This unit describes a participant’s skills and knowledge required to implement the inrush management plan in Coal mining.

This unit is appropriate for those working in supervisory roles.

Licensing, legislative, regulatory and certification requirements that apply to this unit can vary between states, territories, and Industry sectors. Relevant information must be sourced prior to application of the unit.

Evidence is required to be collected that demonstrates a candidate’s competency in this unit. Evidence must be relevant to the roles within this sector’s work operations and satisfy all of the requirements of the performance criteria of this unit and include evidence that the candidate:

locates and applies relevant legislation, documentation, policies and procedures

implements the procedures and techniques for the safe, effective and efficient implementation of the inrush management plan including:

operating hand held monitoring equipment

accessing and interpreting data from monitoring systems and equipment

accessing and interpreting design criteria for inrush prevention and management systems and devices

performing inrush planning mathematical calculations

interpreting and applying mathematical and scientific theorems / laws related to inrush

interpreting computer spreadsheets and inrush modeling/ simulations

accessing and interpreting archival and historical inrush information related to the mine

works with others to undertake and complete the implementation of the inrush management plan that meets all of the required outcomes including:

communicating clearly and concisely with others to receive and clarify work instructions, and convey work progress

identifying roles and responsibilities in accordance with the inrush management plan

identifying the relevant information and scope of the work necessary to meet the required outcomes

interpreting inrush training requirements

demonstrates completion of implementing the inrush management plan that safely, effectively and efficiently meets all of the required outcomes on more than one (1) occasion including:

identifying viable options and selecting the inrush management plan elements that best meet the required outcomes

conducting audits/enquiries/investigations and preparing reports

The candidate must demonstrate knowledge of implementing inrush management plans through:

systems of mining including:

tunnels, drifts, stone drivage, shaft sinking, pillar extraction, partial extraction, punch mining and fault drivage

factors affecting stability of mining structures including:

stress analysis: including mining induced stress and topography

sedimentology: including subsidence, water bearing strata, permeability of seam and strata, hydrology, hydrogeology, physical property testing, caving characteristics, outburst, over and underlying strata

mining structure failure modes

systems of work including:

bord and pillar, place changing, longwall, highwall, auger mining, pillar extraction, partial extraction and punch mining

identifying and applying mining and general engineering principles relevant to the behaviour of excavations in rock and coal including:

audit methodologies

mine mapping of inrush zones, related geology and features

differing geological features and conditions on inrush zones including:

the effects of coal seam characteristics on inrush

faults, dykes, intrusions and strata deformities

monitoring systems and techniques including:

fixed monitoring systems: types, uses/limitations, design criteria, specifications and design processes

portable monitoring equipment: types, uses/limitations

the use of simulation techniques and applications relevant to inrush

use of computer-based systems for real time monitoring

methods of control of inrush

types of inrush control zones

processes and techniques for determining alarms and trigger points/levels

emergency response and evacuation/disaster planning processes and techniques

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:

*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

Foundation skills essential to performance are explicit in the performance criteria of this unit. Further information is available in the Resources and Infrastructure Industry Training Package Companion Volume.
