Elements and Performance Criteria

Performance Evidence

The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including evidence of the ability to:

construct and maintain ventilation devices on at least two occasions, including:

applying basic construction skills to conduct remedial work to make workplace safe and to identify potential strata hazards (roof and ribs)

completing operations on the following devices in an underground coal mine:

stoppings or regulators; and

overcasts or undercasts; and

seals or bulkheads

using materials for devices, including, but not limited to:

poles/props/ply/mesh
