Proceedings of an International Symposium and Workshop on Borehole Geophysicsfor Mining and Geotechnical Applications, held in Toronto in August 1983. The contents include 41 papers and summaries of two afternoon workshops oninstrumentation and on interpretation and are arranged in order ofpresentation, in groups of papers on logging applications, calibrationaspects, EM methods, applied potential methods, acoustic methods, magneticborehold radar, magnetometric resistivity, gravity, x-ray and other nuclearmethods. The five papers from the earlier 1981 Geological Survey of CanadaMineral Logging Workshop concern inverse filtering of gamma ray logs, borehole IP, EM, resistivity and seismic measurements, and log calibrationand quality control.
"This manual describes recommended procedures for carrying out borehole logging, concentrating on practical aspects of the operation of interest to those actually involved in day-to-day field work."--Introduction.
Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact. The issue of possible contamination resulting from migration along boreholes, adits, shafts or tunnels unquestionably has been raised most forcefully with in the context of nuclear waste disposal. Several nuclear waste disposal programs, notably the Civilian and the Defence programs of the US De partment of Energy, the US Nuclear R...
