Presents a case history of the sir~iug of a ventilation shaft at John Darling colliery through saturated sands in Belmont Lagoon, near Newcastle, Australia. Ground freezirg was used to form a circular ice wall to support the excavation until it was subsequently lined with reinforced concrete. 824181 MODEL TANK TEST USING ARTIFICIAL GROUND FREEZING WITH AN IN-GROUND I~G STORAGE TANK IN VIEW Akiyama, T; Iglxro, M Engrg Geol, VI8, N1-4, Dee 1981, P395-408 (Paper to 2nd International Symposi~n on Ground Freezing, Trorzlheim, 24-26 June 1980) Describes a model tank test carried out as part of a feasibility stt~dy for a large scale Liquefied Natural Gas (LNG) storage tack. The surrounding ground around the test tark was frozen to a lOm diameter and TOm depth. A shaft was then sark 26m below ground level for various tests and measlK~ements. 824182 FREEZING IN VERTICAL SHAFT SINKING (IN RUSSIAN) Voloshchuk, S N Shakhtnoe Stroit, ES, Aug 1981, P24-27 Describes laboratc~y and field work on the placement ~f freeze holes for a shaft to be driven through weak, friable, waterlogged rock. 824183 ROCK FREEZING RATEs (IN RUSSIAN) Shparber, P A Shakhtnoe Stroit, N7, July 1981, P23-24 Thermal conductivity, freezing temperatures, freeze-coltmm spacing and arramgement~ anl possible infiltration paths are the main factors affecting rock freezing rates. C ~ e s should be latoratc~y tested to determine the thermal conductivity around each separate freeze col~nn. 824184 D~EP-LEVEL FREEZING (IN RUSSIAN) Shpsrber, P A Shskhtnoe Stroit, NS, May 1981, P8-11 Freezing I~ocedures used to freeze to a depth of 620m (a maxinm~n in the USSR) are described.

Presents a case history of the geological investigations carried out to assess the feasibility of Nitzanlm as a nuclear power plant site. Problems encountered included irregularly-cemented kurkar sand formations which were difficult to sample and ar~lyee, nearby allegedly active faults, and many other proposed faults. All the proposed faults were shown to be non-existent or irrelevant to feasibility. 824189 EVALUATION OF POTE~flAL SOURCES OF RIPRAP AND A ~ M O R S T O N E - METHODS AND CONSIDERATIONS Lie~hart, D A; Stranaky, T E Bull Asmoc Ergng Geol, V18, NB, Aug 1981,
