Excerpt from The Mechanical Engineering of Collieries, Vol. 1 Then in dealing with centrifugal ventilators, there are contradictory ideas as to the form of fan which really gives the best results. The results of different fans, and even of the same fan working at the same pit vary so much that practical results certainly do not decide the question.

Book Description
Excerpt from The Mechanical Engineering of Collieries, Vol. 1: 1. Boring; 2. Shaft Sinking; 3. Surface Arrangements; 4. Shafts and Headgears The mechanical engineering of collieries, then, is of growing importance, and much still remains to be done. The question of winding from great depths remains to be satisfactorily solved; and the utilisation of slack and waste from collieries might receive with advantage more attention, and in this respect the question of generating electricity at coalpit centres is important. No quite satisfactory appliances have ever yet been invented to prevent the cage falling in the ease of a broken rope, and the sad accidents due to this cause are to be regretted; though when we consider the vast number of men who descend and ascend daily into and out of mines, it speaks volumes for the careful and efficient supervision and atten tion to winding ropes and arrangements, especially in our own country, where safety appliances are practically unheard of. With the growth of the mechanical appliances in and about a mine and with the introduction of electricity, the responsibilities of the colliery manager have increased, and a colliery manager, instead of being merely a mining engineer, must now be a competent mechanical and electrical engineer, and hence the training of colliery managers has given rise to much discussion. Whether it is wise to expect a colliery manager to have that knowledge and experience in mechanical and electrical engineering - each in themselves separate professions, requiring years of training - and at the same time to be an expert mining engineer, capable of directing the operations of working and winning large areas of coal, with all its attendant difficulties and dangers, requiring by Act of Parliament an apprenticeship or training of not less than five years, is a question to be decided. Abroad, it is said, the colliery manager is more highly scientifically trained, but it is also said he is not such a good pitman. It is to be hoped, therefore, that with the development of the mechanical and electrical engineering of collieries, in our own country at least, the colliery manager will not neglect that first and necessary qualification, to be - what he has hitherto been - a mining engineer par excellence.

Book Description
Excerpt from The Mechanical Equipment of Collieries The present writers - his son on the one hand and his closest colleague during the last fifteen years of his work in mining education on the other - have ventured to undertake that duty, although not without misgivings, well knowing their inability to fill the few gaps in a manner worthy of a place side by side with the rest of the work, and fully alive to the many imperfections and shortcomings in those portions for which they are responsible - imperfections which would have been absent had the author been spared to complete his work. So far as possible the original manuscript has been printed as it left his pen, the pen of a ready writer, unaltered except in so far as it has been necessary to bring the matter up to date. In those portions which it has been necessary to add, fortunately not many, the editors have endeavoured to express the views and lay down the principles which they knew to be those of the late author. Special attention has been given to the illustrations, many of which are detailed drawings of plant and machinery actually installed and working at modern collieries. Considerable care, too, has been given to the chapter on electricity, the desire of the editors being to place this important subject before their readers in as useful 3. Form as possible, recognising as they do the prominent part which electrical engineering is bound to play in the mechanical equipment of the modern colliery. Valuable assistance has been rendered by a number of engineering firms specialising in colliery appliances, and the editors have adopted the course of recognising and acknowledging that assistance in the text, wherever they have availed themselves of the information so kindly placed at their disposal.

Book Description
Excerpt from The Mechanical Engineering of Collieries, Vol. 2 of 2: 7. Haulage, 8. Pumping, 9. The Generation and Transmission of Power, 10. Coke Ovens A. - 1. At the coal face the only way of handling the tubs is by hand, the empty tub being put into the stall by a strong youth termed a putter, and when filled removed by him. If the tub is very large, or the gradient heavy, so that this work is too heavy for manual labour, a small pony is employed in charge of a youth, the operation being termed pony putting. The workings, however, are driven to avoid gradients as much as possible, and as the workings are constantly being moved forward, the road usually consists of short lengths of bridge rails about 4 ft. Long, with holes in the flanges which are nailed to cross sleepers of woodt - these latter being of larch, or fir, from 3} to 6 inches in width, and 2§ to St inches in depth. This road is led into the face, and the two front wheels Of the tub are allowed to drop over the end on to the thill or floor of the seam, which gives the extra height of the rails and sleeper between the top of the tub and roof for filling.
