APPLICATION OF THE BRITTLE FAILURE CRITERION TO THE DESIGN OF ROOF SUPPORT IN THE SOFT ROCKS OF COAL MINES (2011)
<p>The bilinear brittle failure criterion that utilizes the unconfined compressive strength (UCS) and a spalling limit of 3.4, together with a tensile strength cut-off can be used to model the height of failure above coal mine roadways. Transverse isotropy ...

Seedsman, Application of the Brittle Failure Criterion to the Design of Roof Support in the Soft Rocks of Coal Mines, 11th Underground Coal Operators' Conference, University of Wollongong & the Australasian Institute of Mining and Metallurgy, 2011, 60-72.
The assessment of the stability of coal ribs needs to consider not only the impact of the cleating and jointing in the coal but also the possible onset of failure of the coal itself. The same planar, wedge and toppling failure modes seen in pitwall slopes ...
