Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Hydraulic Mine Filling: Its Use in the Pennsylvania Anthracite Fields; A Preliminary Report The filler, after having been properly prepared, must be sent into the mine through a suitable opening. At many mines only bore holes are practicable. For such mines the best location of the bore hole is determined from examination of maps or other available data; sometimes from the best recollection of old-time miners. The latter necessity arises, in the case of old workings, because the maps of such workings, made at, a time when the mining engineer or surveyor was seldom considered necessary, are incomplete or unsatisfactory. The filler. After passing down the bore hole. ows unconfined into the inaccessible workings, causing blockages among the caves. And forming finally an effective permanent sealing pillar. In some mines this requires weeks of filling, and in other mines blockage is com plete in less than a dav. Under more favorable conditions, as in a mine where a fire may be in progress in live or producing work ings and where the filler can be transported to and deposited at pre determined points, the burning section is isolated so that the fire can not spread to adjacent workings, and the fire is allowed to burn to extinction within the sealed area.
