Results of investigations as to causes of falls of stone and coal in underground workings and possible methods of preventing them; whole question of falls of roof is bound up with causes of rock movements; writer is inclined to opinion that most of rock movements that occur in underground workings are concomitant phenomena of colloidal nature of rocks. Translated from Technische Blaetter Wochenschrift zur Deutschen Bergwerks-Zeitung.
