Surface to in-seam directional drilling is a specialized technique used to intersect and verify the presence and extent of abandoned mine workings from the surface. By steering the drill bit along a planned trajectory that follows the orientation of the coal seam, operators can safely reach target voids without the need for underground access. This method allows for accurate confirmation of mine maps, detection of uncharted workings, and evaluation of potential hazards such as gas accumulations or subsidence risks, supporting mine safety planning and permitting processes.
