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

Characteristics of instability and ejection modes of coal exhibiting strong impact inclination under uniaxial compression

Meitan kexue jishu
Mechanical behaviors of deformation, rupture, and ejection failure of coal with impact inclination under uniaxial compression were investigated. Uniaxial compression tests were conducted on coal with impact inclination at different loading rates.
