ELEMENT

PERFORMANCE CRITERIA

1. Excavate shaft

1.1. Access, interpret and apply compliance documentation relevant to the work activity

1.2. Inspect and evaluate site and ground conditions at the planned shaft location to determine the type of shaft to be sunk

1.3. Identify and address potential risks and hazards

1.4. Conduct or facilitate shaft excavation in planned location and type

1.5. Stabilise unconsolidated ground to prevent falls of ground and shaft collar erosion

1.6. Ensure shaft is supported by shaft pillar to ensure the integrity of the bottom section of the shaft

1.7. Secure area over shaft collar to prevent surface water inflow

1.8. Ensure that brow area near the bottom of the shaft, and the geology and walls, are visible for inspection

2. Fit out shaft

2.1. Fit access ladders securely in shaft in accordance with shaft conditions and code of practice

2.2. Install hoisting equipment at the surface of the shaft

2.3. Ensure that services supply devices to the shaft wall are fixed away from shaft conveyance equipment

2.4. Install shaft protection to prevent falls by people and animals, and unauthorised entry into the mine

2.5. Ensure that access shaft is free of unnecessary equipment and fixtures to allow unrestricted movement of materials

Required skills

Required knowledge

Specific knowledge is required to achieve the Performance Criteria of this unit, particularly for its application in the various circumstances in which this unit may be used. This includes knowledge of the following, as required to install underground shafts:

assessment of mine ground conditions

shaft location and types

shaft excavation methods and equipment

safety requirements for shaft excavation

legislative requirements for shaft excavation and use

services installed in mine shaft

fitting and locating services in shaft

shaft protection methods

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competency in this unit must be relevant to worksite operations and satisfy all of the requirements of the performance criteria, required skills and knowledge and the range statement of this unit and include evidence of the following:

knowledge of the requirements, procedures and instructions for installing underground shafts

implementation of requirements, procedures and techniques for the safe, effective and efficient completion of installing underground shafts

working with others to undertake and complete the installation of underground shafts that meets all of the required outcomes

consistent timely completion of underground shaft installation that safely, effectively and efficiently meets the required outcomes

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.

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

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.

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

consistent achievement of required outcomes

first hand testimonial evidence of the candidate's:

working with others to undertake and complete the installation of underground shafts

Guidance information for assessment

Consult the SkillsDMC User Guide for further information on assessment including access and equity issues.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Relevant compliance documentation may include:

legislative, organisational and site requirements, conditions and procedures

mine requirements

manufacturer's guidelines and specifications

Australian standards

Employment and workplace relations legislation
