• -23- <br />• ; • CONCLUSIONS AND RECOMMENDATIONS <br />The coal of fhe Cameo "B" seam is exceptionally strong. Every effort should <br />- be made to take advantage of this condition. Pillars of 14 by 80 ft in size should <br />more than adequately support the loads resulting from the 50 by 100 ft area tributary <br />to each such pillar in the 3rd East and 2nd East Sections of the Roadside Mine and <br />• within 100 ft of the Ute Water Co's. surface facilities. These 14 by 80-ft pillars ore <br />more stable than those left in Pane! "G." <br />Backfill is recommended for the rooms within 100 ft of the Ute Water Co's. <br />surface facilities, not because it is needed for short-term stability but fo eliminate <br />the long-term potential of damaging subsidence effects. These long-term subsidence <br />effects become a real possibility many years, probably decades, after mining is complete, <br />r' <br />as the exposed pillars deteriorate. <br />I <br />l <br />L <br /> <br />
