Site investigation and field observation 1860 BELL, FG Site investigations in areas of mining subsidence. Textbook. Figs,Tabls,Ref s. N EWNES_ BUT~TWORTHS, LONDON, 1975,168P. This text outlines how site investigations may be carried out and reviews mining methods. It also makes some suggestions concerning the methods by which foundation problems caused by mining operations, either past or present, may be dealt with. There are eight chapters, as follows: Introduction, by F.G.Bell; The character of the Coal Measures, by F.G.BelI; Field investigation techniques, by J.C.Dixon; Geophysical methods in site investigations in areas of mining subsidence, by A.N.Burton; Improved geophysical techniques for survey of disturbed ground, by M.Howell and C.W.Amos; Mining s~bsidence, by C.H.Shad. bolt; Characteristics of shallow coal-mi~e workings and their implications in urban redevelopment areas, by R.K.Taylor; and Foundations on the coal measures, by J .L.Knill. 1861 DD(ON, JC SOIL MECH. LTD. BRACKNELL, GB Field investigation techniques. In Site investigations in areas of mining subsidence. 18F,hT,20R. NEWNES -BU~E~TWORTHS, LONDON, 1975, P40- 74. This paper sets out the current field procedures in subsurface exploration in the widest sense and includes methods of exploring below the ground surface by direct, semi-dlrect and indirect means, the various types of sample which can be obtained and the range of In-situ tests which may be carried out. 1862 PODIo,AL YANG, JH GRAY, KE Early warnlr~ system of impendillg rock failure for safety in mines and excavations.Report.47F .

In Site investigations in areas of mining subsidence. 6F. NEWNES.BUTI~WORTHS, LONDON, 1975, P103-108. Two new techniques have been developed which appear to provide improved geophysical methods for locating a variety of sub-surface features, particularly old mine workings, filled quarries, cavities, faults, culverts and similar phenomena. These methods, described in this article, are current-path electroms4~etic prospection and seismic reflection.
