All bore samples (up to 2015) are sent to Siza Coal Services Laboratory (SCS), a Middelburg-based SANAS-accredited testing laboratory with a full ISO/IEC 17025:2005 certification (last samples submitted in 2014). In addition, the proposed mining method, mining equipment and sample mass (chemical and physical analysis required) are also considered. REQUEST TO REMOVE Home [tmsgroup]get price. Wire-line logging results are only available for more recent boreholes. The depth to the top of no 2 seam depends largely on local surface topography and reaches a maximum depth of 80m along the eastern boundary of the mine lease area, and pinches and thins out in the eastern parts of the mining section due to local, pre-Karoo basement palaeo highs. Arnot and the applicable laboratory reviewed the Yanka round-robin system (to ensure that the laboratory's proficiency testing schemes are still in line with other independent laboratories on reproducibility and repeatability of results. website for supplementary Arnot mine produced thermal coal for over 40 years, using various mining methods, predominantly bord-and-pillar (currently mechanical), open-casting and short-walling between 1995 and 2005.

Universal Coal's large Arnot South project is to the south of Arnot and the in-closure Exxaro operation of Strathrae is adjacent to the east. All data collection (geological logging, description, interpretation, sampling, validation and capturing of drillhole cores information) is undertaken by qualified, trained and competent geologists on-site and aligned with Exxaro standards. Mapping captures intrusions, devolatilised coal, channel sandstones/in-seam partings, slumping structures, faults, joints, guttering, slabbing and floor rolls as well as measurements of mined heights, contamination and dilution. In addition, 1.5m core samples are taken every 20m to confirm the lithology in this regard. The mine produces around 5 million tonnes of coal per year.[1]. The Arnot coal mine is situated between the towns of Middelburg and Carolina in Mpumalanga, South Africa. Some 2 458 boreholes with applicable analysis were used for resource estimation, using the Minex growth algorithm.
