Required Skills
Required skills |
Specific skills are required to achieve the performance criteria in this unit, particularly for the application in the various circumstances in which this unit may be applied. This includes the ability to carry out the following as required to support underground shotfiring operations: apply legislative, organisation and site requirements and procedures apply personal and operational safety requirements access, interpret and apply technical and environmental information interpret geological and survey data apply procedures for drilling to patterns apply procedures for cleaning and testing holes apply explosives and detonators handling requirements and procedures identify potential hazards and manage risk apply record maintenance requirements use tools required to complete task apply environmental compliance requirements identify damaged/deteriorated explosives |
Required knowledge |
Specific knowledge is required to achieve the performance criteria of this unit, particularly its application in a variety of circumstances in which the unit may be used. This includes knowledge of the following as required to support underground shotfiring operations: site personnel and operational safety requirements legislative and site shotfiring requirements types and characteristics of explosives and protection measures associated with their use shotfiring techniques and procedures explosive handling, transportation and storage requirements shotfiring equipment characteristics, technical capabilities and limitations, site operational and maintenance procedures geological and survey data essential to shotfiring site environmental requirements and constraints related to shotfiring including blast monitoring systems physical and technical quality of explosives |
Evidence Required
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 supporting underground shotfiring operations implementation of requirements, procedures and techniques for the safe, effective and efficient supporting of underground shotfiring operations working with others to undertake and complete the underground shotfiring operations that meet all of the required outcomes consistent timely supporting of underground shotfiring operations 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. 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 requirement, procedures and techniques for the safe, effective and efficient achievement of required outcomes consistently achieving the required outcomes first hand testimonial evidence of the candidate's: working with others to undertake and complete underground shotfiring operations |
