Synopsis
Excerpt from A Text-Book of Coal-Mining: For the Use of Colliery Managers and Others
IN the preparation of this volume my aim has been to supply a text-book of moderate dimensions, giving all the information with which the student and the practical miner should be familiar. In order, however, to economise space, I have had to omit reference to many appliances which have become obsolete from their antiquity, or by reason of their failure in practice.
Although it is impossible within the limits of the book to furnish exhaustive descriptions on all points, yet the details of general colliery work have been fully described, on the ground that collieries are more often made remunerative by perfection in small matters, than by bold strokes of engineering. All modern collieries are practically identical so far as general machinery and arrangements are concerned; nevertheless, it frequently happens, in particular localities, that the adoption of a combination of small improvements any one of which viewed separately may be of apparently little value, turns an unprofitable concern into a paying one.
At the end of each chapter will be found a carefully selected list of Memoirs in which fuller information can be sought. This will, it is hoped, prove a novel and useful feature in a treatise on coal-mining, for, scattered through the pages of the Transactions of the Mining Institutes, numerous valuable papers exist; but, owing to the lack of general indexes, they are unfortunately not consulted so much as they deserve to be.

Product Description
Excerpt from A Text-Book of Coal-Mining: For the Use of Colliery Managers and Others This Edition has been thoroughly revised, and the size of the book has been considerably increased by the introduction of additional matter dealing more especially with the use of compound and electrical winding engines, and with the application of central condensation stations. Nearly two hundred figures were added to the fourth edition to illustrate, as far as possible, the most recent appliances, and the opinions that have attracted attention during the last half decade. These have been retained, and additional ones inserted in the present issue. Year by year the more easily worked coal deposits become scarcer, and operations have to be carried on in deeper areas, or in seams presenting difficulties that have hitherto hindered their development. The mining engineer of the future will have to deal with commercial and technical problems that will tax his resources to the utmost. There is, too, little doubt that labour will also claim a greater proportion of the profit than it has in the past. The influence of this factor on the prosperity of the mining industry can be minimised only by the introduction of labour-saving appliances, by increased knowledge on the part of the engineer, and by a readiness to avail himself of improvements, which his own ingenuity, or that of his fellow-workers, may suggest. It is hoped that the information contained in this volume may help to remove local prejudices and to suggest ways in which the experience gained in other districts may advantageously be applied. I have to thank Mr. G. Stephen Corlett for revising the electrical portion of the work, and I am again indebted to Mr. Bennett H. Brough and Mr. H. G. Graves for valuable suggestions.
