Book Description
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. Consequently, arguments on this subject must be largely basedupon theory, and I have triedtogivea fairtheo retical View of 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.
