OSTI ID:6160785
The performance of approximately 115 shield supports employed in 2 panels at Kaiser Steel's Sunnyside No. 1 Mine is described. These Hemscheidt 320 HSL caliper-type shields were installed originally at Kaiser's York Canyon Mine as a demonstration program and later were transferred to Sunnyside. This report describes the rehabilitation of the shields prior to their installation at this second mine and the mining experience using these supports. One of the interesting features of the Sunnyside panels is the wide range in seam heights (from about 6 ft to about 10 ft) within each panel.
