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.
Claims14
A method for mining a narrow ore body in a mine having a mining chamber comprising the steps of:
- forming a raise which substantially follows the narrow ore body and is in communication with the chamber;
- providing a lift cage movable along the raise, the cage including a guide and mining equipment movably attached to the guide from which mining operations within the chamber can be carried out;
- suspending a plurality of guide rail sections from a roof of the chamber so that the guide of the cage can be aligned with the guide rail sections suspended from the chamber roof by appropriately positioning the cage in the raise to permit movement of the mining equipment from the guide to the guide rail sections;
- and
- moving the mining equipment along the guide and the guide rail sections;
- whereby ore can be mined with the working equipment as the equipment is moved along the chamber roof.
Apparatus for mining a narrow ore body in a mine having a mining chamber and a raise in communication with the chamber, the apparatus comprising:
- a lift cage mounted within the raise for movement along the raise, the lift cage including a guide and mine working equipment suspended from and movable along the guide;
- a plurality of guide rail sections suspended from a roof of the chamber so that the guide of the cage can be aligned with the guide rail sections by appropriately positioning the cage in the raise;
- and
- means for connecting the guide to the guide rail sections when they are in mutual alignment to permit movement of the cage along the guide and the guide rail sections, whereby ore can be mined with the working equipment as the cage and the equipment are moved along the chamber roof.
