Abstract

1,128,390. Mineral-mining methods. F. - W. PAURAT. 11 Oct., 1966 [24 Nov., 1965], No. 45277/66. Heading E1F. To ensure controlled collapse and settlement of the roof of worked out sections of a coal seam mined by the pillar and breast technique the pillars are, after the sections have been worked out, bored to ensure of subsequent collapse of the pillars.
