Evidence of Knowledge
The candidate must demonstrate knowledge in installing underground in-seam directional drilling standpipes through:
accessing, interpreting and applying the organisation and site requirements and procedures for:
work, health and safety
environmental issues
operating drill rig
housekeeping
potential underground directional drilling hazards
the manufacturer’s requirements and procedures
the specific handling requirements for underground drilling equipment
basic geology types and their impact on underground in-seam directional drilling operations
drill bits for different geology types
reamers for different geology types
importance and functions of the standpipe
being prepared for fire/accident/emergency
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 in compliance with relevant legislation/regulation and using policies, procedures, processes and operational manuals directly related to the industry sector for which it is being assessed; and,
assessment may be conducted in conjunction with the assessment of other Units of Competency; and,
assessment must confirm consistent performance can be applied in a range of relevant workplace circumstances; and,
assessors must demonstrate the performance evidence, and knowledge evidence as outlined in this Unit of Competency, and through the minimum years of current* work experience specified below in an Industry sector relevant to the outcomes of the unit; or,
where the assessor does not meet experience requirements a co-assessment or partnership arrangement must exist between the qualified assessor and an Industry subject matter expert. The Industry subject matter expert should hold the unit being assessed (or an equivalent unit) and/or demonstrate equivalence of skills and knowledge at the unit level. An Industry technical expert must also demonstrate skills and knowledge from the minimum years of current work experience specified below in the Industry sector, including time spent in roles related to the unit being assessed; and,
assessor and Industry subject matter expert requirements differ depending on the Australian Qualifications Framework Level (AQF) of the qualification being assessed and/or Industry Sector as follows:
Industry sector | AQF** Level | Required assessor or Industry subject matter expert experience |
Drilling, Metalliferous Mining, Coal Mining, Extractive (Quarrying) and Civil Construction | 1 | 1 Year |
2 | 2 Years | |
Drilling, Coal Mining and Extractive (Quarrying) | 3-6 | 3 Years |
Metalliferous Mining and Civil Construction | 3-6 | 5 Years |
Other sectors | Where this Unit is being assessed outside of the Resources and Infrastructure Sectors assessor and/or Industry subject matter expert experience should be in-line with industry standards for the sector in which it is being assessed and where no Industry standard is specified should comply with any relevant regulation. | |
*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 frequent site assessments across various locations.
**Where a unit is being delivered outside of a Qualification the first numeric character in the Unit code should be considered to indicate the AQF level
