Purpose
People credited with this unit standard are able to demonstrate
knowledge of the effects of geological features on surface
extraction methods, and demonstrate knowledge of surface
extraction methods to produce end product in relation to
geological conditions at extractive sites.

Outcomes and evidence requirements
Outcome 1
Demonstrate knowledge of the effects of geological features on surface extraction
methods.
Evidence requirements
1.1
The effects of geological features at a surface extraction site are described in
relation to extraction methods required to extract the economic material.
Range
1.2
The geological features and physical characteristics of rock material at a
surface extraction site are described in terms of their effect on fragmentation.
Range
1.3
includes but is not limited to – faults, folds, joints, bedding planes,
washouts, dykes, sills, weak and/or crush zones.
includes but is not limited to – strength, bedding, jointing, bulking,
fabric.
Potential extraction methods are evaluated in relation to geological features and
fragmentation.
Range
may include but is not limited to – drill and blast, digging, loading,
scraping, dozing, ripping, crushing, screening, haulage, working
surfaces.

Outcome 2
Demonstrate knowledge of surface extraction methods to produce end product in relation
to geological conditions at extractive sites.
Evidence requirements
2.1
The effectiveness of different extraction methods is evaluated in relation to their
ability to mine or quarry and load the material.
Range
2.2
The effect of processing methods is evaluated in relation to the ability of the
mined or quarried material to fulfil its end-product use.
Range
2.3
may include but is not limited to – discharge, stockpiling, reclaim,
screening, washing, crushing, dilution, product quality, product
deterioration, contamination.
The effect of extraction methods is evaluated in relation to effect on geography
and topography.
Range
2.4
includes but is not limited to – drill/blast, front-end loaders,
hydraulic excavators, hydraulic and electric shovels, motor
scrapers, draglines, bulldozers, bucket wheel excavators, suction
and bucket wheel dredges.
may include but is not limited to – dump heights, contouring, water
management, diversions, rehabilitation, bunds, visual screening,
re-vegetation, slope stability.
The geology and surface features of a site are explained in terms of the design
and layout of the site.
Range
Planned review date
may include but is not limited to – flat site, gradient of site,
benching, rock faces, slope stability, ponding, underwater
excavations, location, site features, face height and slope, slope
stability, water effects, underwater excavations, old workings.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
