At its inception, the Coire Glas Exploratory Works was a short project, but by no means unambitious, to undertake detailed ground investigation in an area where normal methods simply wouldn’t work.

Owing to the vast underground structures planned for the wider Coire Glas Pumped Storage scheme, and the mountainous terrain above, a bold package of GI was put together to de-risk the future works. This included a significant campaign of surface drilling, in difficult to access locations (completed by Fugro), and the construction of a 900m Exploratory Adit, accessing deep under the mountain.

This lecture will run through the full story of the construction of the Exploratory Adit, which proved to be very much as its namesake; exploration. With a large fault zone encountered at over 700m in, and an extension to the tunnel length for a broader scope of exploratory drilling and in-situ geological testing, the project was filled with interest.

Note: For in-person attendance, advance booking is not required; please register on arrival. To attend online, kindly use the ‘Book now’ button.

Following the lecture, there will be a networking session with food and drinks in the ICE Kendal's bar, sponsored by Strabag.

Joe Coxson

Between studying Mining Engineering in Cornwall, and joining the Coire Glas project in the Highlands of Scotland, Joe has worked underground across the full length of the UK.

His 10 years in the industry have been wide ranging, including SCL tunnelling at Whitechapel and Liverpool Street Stations for Crossrail, and TBM experience on the cooling water tunnels for Hinkley Point C and the MTS Drive for the Woodsmith Project.

Those who know Joe will understand Coire Glas was an obvious dream project, as not only is he enthusiastic about drill and blast works, but when he’s not underneath the mountains, he’s often found clinging onto the side of them by his fingertips or ice axes.
