Evidence Guide

Critical Aspects of Evidence

The evidence required to demonstrate this competency must be relevant to mine site operations. In addition to satisfying the requirements of all elements, performance criteria, required knowledge and skills, evidence must include demonstration of:

  • knowledge of all procedures, requirements and instructions to identify and rectify mine operating problems appropriate to a mine site; and
  • implementation of appropriate procedures and techniques for the efficient and effective identification and rectification of mine operating problems appropriate to a mine site, while complying with site risk control, health, safety, environmental, quality and communication requirements. This will include:
    • identifying operational processes, plant and equipment
    • monitoring plant performance
    • maintaining plant performance


Required Knowledge

Specific knowledge is required to achieve the performance criteria in this unit to the standards of performance required in the workplace, to transfer the skills to other contexts and to deal with unplanned events. Assessment requires evidence of the ability to identify and explain the purpose of:

  • operational safety procedures
  • operator responsibilities
  • plant layouts
  • operational procedures related to processes, plant and equipment carried out by the operator
  • mine communication procedures and systems
  • process, plant and equipment type purpose, application, characteristics and limitations
  • process, plant and equipment monitoring systems, programs and interpretation
  • plant and equipment maintenance systems and procedures
  • emergency shut-down procedures
  • environmental requirements and controls related to processes, plant and equipment
  • health and safety requirements and controls related to processes, plant and equipment


Required Skills

Specific skills are required to achieve the performance criteria in this unit. Assessment needs to obtain evidence of the ability to:

  • access, interpret and apply technical and safety information
  • operate plant and machinery
  • communicate and coordinate activities with others
  • maintain plant and equipment records
  • apply diagnostic/fault finding techniques
  • use hand and power tools
  • comply with environmental requirements


Assessment and Interdependence of Units

This unit may be assessed with other relevant units forming a cohesive work function, according to specific mine site requirements.


Resource Implications

Assessment of this competency requires typical resources normally used in a mine site work environment. Selection and use of resources for particular sites may differ due to site conditions, equipment availability, equipment/plant types and different contexts.


Consistency in Performance

To ensure consistency of performance, this unit may be assessed over a period of time and a range of work and site conditions. Local site factors will influence the breadth of evidence required to demonstrate the competency.


Context for Assessment

This unit should be assessed in the work environment where possible. Some assessment events may be conducted under simulated conditions where issues of safety and environmental damage are limiting factors.

All assessments must be valid, reliable, fair and flexible accumulating sufficient evidence to demonstrate the required competence. The assessment environment should not disadvantage the participant. For example, language, literacy and numeracy demands of assessment should not be greater than those required on the job.


Methods of Assessment

Appropriate methods of assessment for this unit will usually include:

  • workplace observation of processes and procedures
  • oral and/or written questioning on required knowledge
  • testimony from supervisors, colleagues, clients and/or other appropriate persons
  • simulation and/or scenario analysis

Where performance is not directly observed and/or is required to be demonstrated over a period of time and/or in a number of locations, any evidence should be authenticated by colleagues, supervisors, clients or other appropriate persons.

Questioning should be undertaken in a manner appropriate to the language and literacy levels of the candidate and to the requirements of the unit of competency.
