Unit of competency

Modification History

Application

This unit describes the skills and knowledge required to implement inrush management plans in coal mining, including implementing and reviewing inrush hazard controls and protection measures for personnel, services and infrastructure.

This unit is appropriate for those working in supervisory roles. They generally monitor a broad range of operational activities in their area of responsibility and are responsible for monitoring a safe work environment.

Licensing, legislative and certification requirements that apply to this unit can vary between states, territories and industry sectors. Users must check requirements with relevant body before applying the unit.

Unit Sector

Coal mining (underground)

Assessment requirements

Modification History

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:

• implement inrush management plans on at least two occasions, including:

• identifying viable options and selecting the inrush management plan elements that best meet required outcomes
• conducting audits/enquiries/investigations and preparing reports.

During the above, the candidate must:

• locate and apply relevant legislation, documentation, policies and procedures and confirm work activity is compliant
• apply procedures and techniques for implementing inrush management plans, including:

• operating hand held monitoring equipment
• accessing and interpreting data from monitoring systems and equipment
• accessing and interpreting design criteria for inrush prevention and management systems and devices
• performing inrush planning mathematical calculations
• interpreting and applying mathematical and scientific theorems/laws related to inrush
• interpreting computer spreadsheets and inrush modelling/simulations
• accessing and interpreting archival and historical inrush information related to the mine

• work with others to implement the inrush management plan in a manner that meets required outcomes, including:

• communicating clearly and concisely with others to receive and clarify work instructions, and convey work progress
• identifying roles and responsibilities according to the inrush management plan
• identifying the relevant information and scope of the work necessary to meet required outcomes
• interpreting inrush training requirements.

Assessment Conditions

Mandatory conditions for assessment of this unit are stipulated below. The assessment must:

• include access to:

• inrush management plan

• be conducted in a safe environment; and,
• be assessed in the context of this sector's work environment; and,
• be assessed in compliance with relevant legislation/regulation and using policies, procedures and processes directly related to the industry sector for which it is being assessed; and,
• confirm consistent performance can be applied in a range of relevant workplace circumstances.

Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated work environment* provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessor requirements

Assessors must be able to clearly demonstrate current and relevant industry knowledge and experience to satisfy the mandatory regulatory standards as set out in the Standards for Registered Training Organisations (RTOs) 2015/Australian Quality Training Framework mandatory requirements for assessors current at the time of assessment and any relevant licensing and certification requirements. This includes:

• vocational competencies at least to the level being delivered and assessed
• current industry skills directly relevant to the training and assessment being provided
• current knowledge and skills in vocational training and learning that informs their training and assessment
• formal relevant qualifications in training and assessment
• having knowledge of and/or experience using the latest techniques and processes
• possessing the required level of RII training product knowledge
• having an understanding and knowledge of legislation and regulations relevant to the industry and to employment and workplaces
• demonstrating the performance evidence, and knowledge evidence outlined in this unit of competency, and
• the minimum years of current** work experience after competency has been obtained as specified below in an industry sector relevant to the outcomes of the unit.

It is also acceptable for the appropriately qualified assessor to work with an industry expert to conduct assessment together and for the industry expert to be involved in the assessment judgement. The industry expert must have current industry skills directly relevant to the training and assessment being provided. This means the industry subject matter expert must demonstrate skills and knowledge from the minimum years of current work experience after competency has been obtained as specified below, including time spent in roles related to the unit being assessed:

*Guidance on simulated environments has been stipulated in the Companion Volume Implementation Guide located on VETNet.

**Assessors can demonstrate current work experience through employment within industry in a role relevant to the outcomes of the unit; or, for external assessors this can be demonstrated through exposure to industry by conducting a minimum number of site assessments as determined by the relevant industry sector, across various locations.

*** While a unit of competency does not have an AQF level, where a unit is being delivered outside of a qualification the first numeric character in the unit code should be considered as the AQF indicator level for assessment purposes.
