This book is virtually an encyclopedia of coal-mining. The geology of the coal-measures, the composition and analysis of coal, trial borings and shaft-sinking, blasting, coal-cutting, methods of working, timbering, haulage, winding, pumping, ventilation, transmission of power, mine-surveying, lighting, explosions, mineral leases, preparation of coal for market, the economics of coal, and relief and exploratory work in case of accidents - such is the wide range of its subject-matter.

Practical Coal-mining is thus a practical work for all concerned in coal-mining.

The book is profusely illustrated with diagrams. Machinery, structures, implements, details of all kinds are carefully pictured. There are also some excellent coloured drawings and black-and-white plates of interesting scenes and details connected with coal and coal-working in some of its phases. The plates include maps of the great British coal-fields.
