Developing a Mechanised Cleaning System – for Cleaning Under and Around Moving Conveyors
2013
Follow on review of mechanised conveyor cleaning equipment close to being usable underground, flameproof and not, written to help the coal industry agree which options to develop.
What this report foundNo flameproof mechanised system for cleaning under and around moving conveyors was found to exist anywhere.
R1500,00
No flameproof mechanised system for cleaning under and around moving conveyors was found to exist anywhere. Of more than 200 mini machinery manufacturers identified worldwide, few build for mining, and only one or two products were near ready for surface use. Manufacturer interest in mining applications has since risen, but the industry has not settled on which technology to back.

A rating and ranking system was applied to South African coalfields and, separately, to the coal bearing countries elsewhere in the Southern African Development Community. The Waterberg ranked highest in South Africa and is the coalfield most worth detailed investigation as Witbank output declines. Botswana ranked highest among the other member states on contained resources and exploitation potential.
Recharge in Rehabilitated Opencast Collieries
2019
Groundwater levels and pumping records from five rehabilitated opencast pits at South African collieries, for hydrogeologists and closure planners estimating post-mining water balances.
What this report foundRecharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data.
R1500,00
Recharge factors of 23.5 per cent and 12.9 per cent were calculated at the two rehabilitated pits with complete data. The higher value reflected surface drainage towards the pit centre and eroded topsoil; the lower one, a deep pit floor with well compacted spoil and intact cover. The rates are site specific and no generic formula could be derived.
