Mine Workings

A complete step by step service

From very earliest times Man has exploited the Earth's valuable minerals by excavating or mining them. Included among these minerals are, most commonly, coal, fireclay, ironstone, sandstone, limestone and salt.  The result of this exploitation has been a legacy of abandoned mine workings, many at shallow depth, and mine shafts, whose precise location and status are, in many cases, unknown. These represent a major potential danger to existing and planned new structures.
