This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard will be useful to Rock Engineering personnel who are responsible to audit excavation stability.

People credited with this unit standard are able to:
  • Demonstrate knowledge of support principles.
  • Demonstrate understanding of the importance of support principles.
  • Demonstrate knowledge of the application of support principles.

    The skills, knowledge and understanding demonstrated within this unit standard are essential for social and economic transformation and contribute to the upliftment and economic growth of the mining and minerals sector.

    This unit standard is intended to promote general skills, knowledge and demonstrating a basic understanding of supporting principles in the mining and minerals sector in order to ensure knowledgeable and informed workers. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that learners are already competent in the following:
  • Outcomes related to National Introductory Certificate to Mining and Minerals (NQF Level 1).
  • Achieve mining excavation stability with support installation in the applicable geotechnical environment at NQF Level 1. 

  • UNIT STANDARD RANGE

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
