Mining Risk Assessment

In coalfield areas the legacy of past mining activity represents a challenge to redevelopment and therefore the assessment of undermining risk is routine for this practice. Ordinarily, the risk assessment commences with an examination of a Coal Authority mining report as well as published geological data. This screens the need for more detailed assessment and mining risks are commonly ruled out at this stage.

For a number of sites mine abandonment plans might be consulted. The practice uses specialist scanning software to digitise and georeference mine abandonment plans so that they can be used as an overlay to site plans. On occasions, drilling into the workings is undertaken to further define risk and where this cannot be eliminated by relocation grout stabilisation is specified. Geotechnology has significant experience in the stabilisation of undermined areas.
