VIII.—Bursting Rock Surfaces [PDF]
Geological Magazine, 1887 The interesting note by Mr. Strahan in the Geol. Mag. for September, 1887, on explosive slickensides, reminded me of some similar phenomena which were not of unfrequent occurrence near Dent Head and Ribble Head in Yorkshire.In the limestone quarry from which the black marble of Dent is procured the workmen found that, when they were quarrying the lower

Rock burst governance of working face under igneous rock [PDF]
AIP Conference Proceedings, 2017 As a typical failure phenomenon, rock burst occurs in many mines. It can not only cause the working face to cease production, but also cause serious damage to production equipment, and even result in casualties. To explore how to govern rock burst of working face under igneous rock, the 10416 working face in some mine is taken as engineering background.
