Overview on the application of geophysics in coal mining ...

30/07/2013  Over the past 40 years, coal mining geophysics has moved on from being a niche discipline developed to assist with the deep coal mines of Europe, to an activity applied around the world in a large range of mining and related situations. These include exploration for coal, mine planning, mine operations and environmental monitoring.
