working with others to establish and maintain ground control and stable mining systems in underground metalliferous mines

consistent and timely establishing and maintenance of ground control and stable mining systems in underground metalliferous mines

Context of and specific resources for assessment

This unit must be assessed in the context of the work environment. Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated environment provided it is realistic and sufficiently rigorous to cover all aspects of workplace performance, including task skills, task management skills, contingency management skills and job role environment skills.

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.

Customisation of assessment and delivery environment to sensitively accommodate cultural diversity.

Aboriginal people and other people from a non English speaking background may have second language issues.

Assessment of this competency requires typical resources normally used in the work environment. Selection and use of resources for particular worksites may differ due to site circumstances.

Where applicable, physical resources should include equipment modified for people with disabilities.

Access must be provided to appropriate learning and/or assessment support when required.

Method of assessment

This unit may be assessed in a holistic way with other units of competency. The assessment strategy for this unit must verify required knowledge and skill and practical application using more than one of the following assessment methods:

written and/or oral assessment of the candidate's required knowledge

observed, documented and/or first hand testimonial evidence of the candidate's:

implementation of appropriate procedures and techniques for the safe, effective and efficient achievement of the required outcomes

identification of the relevant information and scope of the work required

identification of viable options and the selection of systems that best meet the required outcomes

consistently achieving the required outcomes

first hand testimonial and documentary evidence of the candidate's:

working with others to establish and maintain ground control and stable mining systems in underground metalliferous mines

consistent and timely gaining of approval of ground control and stable mining systems in underground metalliferous mines

provision of clear, timely required support and advice on the implementation of ground control and stable mining systems in underground metalliferous mines
