Mining and Mine Ventilation: A Practical Handbook on the Physics. E-book. Formato PDF Joseph James Walsh   -  Forgotten Books, 2017  - 

All the general features contained in the first edition which students and others interested in the physics and chemistry of mining and mine ventilation, commended, have been retained in this revised edition. The chapters dealing with gases and mine ventilation have undergone revision, and new material added. The chapter treating of the sampling and analysis of mine gases is new, and has been written to supply a need which has arisen in teaching gas analysis and also to meet the growing demand for a more thorough knowledge of this branch of mining. In this chapter, mine gases are treated in a more practical way than is the custom in ordinary books on the subject. The properties of gases and the changes which affect their composition, together with the products of the combustion of gases, are clearly defined. The author appreciates the cordial reception given the first edition of his book and trusts the revised edition will meet with favor and speedily find a larger field of usefulness.
