Evaluation of Ground Geophysical Techniques on the Waterberg Coal Fields
Interim account of trial ground surveys along a profile in the Waterberg coalfield, for exploration geologists weighing survey cost against the structural detail mine planning needs.
by C Combrink | February 2008
Electrical and electromagnetic ground surveys were run over a Waterberg profile with borehole logs and three dimensional seismic data as control, to test whether cheaper methods can match seismic reflection for locating coal and faults. Resistivity tomography at two electrode spacings, frequency and time domain electromagnetics, controlled source audio magnetotellurics and magnetics were all acquired. Results are preliminary.

Employee share ownership participation schemes are presented as a route to spreading mining wealth more widely after apartheid. They differ from profit sharing and pension arrangements in holding only the employer's own equity and in enlarging the company's capacity to borrow. Acceptance of such schemes in the South African mining industry was tested through an attitude survey of workers.
