Show CREOSOTE PROLONGS LIFE OF MINE TIMBERS Mine timbers are subject not only to Insect attack, but also, what is more important, im-portant, to the action of gases and fumes that custnmarilv occur in mines, says the Mining and Scientific Press. These different dif-ferent destructive agencies cause the decay de-cay of the woofl, and as a result it is only six or seven years, on an average, says the Mining and Scientific Press, before be-fore -ui-h timbers become so weakened that constant repairs are necessary, even if they do not need to be replaced. It has been found that the life of the timbers tim-bers can be doubled, and even trebled by coating them with a creosote compound that fills all the pores on the surface of the timber, and thus prevents gases and fumes from reaching the wood. The coating coat-ing is a simple process, is not expensive, and tmids to eliminate repairs to the timbering tim-bering of shafts and other mine passageways passage-ways that have a comparatively long life. |
