Definitions

  • a method and an apparatus for raise mining are provided.
  • the present invention relates to a method for raise driving in which the driving is performed from equipment that is movable along a guide rail applied on the wall of the raise, said guide rail being lengthened as the work proceeds, includes a drill rig by means of which blasting holes are drilled in the upper end face of the raise, and a platform, from which staff can perform manual work such as loading of the blast holes.
  • apparatus for raise mining including equipment that is movable along a guide rail applied on the wall of the raise, said guide rail being lengthened as the work proceeds, includes a drill rig by means of which blasting holes are drilled in the upper end face of the raise, and a platform, from which staff can perform manual work such as loading of the blast holes. State of the art.
  • the so-called Alimak method for raise mining was introduced in 1957 together with the raise climber.
  • the Alimak method consists of five steps together forming a cycle. The five steps are all performed by means of the raise climber which has a working platform and serves as a transport means along the raise from a protected bottom station up to the work site, i.e. the upper end of the raise. More particularly, the raise climber runs on a guide rail which is anchored to the hanging wall of the raise and successively lengthened as the work proceeds.
  • drilling holes to be charged with explosives is done.
  • the drilling is performed from the working platform which is designed to suite the size and shape of the raise climber.
  • the fourth step which is shooting, i.e. blasting of the bursting set applied in the drill holes, is preceded by the raise climber being moved down to the bottom station which is located at the lower end of the raise so as to be protected against falling rock due to the blasting. Thereupon the bursting set is triggered from the bottom station.
  • the fifth step ventilation is performed, i.e. blasting gases are cleared.
  • nitrogen gases and dust created by the blasting are removed by spraying a mixture of water and air from the top of the guide rail. Both water and air are supplied through pipes extending in the guide rail.
  • a first object of the invention is to provide a method and apparatus for raise mining that combines an appreciately higher efficiency and driving speed than what has been possible to attain thus far, with a considerable improvement of the working environment.
  • a second object of the invention is to provide a method for raise mining during poor rock conditions, which is considerably safer than what has been possible thus far.
  • the first object has been attained in that a round cycle that includes the total time after blasting of a round up to blasting of the next round, comprises in turn the steps: a) simultaneous drilling and ventilation, b) guide rail lengthening followed by loading, c) blasting.
  • the second object has been attained in that drill rig and platform consist of two separate, on the guide rail separately drivable units, and that a round cycle that includes the total time after blasting of a round up to blasting of the next round, according to a first alternative comprises in turn the steps: a) ventilation, b) rock reinforcement from the platform, c) drilling of blast holes from the drill rig, d) guide rail lengthening followed by loading from the platform, e) blasting, according to a second alternative comprises in turn the steps: a) ventilation, b) rock reinforcement and guide rail lengthening from the platform, c) drilling of blast holes from the drill rig, d) loading from the platform, e) blasting.
  • the above mentioned objects have been attained in that the drill rig is designed for unmanned action, the drill rig and the platform consist of two separate units which are separately drivable on the guide rail, shifting means are provided for admitting removal of either of the units from the guide rail and shifting on the other unit.
  • a completely remotely controlled drill rig without crew is sent up in the raise directly after the preceding round has been fired. Ventilation is started simultaneously and visibility conditions at the raise top are therefore considered to be completely acceptable for visual control by means of a television camera/monitor when the rig arrives at the drift top.
  • the movements of the drill boom can be computer controlled according to a determined drilling plan.
  • the movements of the drill feeder and the starting and stopping impulses of the drill rig can either be remotely controlled, or these movements as well as start and stop impulses can be integrated into the data program.
  • the drill rig After finished drilling the drill rig is moved down to the bottom and is shifted out of the guide rail path.
  • a specially designed working hoist is shifted into the guide rail path equipped with brackets for one or more new guide rail sections and mechanically arranged drilling equipment for drilling holes for anchoring bolts, and reinforcing bolts, if any, into the rock wall. From this working hoist guide rail lengthening/loading is performed by one or two men who also make necessary inspection of the rock surfaces for taking decisions regarding reinforcing works, if any.
  • the lift is moved down to the drift floor.
  • Blasting is performed remotely controlled from the drift bottom by means of equipment according to the Nonel system, in which initiation is carried through by means of compressed air without use of electrical signals, whereby unintentional initiation from the electric system of the equipment is completely eliminated.
  • the invention has a number of advantages. It is advantageous from a working environment point of view that no crew at all is present in the drift during the drilling work. There is, however, possibility for inspection of rock surfaces and reinforcement by crew being in the shaft for guide rail lengthening and loading, the shaft having been effectively ventilated before this working step during the earlier working step.
  • the drill rig can now, without increase of dimensions and claims for a lowest weight, decided for security reasons, be equipped with a very forceful drill machine, which should reduce the drilling time. This in turn guarantees a considerably higher efficiency/driving speed which well justifies the cost increase due to the drill machine.
  • the drill steel length and thereby the duration of the round should be able to be considerably lengthened in the long run, as compared to that being the case earlier in connection with raise mining with manual drill machines, and also be able to be adapted to rock quality and raise dimensions.
