Batheaston Coal Company
Batheaston, near Bath
The 'Bath-Easton Coal Company' advertised a share issue to raise further funds in an effort to find and exploit coal. The advertisement included the following: 'Two 7-feet Shafts have been sunk, and completed with brick-work and timber, to the depth of 240 feet. A powerful Steam-Engine, made by Onions at Coalbrook-Dale, on Boulton and Watt's plan, with sixty-inch cylinder, furnished with two Boilers, and Pump-barrels of 15-inches diameter, is complete, and now at work. The mine being kept clear from water, the sinking will be resumed with the most flattering prospect of ultimate success, as soon as the Pump-barrels are properly secured. ......' [1]
The optimism was misplaced, and eventually, in 1813, the money ran out and the project was abandoned after boring to a depth of 671 ft. A concise summary may be found online [2]
