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.
