Blidworth Borehole

The Coal Authority invites you to tender for the drilling of a mine water monitoring borehole to assess rising mine water on the surrounding environment at Blidworth. A review of the mine water block by the Coal Authority in 2020 highlighted the potential for elevated mine water levels at Blidworth. 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 at Blidworth Colliery. The borehole is to allow monitoring of mine water levels that are thought to be representative of the area. The works required is detailed within the Scope and tenderers are advised to read and consider all aspects of the tender documents before preparing your tender submission.
