Mining in Southwest England has been carried out from very early times. Most of the mining was for metalliferous ore (copper, tin, arsenic, lead etc.) contained in narrow veins (lodes) in the bedrock. Non-metalliferous deposits including coal, lignite, ball clay, slate and free-stone were also mined. The majority of mining activity had ceased by the early twentieth century but the legacy of the mines lives on with concealed hazards such as poorly capped mine shafts, shallow mine workings and contaminated land.
We have an in depth knowledge of historical mining in Devon and Cornwall and have at our disposal an extensive in-house archive of mine plans, historical maps and technical reports. We also have a continuing programme of research at Record Offices and Local Studies Libraries.
The investigation of old mine sites is carried out in several stages. Initially a Mining Desk Study is prepared to establish the extent of recorded mine workings. Insitu Mining Investigations are then targeted at the recorded and suspected mine workings and the results used to design and implement appropriate Remedial Engineering Safety Works, as deemed necessary.
