This handbook, Safety in Coal Mining, has been prepared at my request by the chairman of the mine safety board of the Bureau of Mines. The purpose of the handbook is to make available in convenient form a concise statement of practices and methods recommended by the bureau for the increase of safety in coal mining.
Rapid growth in the use of machinery for cutting and loading coal, longer haulage ways, and the wider use of mechanical haulage have contributed toward economy in mining by making possible a larger output of coal without a corresponding increase in the number of workers. At the same time this mechanicalization of the mines has been accompanied by increased hazards from falls of roof and coal and from accidents in transporting the coal from the face to the tipple. Incidentally, also, the machines have introduced new hazards peculiar to themselves, although these hazards can not be classed among the major causes of mine accidents.
Progress in accident prevention is indicated by either a larger output per accident or fewer accidents per employee; double progress is realized when increased production per accident accompanies a reduction in the accident rate per employee.
It is hoped that this publication will prove helpful to safety engineers, mine owners, mine employees, and others in their endeavor to obtain the Nation's necessary fuel at a minimum cost in life and limb. The bureau plans to revise the handbook from time to time as developments in the industry, and further study and research, seem to warrant.
