Elandspruit Colliery (in Mpumalanga, close to Middelburg).
Khanyisa Colliery (in Mpumalanga, west of Ogies, in close proximity to Kendal Power Station and sidings on the rail network)
Wescoal Processing Plant (in Mpumalanga, close to Middelburg and close to sidings on the rail network).
The Elandspruit Mine is located eight kilometers (“km”) west of the town Middelburg with location 25.80982°S latitude and 29.38474°E longitude. The site is approximately 200km from Johannesburg. It comprises of portions of the farm Elandspruit 291 JS. The Department of Water and Sanitation (DWS) awarded a WUL to Elandspruit in May 2015 allowing for development of the mine under all the necessary compliance requirements. As previously reported mining commenced during July 2015 and full planned production was achieved in October 2015. Since then, additional box-cuts were opened and the mine currently produces more than 210 000 tonnes from the opencast area.
The Khanyisa Complex comprises the previous Khanyisa mining area, the Catwalk and the Tri-Angle. The complex is located some 10km west of Ogies in Mpumalanga.
It comprises portions of the farm Heuvelfontein 215 IR. The location of the complex is 26.042950°S latitude and 28.973325°E longitude. The process of consolidation of the Khanyisa Mining Complex has been completed. The granted mining right is underpinned by a joint venture in respect of the Triangle area, the mining right to which has been incorporated with Khanyisa. A Water Use Licence (WUL) for the total integrated area was awarded 13 May 16.
The Khanyisa Complex was on care and maintenance for the majority of the FY17. The mining area had no production for the FY17 period but care and maintenance activities were focused on rehabilitating and preparing the area for full production to commence in the second quarter of 2017.
Vanggatfontein Colliery is 16km south-east of Delmas in Mpumalanga and supplies coal to Eskom and domestic industrial consumers. Last year the colliery sold 2 237 595t to Eskom and 98 252t to the domestic market.
Vanggatfontein reported a 0.23 LTIFR (FY16: 0.14). Zero harm remains a key focus with safety of paramount importance.
It had its IWUL issued by the DWS in January 2015. The colliery endeavours to be self-sufficient in terms of water supply and usage. Water from the opencast pits is pumped to the plant PCD which supplies the coal handling and processing plants before being recycled via slurry dams back to the PCD for reuse in the plant. Clean water for the operation of the flocculent plant is sourced from on-site boreholes. The water management system is designed to separate clean and dirty water, and to optimise the recycling and reuse of dirty water.
The total area of land disturbed is 356 hectares and the mine is not within nor adjacent to protected areas or areas of high biodiversity. Biodiversity management plans are therefore not considered necessary. Five bio-monitoring sites on the Wilge River and its tributaries are monitored during the wet and dry seasons. Blast vibration and noise monitoring are also conducted on a regular basis.
Fugitive dust at the Vanggatfontein Colliery is monitored at various locations to ensure compliance with applicable legislation. It has a weather station to assist in determining the sources of fugitive dust by correlating trend analysis with weather conditions. It also provides an early warning of large storms and high winds.
The quality of both ground and surface water is regularly monitored and the mine does not discharge any dirty water into the environment. Twenty-five boreholes are sampled on a monthly basis and test quality quarterly. Sixteen surface water sites are also sampled quarterly for quality.
Recycling of consumable waste has been limited to scrap metal and used oils. Processing waste is produced during the beneficiation of coal. Processing plant fine coal discard, or slurry, has for many years been stored in purpose-built Tailings Storage Facilities (TSFs) or co-disposal facilities. Slurry is used in the brickmaking industry and discard is used for briquettes in the domestic heating and industrial boiler industries.
