Abstract
IN the USSR considerable technical improvements have been made in hydraulic methods of mining coal. In New Zealand coal mining by these methods is still comparatively crude. The Russian techniques are closely studied in New Zealand, and this description is based mainly on translations of technical articles. Fundamentally the methods in both countries are the same-chief developments in the USSR are the use of high pressure water jets, capable of winning all but the hardest coal without prior blasting, and hydraulic pipeline transportation where the gradient is unsuitable for flume transport.
