Pre-mining Surface Wells definition

Pre-mining Surface Wells means a well drilled into an unmined seam from the surface to drain methane from the seam and surrounding strata, often months or years in advance of mining. This is also known as surface pre-mining boreholes, surface-to-seam boreholes, and surface- drilled directional boreholes.
