  • Patent number: 5007683
    Abstract: For narrow ore mining, shrinkage stopping is used with working equipment, such as a working platform or mining rig (30), which is suspended in guide sections (38) in the roof of the mining chamber, and from which drilling and charging is carried through, the mining chamber communicating with a raise. In the raise, which follows the inclination of the ore body, a transport lift is used designed for receiving the working platform or mining rig (30) in its lift cage (20). The lift cage (20) comprises a transport guide arranged for suspension of the working platform or the mining rig in the lift cage and connectable to a start guide in the roof of the mining chamber.

  • Patent number: 4960175
    Abstract: An assembly for raise mining or the like includes a drive support carrying a drive means (10) for driving the drive support along a guide (4). The guide is attached to the drift wall (2) and is successively lengthened concurrently with the drift driving.
