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:
apply and monitor inrush management plans on at least two occasions, including:applying inrush hazard controls, including:pumpingventilationsealsinrush control zonesprotective drillingaction levelsapplying inrush monitoring systems, including:continuous and/or periodic monitoringportable (hand held) monitoringcore samplesvisual observationgeological mapping borehole pressure readingsidentifying and controlling inrush hazards in a simulated environment.During the above, the candidate must:locate and apply relevant legislation, documentation, policies and procedures and confirm work activity is compliantimplement the requirements, procedures and techniques for applying and monitoring inrush management plans, including:interpreting, communicating and applying technical informationoperating hand held monitoring equipmentaccessing and interpreting data from monitoring systems and equipmentaccessing and interpreting design criteria for inrush prevention/management systems and devicesinterpreting computer spreadsheets and inrush modelling/simulationsaccessing and interpreting archival and historical inrush information related to the mineconducting enquiries/investigations and preparing audit reportswork effectively with others to apply and monitor inrush management plans that meet the required outcomes, including:organising work activities to meet task requirementscommunicating clearly and concisely with others to receive and clarify work instructionscomplying with reporting requirements and proceduresdetermining coordination requirements throughout work activities.
