Application
This unit of competency specifies the outcomes required to use high-level design software program functions and features to produce mine drawings. The unit covers preparing the drawing environment by analysing project specifications; and setting up hardware, software, menus and drawing defaults accordingly. It also covers designing and creating mine drawings; producing drawing files that are saved in various formats; measuring and calculating mine volumes; and checking and validating the results to identify and resolve errors. The unit requires the ability to link drawing entities to database attributes and create and plot detailed views using various scales.
The unit supports those who work in a technical management role in a mining environment and take responsibility for liaising with clients and end users to meet project requirements.
Licensing, legislative, regulatory or certification requirements apply to this unit in some States where mining surveying must be undertaken under the supervision of a registered surveyor. Relevant state and territory regulatory authorities should be consulted to confirm those requirements.
