Book excerpt: Excerpt from Ventilation in Mines The high importance of a uniform and sufficient supply of fresh air for the life and health of the workers in mines, and indeed for the performance of the various operations therein, would seem to justify special treatment of this branch of the art of mining. The Authors first idea was to undertake a translation of Theophil Guibal's work on Ventilation; but more than twenty years have elapsed since the death of that authority, during which period great progress has been made in the ventilation of mines; and, especially as opinions and knowledge have undergone considerable modification with regard to the dangerous gases occurring in mines, it proved necessary to amplify Guibal's work and bring it up to date. One point that required introduction was the matter of respiration and rescue apparatus. Another was the cooling of the workings, surrounding rock, and the air of the mine, this question having been brought to the front of late, in consequence of the ever-increasing depth of mining operations, and the accompanying rise in the rock temperature; to which must be added, in the case of coal mines, the increase in temperature due to the absorption of oxygen by coal at the ordinary temperature. As is well known, continued exposure to high temperature is injurious to health, and, since the working efficiency of the miners is reduced in proportion as the pit temperature is increased, it is necessary to take steps to combat this unfavourable influence. Now the only way to do this effectually is to replace the usual, simple air ways by driving three, four, and more intake and return air ways in setting out the mine, thus considerably increasing the surface of contact between the air current and the gallery walls, reducing the velocity of the current, and prolonging the period of contact. The individual ventilating and working sections must also be reduced in size, and the excessive length of the air ways avoided.

Book excerpt: Excerpt from Modern Practice in Mining, Vol. 4: The Ventilation of Mines So far as the author is aware there is no work devoted entirely to a comprehensive consideration of the subject of mine ventilation, though there are several excellent books which treat of certain sides of the subject. It is hoped, therefore, that this little volume may be of some service to the young mining student in arriving at an elementary knowledge of the principles and practice of mine ventilation. For permission to use those of the figures which have not been specially drawn for illustrating the text, the author desires to tender his thanks to the various authors, manufacturers, and institutions from whom they have been borrowed.

Book excerpt: Excerpt from The Ventilation of Mines Enlargement of air-courses and splitting of the air-currents have been recommended as the most suitable mode of increasing the amount of ventilation, as well as the most economical means of distribution. Hitherto splitting of air has not been much resorted to in Scotland, although in other mining dis tricts it has been found to be the chief improvement in oh taining increased quantity.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Mine Gases and Ventilation Any one who has been closely associated with the practical operation of coal mines will realize quickly the need of technical knowledge relating to the safe and economical production of coal. In no department of the work is this need more urgent than in the ventilation of the mine. A knowledge of the properties and behavior of the gases found or generated in the mine, and the means for effecting their safe removal or rendering them harmless are of chief importance, requiring careful study combined with practical experience in the operation of mines. Experience, without a knowledge of the theory of mining, is little better than is the possession of such knowledge by one who has had no experience in the practical work. Experience and knowledge must go hand in hand. The problems relating air, gases, ventilation, safety lamps, breathing apparatus, rescue work, gas and dust explosions in mines are treated in a thoroughly practical manner, while at the same time showing their correct solution. Formulas must always play an important part in mine ventilation and their treatment is made as simple as possible. No effort has been spared to make this volume a standard of ventilating practice. With this end in view, the various constants used have been carefully selected and are those most generally adopted. Particularly is this true of the tables of weight and measures and the conversion tables relating to the common and metric systems given in the Addenda. Their use is recommended. The present volume, which replaces the little booklet issued by Coal Age, some time previous, under the same title, will be recognized as a second edition of that handbook, though greatly enlarged by the addition of whole new sections on Safety Lamps, Oils, Breathing Apparatus, Rescue Work and numerous tables, making it a complete treatise on the subject.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Underground Ventilation at Butte This bulletin on underground ventilation in the copper and zinc mines at Butte, Mont, was written in 1919 from data collected by Mr. Harrington during 1916, 1917, and 1918, when he and Dr. Lanza of the United States Public Health Service were engaged on a study of miners' consumption in mines of the Butte district. Largely on account of conditions arising from the World War, publication was deferred until this date, and its issuance now is because of the fact that it contains much up-to-date general information on ventilation in metal mines, though many of the Specific underground conditions described have since been materially changed.

Book excerpt: Excerpt from The Ventilation of Mines: Designed for Use in Schools and Colleges; And for Practical Mining Men in Their Study of the Subject The Ventilation of Mines is a subject to which all interested, miners and operators alike, should give the most earnest heed - miners, because upon the observance of its laws and principles depend their life and health; operators, because a thorough knowledge of the subject, followed by a faithful application of such knowledge in practice, cannot but result in a large saving of expense, ranging from fifty to seventy-five per cent. It is a subject to which as yet American writers have contributed little. This is to be accounted for partly on account of the infancy, as it were, of the Mining Industry in America, as compared with its development in the mother country; but largely on account of the inordinate haste of Americans to see results. This haste is only too apparent in all of our industries, but in none is it more observable than in the mining; and one of its most deplorable results is to hinder and in many cases render wholly impracticable scientific observation.

Download or read book Mining and Mine Ventilation written by Joseph James Walsh and published by . This book was released on 2015-09-27 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Mining and Mine Ventilation: A Practical Handbook on the Physics In adding to the number of text-books on Mine Ventilation the author aims to provide new material and to dwell more fully on the fundamental theories and laws of ventilation, and to furnish, if possible, to the student a more suggestive method of study in a more graphic form. While ventilation experts practically agree upon the essential theorems in ventilation, it is believed, however, that the subject may yet hold a new attractiveness and be more readily mastered if a few important principles, which are now generally misunderstood by the student, are magnified. The method of determining the size of fan, etc., to ventilate a mine under given conditions, together with certain facts pertaining to the water gauge, and the chapter on Mine Fires are entirely new features.

Fitch, Jr., Detroit, Mich.; The Jeffrey Manufacturing Co., Columbus, Ohio; The Colliery Engineer, Scranton, Pa.; M. B.
