Description:Excerpt from Sampling and Examination of Mine Gases and Natural Gas: A Revision of Bulletin 42 In this bulletin, the style of Bulletin 42 has been closely followed. Much of the material is reprinted on the following pages in its original form, and changes have been made only where manifestly necessary. Laboratory methods have been brought up to date. Some types of apparatus described in Bulletin 42 have now become obsolete and newer designs are described instead. The authors hope that this bulletin will be of as much service as was Bulletin 42. Acknowledgements Revision has necessitated the inclusion of data that have been published within the last few years. Proper credit is always given the authors of such material by references to the original articles. The reviewer especially acknowledges his use of information taken from papers prepared by R. R. Sayers, W. P. Yant, G. G. Oberfell, M. C. Teague, I. W. Robertson, F. N. Neumeister, W. C. Harpster, W. L. Parker, S. H. Katz, J. D. Davis, and A. C. Fieldner. Introduction To Bulletin 42 The Bureau of Mines, as part of its designated duty of investigating the causes of mine accidents, is conducting at its experiment station in Pittsburgh, Pa., a study of mine gases. Some of the work already done in connection with this study is outlined below. A large number of samples of mine gas have been collected under normal conditions in returns and in splits, and at other points in the Ventilating current; also at the face, in the goave or gob, in unventilated places, and Wherever the air was still. Samples have also been obtained under abnormal conditions, as after explosions and while mine fires were in progress, or from sealed areas behind stoppings and dams where the air had been stagnant for some time.
