a hole in a mine roof.
  • mine roof is to be taken as including a reference to a mine wall, wall surface or a portion thereof.
  • rock bolts may be installed by firstly drilling a hole in the mine roof using a drill assembly provided on a drill boom which is manoeuvred on an articulated arm from a mining rig.
  • a resin cartridge is positioned in the hole and a rock bolt subsequently inserted to break the cartridge so that the resin sets about the bolt, thereby fixing the bolt in position.
  • Placement of the rock bolt in the hole may be achieved by using a second boom, allowing for maximum safety for both drilling the hole and inserting the rock bolt.
  • positioning the resin cartridge in the hole is largely effected manually, through use of a plunger fixed to a rod.
  • the combined length of the rod and cartridge make it generally unsuitable for mounting on a boom, particularly since a drive mechanism would also be required and the length dimension requirement of the boom would be exceeded. Accordingly, inserting the resin cartridge remains hazardous since workers are required to operate under an unsupported mine roof.
  • an apparatus for inserting a resin cartridge in a hole including: a drive unit; a plunger for driving the cartridge in a first direction; and a flexible linkage coupled to the plunger assembly, the linkage having a first portion, coupled to the plunger assembly, extending along a first path substantially parallel to the first direction, and a second portion adapted to extend laterally of the first portion, along a second path, wherein the drive unit is arranged to force the linkage in a direction from the second path to the first path to thereby drive the plunger assembly in the first direction.
  • the apparatus includes a guide assembly for guiding the plunger in the first direction, and for housing the cartridge prior to insertion in the hole.
  • At least part of the guide assembly is arranged to be located in the hole.
  • the linkage is formed of chain link.
  • the drive unit includes a drive sprocket for driving engagement with the chain link.
  • at least part of the second path is provided about the periphery of the drive sprocket and the first path is arranged tangentially thereto.
  • the chain link is configured so that the linkage bends in one direction, along the second path but is substantially rigid along the first path.
  • the apparatus includes an accumulator which stores a part of the second portion of the linkage prior to being fed onto the drive sprocket, the accumulator including a second sprocket arranged for the linkage to reverse direction around the periphery thereof for feeding onto the drive sprocket.
  • the apparatus is adapted to be fitted to a boom of a mining rig and includes an extension assembly for projecting the part of the guide assembly forwardly of the boom for location in the hole.
  • the guide assembly includes an elongate tube for housing the cartridge, the tube having at least an inner surface formed of polyethylene.
  • a boom with an apparatus as described above.
  • a method of fixing a rock bolt in a hole comprising: drilling the hole; inserting a resin cartridge using the above described apparatus; inserting a bolt into the hole to break the resin cartridge; and allowing the resin to set to thereby fix the bolt in the hole.
  • Figure 1 is a cross sectional view of an apparatus in accordance with the invention.
  • Apparatus 1 includes a drive unit 2, a plunger 3, a guide assembly 4 and a flexible linkage 5.
  • An accumulator 6 is provided for storing the linkage 5 prior to being fed to the drive unit.
  • the guide assembly includes a tube 7, a tube guide 8 attached to a remote end 9 of the accumulator, and an arbor 10 arranged to guide the flexible linkage into the tube 7.
  • the plunger 3 is located within the tube 7 and is coupled to an end 11 of the linkage 5 so that movement of the linkage 5 along a first path 12 results in corresponding movement of the plunger 3 in a first direction, indicated by arrow 13.
  • the tube 7 also serves to house a resin cartridge 14 for insertion in a hole formed in a mine roof (not shown).
  • the flexible linkage is formed of at least two portions 15, 16.
  • the first portion 15 extends along the first path 12, while the second portion extends laterally with respect to path 12, along a second path 17.
  • the flexible linkage 5 is formed by a chain link 18, which is configured so that the linkage bends in a direction of the second path but remains straight and substantially rigid along the first path 12.
  • the drive unit 2 includes a motor 19 and a drive sprocket 20 for engaging and driving the chain link such that the second path is defined at least in part about the periphery 21 of the drive sprocket 20.
  • the accumulator 6 is formed of an elongate casing 22 with parallel channels 23, 24 for housing the linkage 5.
  • a second sprocket 25 is provided adjacent the end 9 of the accumulator remote from the drive unit 2. The second sprocket 25 is arranged to allow the linkage to reverse direction from the channel 24, about the periphery 26 of the sprocket, into channel 23 for direct feed onto the drive sprocket 20.
  • the apparatus 1 may be provided on a separately manoeuvrable boom of a drill rig (not shown) or may be fitted to an existing boom, such as drill boom 30, for drilling the hole in which the cartridge is inserted.

  • the apparatus of the present invention allows the linkage to be stored laterally of the resin cartridge and the direction of insertion, thereby minimizing the overall length of the unit and providing a compact design which is suitable for use with a pre-existing or purpose built boom. Accordingly, the invention allows for resin cartridges to be remotely inserted in holes formed in a mine roof and further increases the safety afforded to mine workers.

Abstract

L'invention concerne un procédé et un dispositif permettant de fixer un boulon d'ancrage dans un orifice. Le dispositif comprend un mécanisme d'entraînement, un plongeur destiné à acheminer la cartouche dans l'orifice, et une liaison flexible couplée à l'ensemble plongeur. La liaison comprend une première partie couplée à l'ensemble plongeur, se prolongeant le long d'un premier chemin sensiblement parallèle à la première direction. La liaison comprend en outre une seconde partie apte à se prolonger latéralement par rapport à la première partie le long d'un second chemin. Le mécanisme d'entraînement est disposé de manière à forcer la liaison dans une direction partant du second chemin vers le premier chemin pour entraîner de ce fait l'ensemble plongeur dans la première direction. On fixe le boulon d'ancrage dans un orifice en perforant cet orifice, en insérant une cartouche de résine au moyen du dispositif précité, en insérant un boulon dans l'orifice pour rompre la cartouche de résine et en laissant que la résine se durcisse pour fixer le boulon dans l'orifice.
