|PURPOSE AND RATIONALE OF THE QUALIFICATION|
The purpose of this qualification is to equip learners with the theoretical knowledge, technical skills and practical ability to function as a Junior Strata Control Officer within the mining environment. Junior Strata Control Officers assist personnel engaged in mining operations to ensure:
Seen on a national level, safe and productive mines operate at optimal level; with maximum orebody extraction, the lowest possible safety risk and best operating cost. This has spin-off benefits in terms of the sustained production of minerals, with increased generation of revenue for the economy, greater investment in South African mines by particularly overseas investors and sustainable employment opportunities within the mining industry for society in general.
This qualification will equip the learner with necessary knowledge, skills and ability for promotion to the post of Junior Strata Control Officer. It is also intended to provide the building blocks upon which to build a further career in rock engineering. Attaining this qualification will improve the learner's skills, thus increasing his potential employability. The concept of the four different streams, with appropriate elective unit standards, means that the learner can move between the different mining operations areas by completing the necessary elective unit standards.
Learners credited with this qualification will be able to:
On a practical level, learners equipped with this qualification will be able to conduct the essential operations associated with:
Strata Control forms part of the discipline of Rock Engineering, one of the specialist disciplines within the mining environment. Rock engineering may be defined as technical mine engineering that bridges the gap between mining geology and production engineering. Its application turns geological and geotechnical information into rational mine plans, that facilitate maximum orebody extraction at least safety risk and lowest operating cost for the prevailing rockmass conditions. Rock engineering is concerned with the design of mining strategies, excavation layouts and support systems that ensure safe, stable and productive mining operations. There is a need for this qualification as there is a shortage of skilled Rock Engineers as identified in the Sector Skills Plan. This qualification is also necessary as the skills level amongst mining personnel has declined to such an extent that they can no longer conduct Strata Control operations as part of their day-to-day operations.
Strata Control may be defined as a risk management tool, which in part ensures the proper control of the mining environment to minimise the risk of local instability. Effective strata control ensures that on a local scale, appropriate mining strategies and/or support actions are employed to overcome local and unforeseen or unpredictable changes to the prevailing geotechnical environment. This requires on-site training in the mechanics of, and reasons for, excavation failure and the roles and mechanisms of excavation support.
The role of strata control also extends to ensuring adherence to mining layout and support standards, as well as the maintenance of quality control in support type selection and support installation. This is emphasised because the value of even the best available rock engineering advice is diminished if recommended standards and systems are not properly understood or implemented underground.
This NQF Level 3 Qualification builds on the basic foundation of theoretical knowledge, technical skills and practical ability applicable to the discipline of strata control and rock engineering provided by the NQF Level 2 Qualification. The NQF Level 3 Qualification develops the learner's focus from merely "recording" strata control-related issues towards recognizing, investigating and interpreting these issues. It is intended to assist Strata Control Observers to further their career in rock engineering, as well as serve as the appropriate qualification for a learner to be appointed as a Junior Strata Control Officer. This Qualification has 4 specialisation streams for learners to follow, based on different mining environments which vary significantly in geological composition, geotechnical environment and extraction method.
Learners entering this Qualification will typically be Strata Control Observers working in a rock engineering department or consultancy, with a NQF Level 2 National Certificate in Strata Control or similar, although learners with other relevant NQF Level 3 Qualifications wishing to articulate horizontally will also be considered. While completing the qualification, learners will ideally act or relieve in the position of Strata Control Officer or Junior Strata Control Officer as part of their experiential learning.
Upon obtaining the qualification, the learner will be eligible for appointment as a Junior Strata Control Officer. As such, he/she will be responsible for strata control-related issues for a small shaft or mine, or a section of a larger mine, either alone or with the assistance of one or more Strata Control Observers whom he/she will be expected to supervise.
This is the third qualification in a learning pathway for Rock Engineering. A typical learning pathway for learners with this qualification within the rock engineering discipline begins with the GETC: Mining and Mineral Processes (entrance into discipline), National Certificate: Strata Control Operations NQF Level 2, National Certificate: Strata Control Operations NQF Level 3 and ends with the FETC: Strata Control Operations NQF Level 4. The series provides a developmental pathway for the full range of activities required for Strata Control.

Integrated assessment at the level of the qualification provides an opportunity for learners to show they are able to integrate concepts, actions and ideas achieved across a range of unit standards and contexts.
