An important practical application of this finding was the field use of logged angular spans of breakouts...

Results indicated that the box fractal dimension can capture the combined influence of joint size distribution and joint density...

... that reflects the deformation behavior of irregularly shaped particles. Two-dimensional models also tend to overestimate the volumetric strain response of dilatancy relative to compaction because of the differences in porosity in three dimensions compared to areal density in two dimensions. Accordingly...

The object of this calculation was to understand the effects on the pillars of the winning of a nearby face and the influence of a fault crossing both the face panel and the shaft area. Besides, since the end...
