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.

Westleigh Pumping Borehole

The Coal Authority (client) invites you to tender for the drilling of a mine water monitoring borehole to assess rising mine water on the surrounding environment at Westleigh, Wigan. A review of the mine water block by the Coal Authority has highlighted that mine water levels in the area could be elevated in respect to the rest of the block. There is potential for elevated mine water levels which could pose a risk to the overlying drinking water aquifers. Therefore, the Coal Authority requires construction of a borehole to intersect flooded underground workings at the former Priestner's Colliery at Westleigh, Wigan. The proposed borehole is to be used to improve understanding of mine water in the Golborne, Bickershaw and Parsonage mine water block and will be used for water level monitoring, water quality sampling and abstraction of water.
