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.

The Relationship Between Geological Structures and Dolerite Intrusions in the Witbank Highveld Coalfield, South Africa
2008
Structural study of dolerite dykes and sills at four collieries south of the Ogies Dyke, linking intrusion geometry to mining conditions and coal quality. For mine geologists.
What this report foundDolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield.

Dolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield. In decreasing order of importance, intrusions cut safety by raising the risk of roof, pillar and floor failure, raise mining costs, reduce saleable tonnage, and increase waste generation and environmental risk.
