A new vertical shaft has been proposed to connect surface to existing workings at a depth of 1000m below ground. The shaft is to be a mineral hoisting shaft with the ability to act as an emergency egress and has a proposed circular shape of 6m diameter. The stratigraphy of the geological strata at the shaft site is as follows:

Depth from surface	Strata type
0-20m	Soil/overburden
20-100m	Weak regolith
100-300m	Siltstone of moderate strength low water flow
300-400m	Impermeable shale of moderate strength
400-800m	Bunter sandstone of high strength, aquifer, high water flow
800-1000m	Shales, medium strength, low water flow

The purpose of the exercise is for students to develop a shaft sinking and lining strategy for the site. The expectation is for students to compile a report of their findings, the report should include:

Proposed excavation strategies
Timelines/project management for the project
Equipment and consumables used
Costing's ( a useful source is the AusIMM monograph 'Cost estimation handbook')
lining design
sinking stage design
shaft fittings

and any other salient points.
