Show Condition of Roads Is Seen in CoaS Mined 0 Close relationship between conditions condi-tions of roads and total tonnage of coal mined is seen in statistics compiled in a recent survey. These figures show that in Ohio,-for Ohio,-for example, where large sums of money have been expended iu recent years on roadlm provements, the annual an-nual output of pit mines, most of which also aro wagon mines, has jumped from 141,446 tons in 1914 to 2,739,900 tons in 1918. Given highways on which trucks can operate economically between mine and railroad, many wagon mines are finding It possible to compete in tho general market with mines located on railroads. Today, because of better transportation facilities and the increasing in-creasing demand for coal, some are producing several hundred tons of coal daily. The survey in which the figures and facts that have been cited are disclosed dis-closed was conducted by the economic research division of the Firestone Ship by Truck Bureau, at Akron, O. net |
