In case you missed it, Tim King of The Coal Authority posted on LinkedIn a really useful article on understanding a coal mining investigation. It includes information on workings, collapsing ground and effects on rock structure, and shows how important it is to interpret your GI data with care. It is useful reading for anyone working in coal mining areas. For more information, follow this link.
Based on our extensive experience in earthworks, we have recently completed a review of a draft earthworks specification for a confidential client. It involved looking at the planned site usage and the extent of the planned works to ensure the draft specification delivered an appropriate level of compaction without being too onerous or costly.
If you need any support on your earthworks projects then feel free to call our Dr Andy Goodwin to discuss how we could assist and add value.
We have recently been commissioned to assess the long term movements likely to occur due to settlement of old backfilled opencast workings at a site in Derbyshire. The aim is to support a proposal for adoption of an access road to a new development. The work is being undertaken as a sub-Consultant in a phased approach. Phase 1 of the project requires an initial mining records and geological appraisal. This will be followed in Phase 2 by the interpretation of skip loading tests on the fill and the appraisal of the likely impact of the predicted movements on the highway and its drainage.
