Definitions

  • Rocks and especially minerals are usually mined by drilling and shooting - with the known disadvantages.
  • Activation from the inside or outside means that disks, discs or the like - with or without teeth - can be activated on the inside, e.g. by eccentric, or the entire drilling tool from the outside e.g. impacted by eccentric or unbalance impact devices - and thus activated.
  • the pressure forces required here are only 10% of those required for conventional drilling
  • the self-controlling unit not only has the advantage that it does not require any control electronics or a man to maintain the undercut depth, but that the drilling material can be freely picked up behind the drilling tools, ie it can be removed.
  • FIG. 1 shows, under 1, the undercutting, removing, rotating, disc or disc tool, 2 is the motor-driven rotating or swiveling arm of the drilling tool, 3 the rock contour before the undercut and 4 after the undercut - the arrow is a direction of advance.
  • FIG. 2 7 is again the disc or disk tool and 8 is a rotating or oscillating arm, 9 is the stone front before and 10 after removal - according to FIG. 1 - only in a different view.
  • Drilling tools of this type are known per se from DE-B-1.233.806
  • 11 is a conventional feed device and 12 is the rotating drill head which is motor-driven in this embodiment and has a plurality of disc or disk tools - here arranged in a line and undercutting / removing only one layer.
  • the drilling head can be centered overall - or the drilling tools can be activated individually. According to the invention, the specific contact forces in this system are incomparable and therefore more advantageous than with a disc of the diameter of the removal height.
  • 13 are the rotating, undercutting, cutting and / or milling / striking disc drilling tools that undercut each in several layers
  • 14 are holders for this and 15 is the motor-driven shaft.
  • the tools 13, which operate in stages and split in stages, have unequally long brackets which are evenly distributed on the shaft 15.
  • the dismantling front 16 or direction is shown in a view from above.
  • - 17 is the traction device, a hydraulic ram with traction cylinder braced in the hanging and lying position.
  • 18 is a runner, which can also be replaced by wheels / castors - or locked in place from stroke to stroke - but then by sending a separate lifting / pushing / swiveling device.
  • 19 is the pressure device - pivotably mounted on the hydraulic ram - see arrow 20.
  • 21 is a motor-activated disk-type milling drilling tool - 21a is the one working in a second stage. Separate protection is required for slight angling to reduce wear.
  • the system explained above can of course also be used to remove horizontal layers - for example, to remove road surfaces in layers.
  • FIGS. 6 and 7 show how, in particular, pre-drilled holes are expanded radially from the inside to the outside with the claimed technique of undercutting removal - but especially also for drilling arch profiles.
  • 29 is the holding and turning device in the pilot hole
  • 30 is a version of a scaring rolling or striking but also conventional undercutting disc / disc tool.
  • 31 is the rock contour before the undercutting
  • 32 is the extendable, slowly rotating hydraulic cylinder driven by 29 and held from cut to cut without feed when expanding a pilot hole.
  • FIG. 7 shows a system for subsequently boring / expanding circular tunnel bores to form an arc profile.
  • 33 is a driven - possibly activated drilling head with 3 disc roller drilling tools.
  • 34 represents a single activated roller drilling tool that i.a. also drill on the spot - so you can also drill out the corners of the arch profile without any problems.
