Abstract
RECENT events in the mining industry point conclusively to the fact that its continued existence necessitates that old methods and old machinery should be ruthlessly scrapped, and that electric power should be used to a far greater extent than in the past. We are glad, therefore, that in this volume the more recent methods and modern specialised plant are adequately discussed. In the earlier chapters the usual academic discussion of generation and distribution is given. Later on, when describing the electrical gear requisite for any particular drive, full particulars are given of the peculiar characteristics of the drive. For example, the operating engineer must know whether it is a fan, a compressor, or a pump. Speed regulation is of great importance with certain drives, and the author rightly lays stress on this.
