Some time later, in the middle of my day shift at the Steward mine, I was told to report to the shaft station
to be hoisted to the top.
Above tenth level, there were several escape routes but 625 feet below, where the shaftmen mucked, drilled and blasted the shaft deeper, there was no other way out than to climb the ladders through the smoke and past the fire which started right at the shaft station
Each emplacement room is 10 m wide by 4 m high by 91 m long; the most restrictive access drift between the waste shaft station
and emplacement area is 6 m wide by 3.
3 Shaft Station
in the immediate footwall of the Polaris Fault, and is potentially related to an existing resource of 10,200 tons grading 25.
The first shaft station
was developed on the 305 m level and others will be excavated every 305 m below that.
Excavation of the Level 6 shaft station
and loading pockets is underway, to be followed by drifting along the level and stope preperation.
To get around the problem of the shaft capacity constraint, MBT proposed dropping pre-mixed concrete down a steel pipe the full 2,300 m from the surface to the shaft station
, so delivering a continuous supply of high-performance, steel fibre-reinforced shotcrete that could be sprayed at any time during the working shift.
Once underground it was assembled by the FKC/DH project team at the shaft station
on 3440 Level.
The primary work areas--drill chamber, shaft stations
, and main roads--were shotcreted to forestall potential weathering.
3] during the excavation of 17 shaft stations
, two loading pockets, four lip pockets and two mid-shaft chairs.
In addition, related underground infrastructure such as shaft stations
, loading pockets and drift access will be completed.
