Subsidence from mining
Various cases of phenomena of surface subsidence that accompany excavation of horizontal bed are illustrated and discussed; requirements for pillar to support point on surface; discussion by second author urges that final angle of plane of draw is determined by counterbalancing of various forces involved. (see also - (discussion) p 132-133; Am. Inst. Min. and Met. Engrs. -- Tech. Pub., no. 182, Feb. 1929, 6 pp)
