Book Description
"Do coal mine operators use many mine timbers? What are the specifications for mine timbers? Does producing mine timbers differ from producing other sawmill products? These are typical of the questions that sawmill operators in the Appalachians ask about the mine-timber market. At first glance it seems strange that they would ask such questions. After all, the mine-timber market is a traditional outlet for wood products in the Appalachians, and it would seem that all sawmill operators in the region would be familiar with the market. But this is not the case. Sawmill operators, unless they sell mine timbers, know little about the market. Even those who sell mine timbers know little about the coal industry's current and potential need for mine timbers, because they generally supply only one or two mines. This report was prepared to answer some of the questions that sawmill operators have about the rnine-timber business in the Appalachian coal region. S3

Book Description
For every ton of coal they produce, the larger underground coal mines in the territory of the Birmingham Branch of the Southern Forest Experiment Station use more than three-fourths of a cubic foot of wood. Underground iron ore mines in the same area use one-fourth of a cubic foot per ton of output. In 1945, these coal and ore mines used about one-fifth of the 80 million cubic feet of timber products harvested in the Birmingham territory. Wood is needed in all underground mining operations in this territory. It supports the roof of the seam. It is used to build cars for transporting coal and ore, and it carries the rails for these cars. It is made into partitions for controlling ventilating air currents. It goes into necessary above-ground structures. For these and many other uses, wood has no economical substitute.
