Potentially hazardous mine workings (as identified from the desk study and insitu investigation) should be properly secured to mitigate any future risks from ground subsidence.
In areas of new development, mine shafts and lode outcrop workings are often permanently plugged or capped with reinforced concrete to modern design standards. In less sensitive areas the use of fences, metal cages and grilles are frequently used to prevent entry.
We are able to provide geotechnical advice on suitable means of securing the mine workings. We are also able to provide advice on how to deal with areas of Contaminated Land that might be present on the site.
