Subsidence map development in an area of abandoned salt mines
Morphological mapping is not generally associated with mining and subsidence, having traditionally been used to define the nature and extent of surface features such as landslides and landforms. However, detailed morphological mapping, linked to subsurface investigation, can provide a preliminary indication of potential subsidence hazards in some areas of abandoned mine workings. This example describes how mapping was carried out in an undeveloped part of the Cheshire saltfield, prior to any subsurface investigation, with the aim of establishing the likely extent to which a number of mines had collapsed.

This volume presents a collection of papers on techniques and case studies in land surface evaluation for engineering practice written by specialist practitioners in the field. The volume arose out of deliberations by the Second Working Party on Land Surface Evaluation set up by the Engineering Group of the Geological Society in January 1997 and chaired by Dr. J. S. Griffiths. The book examples of cost-effective methods for collecting land surface and near surface data prior to carrying further detailed ground investigations of engineering geologist, geotechnical engineers, geomorphologist and planners who have the responsibility for planning a designing investigations of potential sites of development.
