The Integrity of Continuous Miner and Personal Dust Samples
Coaltech | July 2021
R1500,00
Description
This project describes an extensive programme of ‘shadowing’ and monitoring of continuous miner and personal dust samples in production sections of an underground colliery over a three month period. One third of all respirable dust samples, both continuous miner and personal samples, have been shown to be unreliable. The main causes of unreliable samples were in the preparation, issuing, receiving, and wearing of dust pumps.

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.

No surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics rather than to technology, since the targets are small relative to their depth and conductive layers often lie above the seam. Borehole laser scanning remains the workable option, with sonar suited to flooded workings.
