This is an infographic titled “Repairing and stabilising the mine shaft”. It explains how a mine shaft beneath a road will be repaired and stabilised, while also fixing damaged utility services and making the area safe for the future.
The infographic is organised into two main sections: a five-stage description of the work process and a cross-sectional diagram showing the underground structure.
Five stages of the work:
- Fill the shaft
Special grout is pumped into the mine shaft to fill voids and stabilise the ground. - Install a reinforced concrete slab
A strong concrete slab reinforced with steel is constructed over the shaft. - Add lightweight fill
Lightweight material is placed above the slab to provide support while reducing the weight pressing down on the structure. - Repair utilities and backfill
Damaged utility cables are repaired, and the excavation is carefully refilled. - Rebuild the road
The road surface is reinstated with new surfacing, drainage and road markings.
Cross-sectional diagram:
The diagram shows a vertical slice through the road and ground. At the top is the road surface, described as being reopened after the works. Beneath the road is an excavation approximately 6 metres deep. Within the excavation are telecom cables that require repair. Below the repaired services is a layer of lightweight fill material. Under this sits a reinforced concrete slab. Beneath the slab is a mine shaft approximately 50 metres deep and about 3 metres wide. The diagram is marked “not to scale”.
Benefits listed on the infographic:
- Safer for everyone.
- Protects underground services.
- Reduces future risk.
- Restores the road and keeps the area moving.
Summary:
The visual explains a five-stage engineering process to stabilise a deep mine shaft beneath a road. The shaft is filled and sealed, covered with a reinforced concrete slab and lightweight fill, utility services are repaired, and the road is rebuilt. The intended outcomes are improved safety, protection of underground infrastructure, reduced future risk and restoration of normal road use.
