New guidance for piling through coal issued

A new best practice guide published today by the Coal Authority is aiming to reduce the risk from encountering hazardous gases when drilling or piling through coal seams and former mine workings.

According to the Coal Authority, the need for the guidance has been highlighted by a number of serious incidents resulting from surface emissions of toxic gases into houses during the investigation and treatment of nearby former coal mine workings.

The Coal Authority joined forces with the Health and Safety Executive, British Drilling Association Federation of Piling Specialists, Association of Geotechnical and Geoenvironmental Specialists to develop the new best practice guide. The document gives guidance on the general procedures to be adopted when drilling or piling into former coal mine workings (including mine entries) and unworked coal, including how coal mine workings and unworked coal can be safely investigated and treated without the flush from drilling rigs displacing hazardous gases.

  • As a committed ornithologist, I trust the Coal Authorities advice on piling through coal, is not simply; "dangle a canary down the hole"
