Performance Evidence

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

• locates and applies relevant legislation, documentation, policies and procedures
• implements the requirements, procedures and techniques for the safe, effective and efficient completion of inrush management plan application and monitoring including:

• reading, interpreting, communicating and applying technical information
• operating hand held monitoring equipment
• accessing and interpreting data from monitoring systems and equipment
• accessing and interpreting design criteria for inrush prevention/management systems and devices
• interpreting computer spreadsheets and inrush modeling/ simulations
• accessing and interpreting archival and historical inrush information related to the mine
• conducting enquiries/investigations and preparing audit reports
• identifying training needs, and preparing and implementing training plans

• works effectively with others to plan, prepare and conduct the application and monitoring of the inrush management plan that meets all of the required outcomes including:
• organising work activities to meet all task requirements
• communicating clearly and concisely with others to receive and clarify work instructions
• complying with written and verbal reporting requirements and procedures
• resolving coordination requirements throughout work activities
• demonstrates consistent timely completion of inrush management plan application and monitoring that safely, effectively and efficiently meet all of the required outcomes on a minimum of one (1) occasion including:
• applying inrush controls such as:

• controls that eliminate the hazard by removing the damaging energy, e.g. drainage including pumping and ventilation
• controls that reduce the magnitude of the hazard (less water, less pressure etc), e.g. drainage, including pumping and ventilation
• controls that reduce the likelihood of the event through engineering or hard barriers, e.g. seals
• controls that reduce the likelihood of the event through procedural or soft barriers, e.g. establishment of inrush control zones, protective drilling
• controls that reduce the likelihood of the event through warnings, e.g. action levels associated with increased water make

• applying monitoring systems such as:

• continuous and/or periodic monitoring
• portable (hand held) monitoring
• core samples
• visual observation
• geological mapping
• borehole pressure readings

• identifying and controlling inrush hazards such as:

• continuous and/or periodic monitoring
• portable (hand held) monitoring
• core samples
• visual observation
• geological mapping
• borehole pressure readings

Knowledge Evidence

• faults, dykes, intrusions and strata deformities

• identifying and using monitoring systems and techniques including:

• fixed monitoring systems: types, uses / limitations, design criteria, specifications and design processes
• portable monitoring equipment: types, uses/limitations
• processes and techniques for determining alarms and trigger points/levels
• methods of control of inrush

Assessment Conditions

• An assessor of this unit must satisfy the requirements of the NVR/AQTF or their successors; and Industry regulations for certification and licensing; and,
• this unit must be assessed in the context of this sector’s work environment; and,
• this unit must be assessed using Resources and Infrastructure Industry sector specific policies, procedures, processes and operational manuals; and,
• an assessor must demonstrate the skills and knowledge of this unit through twelve (12) month work experience in an Industry relevant to the skills being assessed within the last three (3) years; and,
