Klipspruit colliery is experiencing coal losses which has a negative impact on coal production and subsequently loss in revenue. This study aimed to identify the possible causes of coal losses in the four seam. The objectives of the study was to identify potential sources of coal losses through a literature survey, to identify sources where the coal losses occurred, to determine factors affecting coal losses and to identify the most cost-effective methods to reduce coal losses.
It was determined that highwall losses, top of coal losses and coal edge losses were the major areas of coal losses experienced at Klipspruit Colliery. These losses were mostly attributed to the drilling and blasting practises of the pre-split, interburden waste and the coal seam.
Recommendations include re-visiting the current pre-split design and the tolerances adopted for the interburden and coal seam drilling and blasting design. It is furthermore recommended for Klipspruit Colliery to implement a continuous improvement plan for the drilling and blasting practises and refresher training for the blasting crew and operators.Downloads
