Work completed: 

• Project management 
• Procurement 
• Specialist personnel 
• Designed and installed steel soffits for both shafts to provide a foundation for demolition caps and enable future site use for gas production post mine closure 
• Constructed steel-reinforced concrete demolition caps to secure and seal shafts (over 900m deep) 
• Constructed a steel-reinforced concrete seal in the 5m² ventilation connecting tunnel (the ‘fan drift’) between the shaft and the mine ventilation fan. 

Completed work in an extremely challenging environment, ahead of schedule with zero accidents. 

Testimonial

Just a note to say thank you to your company (SES) and your team, for their assistance, professionalism & effort in completing the works at Harworth Colliery, both teams integrated & interacted excellently with our workers providing a cohesive professional team.

The whole project was completed without a single safety accident or issue, which is a credit to all concerned, would you please pass on my gratitude to all your staff for their commitment and effort, who made an extremely complex task look quite routine. I would certainly highly recommend the use of your company in any future works.

After 37 years in this industry, I never had the foresight to believe I would close Harworth Colliery, working with your team and achieving the excellent standards with regards to safety, workmanship and costs have made an extremely sad task, a very pleasing and rewarding experience.

Dave Lewis, Colliery Manager.
