MAGNETIC SURVEYING FOR BURIED MINE SHAFTS AND WELLS

The engineering implications of buried mine shafts and wells, and the methods of locating such features, are outlined. Indirect geophysical techniques are compared to direct investigation by drilling and trenching. Particular emphasis is placed on the magnetic surveying methods. Two examples of the use of magnetic techniques in apparently unfavourable environments, are detailed.(a) /TRRL/
