Description

The Coal Authority invites you to tender for the drilling of a mine water monitoring borehole(s) to assess rising mine water on the surrounding environment at sites at Thornley and Deaf Hill. A review of the mine water block by the Coal Authority in 2020 highlighted the potential for elevated mine water levels at Thornely & Deaf Hill sites. Elevated mine water levels could pose a risk to the drinking water aquifers that overlie the mine workings. Therefore, the Coal Authority intend to construct a borehole to intersect flooded underground workings. The borehole is to allow monitoring of mine water levels that are thought to be representative of the area.
