Mining remediation work helps bring new line one step closer

As the main works get underway at the northern end of the Borders Railway, mining remediation works at Eskbank and Newtongrange have begun to prepare other locations along the route for the arrival of the railway.

The work involves stabilising the ground where the railway crosses old mine works. Drilling rigs have been brought onto the two sites to identify the location of underground voids, while a pumping rig is used to fill any cavities.

Mining remediation along the route began in earnest last November in the old Monktonhall colliery area. Since then, over 4,000 tonnes of grout has been pumped into old mines, and over 300km of drilling has taken place.

Ahead of the latest mining remediation works, Network Rail and BAM have been liaising with the local community through letter drops, while at Eskbank the team has been talking regularly with Edinburgh College to ensure minimum disruption to students and staff.

Hugh Wark, Project Director, Network Rail said: “Mining remediation works are essential to ensure that we have stable ground ahead of construction of the railway tracks. So far, we have carried out extensive work in the Monktonhall area and, as site investigations are on-going along the route, Eskbank and Newtongrange have been identified as locations requiring work.

“As with all construction activity throughout the project, it is important to us that the local community is kept informed.

“We have carried out a substantial letter drop across both areas, and have also held meetings with representatives at Edinburgh College to ensure they know what the works will mean for staff and student access to the college.”

The works at Eskbank and Newtongrange will continue over the coming four to six weeks.
