Timber treating operations at United Verde Mine, Jerome, Ariz.
Mine is well ventilated and no excessive timber decay is experienced in main gangways or sill workings; in pillar mining, rotted flooring has often given trouble; stringers supporting chutes and manways in stopes are difficult to replace and treated timber is desirable; zinc chloride was chosen; Ac-Zol is used for painting framed ends of shortened posts; also used on shaft guides; description of plant; cost of treating adds approximately 30% to cost of timber.
