Abstract

A total of 142 prismatic specimens were prepared from five different Appalachian coal seams for direct shear-strength tests. Two types of specimen fracture were observed. The shear stress versus shear displacement and normal displacement for each specimen were recorded and analyzed. Two linear regressions were derived to best fit the shear failure of the coal.
