Coal-Mine Accidents in the United States and Foreign Countries

Coal-Mine Accidents in the United States and Foreign Countries

Date: 1913
Creator: Horton, Frederick W.
Description: From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."
