Book excerpt: Excerpt from Examination Questions for Certificates of Competency as Mine Inspector, Mine Foreman, Mine Manager, Fire-Boss, Hoisting Engineer, Etc: As Given by the State Examining Boards Nearly all the coal-mining states now have an inspection service; and in many states the appointment or election of the inspector is based on a preliminary educational test, combined with a certain period of practical experience in mining. In many states, an educational test is also required, in addition to practical experience, for other official positions about the mines, and this list of states is constantly increasing, for it is a recognized fact that coal mining is safer under certificated and educated officials than under those who are not thus equipped. A mine of today is a very different proposition from one of 30 years ago; and the applications of steam, compressed air, and electricity on the sur face and underground, and the working of deep, thin, gaseous, and watery mines have introduced problems in mine management that require technical knowledge for their solution. The questions and answers given in this book are mainly those that have already appeared in The Colliery Engineer and Metal Miner, or in Mines and Minerals; the answers as originally given have been edited and rearranged so that there may be as little duplication as possible in question or answer. Certain questions have been added from a file of unpublished examina tion questions, and it is thought, therefore, that this compilation faithfully and fully represents the range of subjects covered at the present time by examinations for certificated mining positions in the United States and Canada.

The airways are very large and are kept up and in good condition. The volume of air is nearly three times the quantity required by law, and yet complaints are made of the ventilation, and it is a long time after a shot is fired before the smoke gets cleared out. What do you think is the matter? M.--///. Ans.--There should be no trouble on the entries of the mine under these conditions. The air may not, however, be properly deflected into the rooms or chambers and made to sweep the working faces as it should. It may be necessary to put up curtains on the airways to deflect the air into the rooms. Again, the sectional area of the airways, which are very large, may be such that the velocity of the air is too small to remove the gases and smoke rapidly when a shot is fired, although a large quantity of air may be passing; this is often the case in thick seams, where the airways are very large. Ques. 1314.--In a mine employing 250 persons, each person being allowed 200 cubic feet of air per minute, give the total volume of air required in a day of 10 hours, in cubic feet and its weight in tons, the temperature being 62 F., and the barometer 30 inches. F.--Pa. (B) Ans.--The number of cubic feet of air circulating through the mine in the given time should be 250X200X60X 10 = 30,000,000 cu. ft. The weight of 1 cu. ft. of air at the temperature and pressure given is 1.3273X30----=.07624 lb. 460+62 The weight of air that should circulate through the mine in 10 hr. is, therefore, .07624X30,000,000 = 1,143.6 T. Ques. 1315.--What is the smallest quantity of air required to be circulated per minute to make safe a section of a mine, under the following conditions: In the section, there are two entries and fifty-five rooms. The entries are..
