Financial Benefits

The sale of extracted coal can often fund full remediation works. As well as bringing land back into use much earlier than originally planned.

In addition, costs related to abnormal foundation and contamination may be reduced – or indeed entirely removed. This also offers a more economical soluition than traditional methods.

Remediation

When remediation is required to remove any potential contamination from the land, Harland Resources can accommodate this work within the coal extraction process – thus reducing delays and potential additional costs.

Stabilisation

Abandoned underground mine workings can cause unstable ground – creating potential hazards to the public and property and often leading to increased foundations costs for developers.

If left untreated, extensive works will be required to mitigate the risk of potential collapse. ‘Prior extraction’ can offer a cost-effective solution to avoid this risk.

Reduced Gas Release

Abandoned mine workings can increase the risk of hazardous gases being present in sub-surface environments.

Mine shafts can be sealed during ‘prior extraction’ – releasing more surface area and making the site development plan easier to design.

The removal of shallow coal workings prior to development will also remove existing pathways for any source of hazardous gas.

Greater Certainty of Ground Conditions

‘Prior extraction,’ and the carefully monitored compaction of fill materials once the coal has been removed, creates an engineered fill to the developer’s final platform profile.

The works have been carried out to an engineering specification to NHBC and DOT specification 600 : Earthworks. This gives developers, local authorities and insurance companies confidence and peace of mind as to the quality of ground conditions.

Site specific requirements to suit particular construction requirements – such as high loads or low settlement tolerances – can usually be accommodated within the engineering specification of the works.