Integrated assessment must evaluate the quality of observable performance as well as the thinking behind the performance, and must be based on a summative assessment guide. The guide will spell out how the assessor will assess different aspects of the performance and will include:
In some cases inference will be necessary to determine competence depending on the nature and context within which performance takes place.
It is necessary to ensure that the fundamental part of the qualification is also targeted to ensure that while the competence may have been achieved in a particular context, learners are able to apply it in a range of other contexts and for further learning. The assessment should also ensure that all the critical cross-field outcomes have been achieved.
The learner may choose in which language s/he wants to be assessed. This should be established as part of a process of preparing the learner for assessment and familiarising the learner with the approach being taken.
While this is primarily a workplace-based qualification, evidence from other areas of endeavour may be introduced if pertinent to any of the exit-level outcomes. The assessment process should cover both the explicit tasks required for the qualification as well as the understanding of the concepts and principles that underpin the activities associated with the strata control.
|The following strategy was followed when research was conducted into international qualifications which could be used to inform the structure of this qualification:
This is based on an informative summary of world mining regions was found on the website www.mbendi.co.za.
North America is the major producer of gold and silver. Raw mineral production in 1998 was valued at approximately US$ 70 billion. The industry employs approximately 1 million people. Major companies include Barrick, Newmont and Industrias Penoles.
Europe is not a major mining centre. However, it has several established base metal mines in Scandanavia, Ireland and the Iberian Peninsula. Major companies include Boliden and Outokumpu.
Asia is a major producer of base metals, PGE's, ferrous metals and coal. Most major producers are state controlled, but foreign investment is being encouraged, in particular by China, India and the CIS.
South America is a major producer of base and ferrous metals, in particular copper and iron ore. Major companies include Codelco, Barrick, CVRD, Newmont and Rio Tinto.
Africa is a major producer of cobalt, gold, PGE's and diamonds. Mining accounts for a substantial proportion of several countries GDP's. Major companies include Anglo American, De Beers and BHP Billiton.
Australasia is a leading producer of iron ore, gold and base metals. Major companies include BHP Billiton and Rio Tinto.
The Southern African mining industry finds itself in a unique situation, in that most mining operations are very labour-intensive, with the workforce generally having a low standard of education. Comparable operations in overseas countries such as the United States, Canada and Australia are highly mechanized, with well-qualified operators. In line with this approach, overseas mines do not have rock engineering departments-strata control issues are handled by the production personnel, while higher-level rock engineering is contracted to specialist consultancies. For this reason, international comparability for Strata Control qualifications from Levels 2 to 4 is extremely difficult. While there may well be study material available for these levels, it is intended for use by production employees and is not of a specialist nature.
Frameworks consulted were those of Australia, New Zealand, United Kingdom (Britain) and Scotland.
While conducting the research in this regard, no evidence could be found of a strata control qualification per se comparable to NQF Level 3.
A number of unit standards (competencies) were found on the New Zealand Framework. Web address: www.nzqa.gov.nz: packaged in the qualification MNC30304: Certificate III in Underground Coal Operations:
There were also units at Technical Management level (not related to a qualification):
The United States and Canada are considered leaders in the world in terms of mining methodology, equipment and training:
> Using Mines Safety and Health Administration (MSHA) statistics and extensive interactions with the mining community to identify the most critical hazards.
> Employing state-of-the-art strata control science in a targeted program of research that develops practical solutions.
> Aggressively transferring research results to end users in the mining community.
> Serving as the mining community's resource for the best strata control information available, and providing training and technical assistance consistent with this mission.
In the SADC region officers within the rock engineering supportive services area in mines are taught the skills at the workplace. No generic courses/programmes could be found to perform a comparative analysis.
International comparability in this instance has not revealed comparable qualifications for one or more of the following reasons:
The competencies covered by the National Certificate Strata Control (Level 3) are needed by the mining industry and it is highly motivated that learners should learn towards and be assessed against the relevant standards.
Despite lack of any internationally comparable qualifications, it is nevertheless deemed a valuable and relevant qualification.
|This Qualification allows for both vertical and horizontal articulation.
Vertical articulation exists with:
Horizontal articulation can occur between the various strata control specialisation areas, and on a unit standard level within the different NQF Level 3 qualifications, such as:
