Show MAKE THE MINE TIMBERS LAST mine owners find that it is absolutely necessary to keep all timbers used in the interior of the mines in the best of condition as in years past many cave ins and accidents have resulted from the deterioration of the timbers these timbers used as supports and struts across the top of the passage ways in the mines are subject to the action of gases and fumes which occurs in the mines and also to insect attack these different destructive agencies cause the decay of the wood and as a result the timber lasts only about six or seven years on the average of course they may not actually fail at the end of that period but beyond that time their condition is such that they are considered unsafe it has been found that the life of the timbers can be doubled and even trebled by coating them with a creosote compound which will fill up all the pores on the exterior of the timber and prevent gases fumes etc from acting on the wood the coating of these timbers is a very simple process and is quite economical when it is considered that the life of the timbers will be greatly lengthened and constant repairs along the shafts and passageways eways in the mines eliminated as was the case when uncoated timbers were used it is readily seen that this creosote covering will be a very profitable investment for mine owners |
