About DLM


DLM provides a Mining Consultancy service of the highest order, offering completely independent and professional advice tailored to meet our client's individual requirements.

Our services are based on over 40 years knowledge and experience in mining and mineral related matters, gained with National Coal Board/British Coal and in private practice, including the investigation of many subsidence events caused by belated settlement over shallow disused mine workings or abandoned mine shafts and adits.

Coal and Other Minerals

In mining areas it is imperative to demonstrate that the design and specification of new development provides satisfactory performance by taking due account of the possibility of workings below ground.

For a mining report to be comprehensive cognisance must be taken of extraction in all minerals, e.g. coal, oil shale, ironstone, limestone, sandstone, etc. The point is elementary but, in our experience, sometimes not fully appreciated.
