and application of geophysical methods, as local coal mining companies generally do not have inhouse geophysicists. Consequently, the Coaltech Research Organisation''s Geology and Geophysics working group forum compiled a textbook aimed at addressing this need: to produce a guide for applying geophysics to coal mining problems in South Africa ...
Aug 18, 2015· Mining operations are complex. They aren''t your runofthemill type projects. These billion dollar complexes consist of various interconnected projects, operating simultaneously to deliver refined commodities like gold, silver, coal and iron ore. It''s a five stage process and we''ve broken it down using GIFs. Exploration
Longwall mining technique has been widely used around the globe due to its safe mining process. However, mining operations are suspended when various problems arise like collapse of roof falls, cracks and fractures propagation in the roof and complexity in roof strata behaviors. To overcome these colossal problems, an underground real time microseismic monitoring technique has been .

Mine voids in coal mines are usually encountered as resistivity lows because of the presence of acidic mine water. Other Methods, such as magnetics and ground penetrating radar have been used for detecting subsurface cavities, but can be subject to precision, interference, or depth limitations which restrict their use in mining applications.

The application of in seam seismic methods for coal seam exploration in connection with longwall mining is evaluated. The present exploration practice is reviewed. With the introduction of the relatively expensive high production longwall mining technique, in seam seismic methods are important to successful mining operations. The basics of relevant seismic methods are described, and a research ...
