Unit of competency

Modification History

Application

This unit describes the skills and knowledge required to establish and maintain mining methods and strata management systems in underground coal mining, including design, development, audit and review processes and procedures.

It applies to those working in management roles. They generally perform complex, non-routine tasks involving strategic and planning activities and are responsible for establishing and maintaining operational systems and plans.

Licensing, legislative and certification requirements that apply to this unit can vary between states, territories and industry sectors. Users must check requirements with relevant body before applying the unit.

• accessing and evaluating data from monitoring systems and equipment
• performing mathematical calculations
• interpreting and applying mathematical and scientific theorems/laws related to mining structures
• accessing, interpreting and applying mine survey information
• interpreting and applying design criteria for mining structures systems and devices
• accessing and analysing historical strata information related to the mine and failure mode of mine structures

• work effectively with others to establish and maintain mining methods and strata management systems, including:

• communicating clearly and concisely with others to receive and clarify work instructions, and convey work progress
• identifying the relevant information and scope of the work necessary to meet required outcomes
• designing and establishing sequences for mining operations
• preparing technical procedures relating to mining structures.

Assessment Conditions

Mandatory conditions for assessment of this unit are stipulated below. The assessment must:

• include access to:

• strata management plan

• be conducted in a safe environment; and,
• be assessed in the context of this sector's work environment; and,
• be assessed in compliance with relevant legislation/regulation and using policies, procedures and processes directly related to the industry sector for which it is being assessed; and,
• confirm consistent performance can be applied in a range of relevant workplace circumstances.

Where personal safety or environmental damage are limiting factors, assessment may occur in a simulated work environment* provided it is realistic and sufficiently rigorous to cover all aspects of this sector’s workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.

Assessor requirements

Assessors must be able to clearly demonstrate current and relevant industry knowledge and experience to satisfy the mandatory regulatory standards as set out in the Standards for Registered Training Organisations (RTOs) 2015/Australian Quality Training Framework mandatory requirements for assessors current at the time of assessment and any relevant licensing and certification requirements. This includes:

• vocational competencies at least to the level being delivered and assessed
• current industry skills directly relevant to the training and assessment being provided
• current knowledge and skills in vocational training and learning that informs their training and assessment
• formal relevant qualifications in training and assessment
• having knowledge of and/or experience using the latest techniques and processes
• possessing the required level of RII training product knowledge
• having an understanding and knowledge of legislation and regulations relevant to the industry and to employment and workplaces
• demonstrating the performance evidence, and knowledge evidence outlined in this unit of competency, and
• the minimum years of current** work experience after competency has been obtained as specified below in an industry sector relevant to the outcomes of the unit.

It is also acceptable for the appropriately qualified assessor to work with an industry expert to conduct assessment together and for the industry expert to be involved in the assessment judgement. The industry expert must have current industry skills directly relevant to the training and assessment being provided. This means the industry subject matter expert must demonstrate skills and knowledge from the minimum years of current work experience after competency has been obtained as specified below, including time spent in roles related to the unit being assessed:

*Guidance on simulated environments has been stipulated in the Companion Volume Implementation Guide located on VETNet.

**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 a minimum number of site assessments as determined by the relevant industry sector, across various locations.

*** While a unit of competency does not have an AQF level, where a unit is being delivered outside of a qualification the first numeric character in the unit code should be considered as the AQF indicator level for assessment purposes.
