Geophysics at the Coal-Face: Exploration Geophysics: Vol ...

Abstract. Coal is a low-cost commodity and coal miners profit margins are slim, such that mining companies must maintain tight cost control to achieve acceptable returns. The challenge to coal geophysics is to adapt to these economic constraints and provide cost-effective, reliable methods for exploration and mining requirements.
