PEER REVIEW ROLE FOR DEVELOPMENT OF FORMER OPENCAST SITE

We have been working for several months now as a peer reviewer with a large developer to help with the preparation of an engineering solution for a complex site in the East Midlands. The site contains deep areas of uncompacted opencast backfill, which coupled with level, groundwater and fill variability issues presents significant challenges.  We have been involved with the review of potential solutions put forward by others, working collaboratively to constructively challenge ideas and assist in their development.  The work is continuing  and we look forward to being able to provide more details in the near future.

If you think we could assist you by providing a similar peer review service then please contact Dr Andy Goodwin on 01246 807808.

 

SETTLEMENT OF OPENCAST BACKFILL

Following successful delivery of a similar project, we were approached by a new client to support them on a large residential development in Derbyshire.  Since our appointment, we have completed the assessment of the likely settlement of backfill placed during previous coal extraction works and made movement predictions across the site both if the ground was not treated and if the ground was treated using vibro methods.  We are now about to aid the developer consider foundation solutions across the site, taking account of variable structural form, variable loadings and variable fill depths

SETTLEMENT OF OPENCAST BACKFILL

Over recent months we have been working with a developer on the assessment of the likely settlement of backfill placed during previous coal extraction works on a site in Derbyshire.  The assessment resulted in movement predictions across the site both if the ground was not treated and if the ground was treated using vibro methods.  The work showed that vibro techniques offered a potential cost-effective treatment solution and work is now progressing to develop the treatment design.

UNDERSTANDING A COAL MINING INVESTIGATION

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.

COAL EXTRACTION EARTHWORKS REVIEW

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.
