Abstract:
A conveyance system for moving a conveyance along a mine shaft during shaft construction, comprising: a first guide section; a second guide section located along the mineshaft in series with the first guide section, the conveyance being movable along the first guide section; and a head section for receiving the conveyance, the head section cooperating with the first guide section to enable the conveyance to travel from the second guide section along the first guide section when received by the head section.
Abstract:
In developing an underground mine a mine shaft (80) is formed by excavating earth and removing excavated material from the shaft (80) by a material transport system comprising skips (36) movable up and down on skip guides within the shaft. Tunnels (82) are launched from a bottom part of shaft (80) by excavating a cavern (81) in which a tunnel boring machine is assembled and operated to bore the tunnels (82). Material from the tunnel excavation is transported from the tunnels via conveyor (87) to the material transport system established within the shaft during formation of the shaft which is operated to transport that material to an earth surface region.
Abstract:
The invention provides a guide rail section (200) for a guide rail for guiding displacement of a conveyance in a mine shaft, the guide rail section (200) including a longitudinally extending guide formation (14) and a retractable latch (24) for connecting the guide rail section (200) to another such guide rail section (200) adjacent thereto, the latch (24) being movable between an extended position in which the latch (24) projects beyond an end (21) of the guide rail section (200) and a retracted position in which it does not project beyond the end (21). The invention extends to a method of connecting the guide rail section (200) to another such guide rail section (200). The invention extends further to a guide rail which includes a plurality of the guide rail sections (200) connected to one another.
Abstract:
A variable length guide system for guiding a conveyance along a mineshaft, the variable length guide system extending downwardly from a work stage and being extendable or retractable to accommodate changes in distance between the work stage and a lower region of a mineshaft.
Abstract:
A method of moving a component or a material to and within a level of a shaft boring system. The shaft boring system is positioned within a shaft and the method comprises lowering the component or the material inside a cage into the shaft and to a level of the shaft boring system. The method further comprises suspending the component or the material from a transport system within the level of the shaft boring system. In addition, the method comprises moving the component or the material within the level of the shaft boring system using the transport system. The component is a component of the shaft boring system and the material is a material for forming the shaft boring system.

Abstract:
The present invention concerns an arrangement for the fastening of lift shaft equipment to a wall in a mine shaft for a personnel lift, the equipment comprising at least one rail that extends in the longitudinal direction of the shaft, on which rail a lift car can run, and fixtures for the mounting of the rail at a predetermined distance from the wall of the shaft. The fixture comprises an extended beam with means that can be adapted to the angular deviation of the wall of the shaft relative to the longitudinal direction of the beam.
