ROTHS~IN, AJ KAUFMAN, R The a~proachlng maturity of deep ocean mining. The pace quickens. 1F,6T. MINING ENGINEERING, AD4E,VZ6, ~ , APR. 1974, P31-36. There are up to ten countries which are intereeted in deep ocean module mining at a time when unierstarzLi~g of the technologies, legalities ami msrkets is msturing; A few are ready now to move rapidly to commercial production. The mime sites, mining equipment, processing plants ~ markets are ~ Just informed extrapolations of yesterday's knowledge but are actual locations, designs, equipments, and produced metals.
ANONYMOUS Drivlm~ small-size t,,~r~is. 2F. AUSTRAL .MIN.%6, N3 ,MAR. 197~, P55" 56. A machine for drivlm~ - m ~ l u~ility tunnels tu~er populated areas was recently demonstrsted in S y ~ . This machine, the Mini Fullfacer, produced by Atlas Copco, consists of the tunnel-borir~ machine, with cut-~e~-head mounted on a swing housing and a power trailer with the operators cab. The operetion ar~ performance of this machine are described.

This paper describes a ~ w method of driving tunnels through ~razmlar soils above or belo~ the water table using a mechanical tunnelling machine within which the face is supported by a thixotropic slurry. The develol~ merit of the system and the results of the experimental tunnel drive at New Cross are reported. The methods of organizing azzl finamcir~ development work of this nature are discussed.

A system of stope development is proposed with the aim of improving ore recovery consistent with defined operating safety. It may be applied at ar~ stage of stope develol~nent stud provides for automatic collection of structural response data, comparison of observation with results of analysis using mathematical medals, and the prediction of response for the next stage of developmerit based on previously observed performance and c o p tinuously updated information.

US BUR.MI~S, IC 8624,197~,58P. The computer program HY~MODE, has been developed to meet %he need for a fast aud economical method for clusterir~ deta points on the s;here. The algorithm used in this devmlOlm~n% is an ~xtenalon of D. Wishar~'s onelevel mode analyses. The program can be used to cluster either vectorial or axial data and is currently being used by the Bureau of Mines to cluster fracture orientatlons.
