Numerical modeling of failure mechanisms in phyllite

2014-11-1  An occurrence of buckling as a local failure mechanism in a mine slope at QF is shown in Fig. 7. It occurred in a phyllite slope of a gold open pit mine and it affected only a small portion of the bench slope. Lopes demonstrated that this failure mode had no influence in global slope stability [1].

Sorption of uranium(VI) onto phyllite - ScienceDirect

1998-10-1  Phyllite is a low-grade metamorphic rock classified as greenschist facies. It has thin-shaly foliated texture and is formed from pelitic rocks. Phyllite is quite common in the Western `Erzgebirge' in Saxony, Germany and is intimately associated with uranium mining in the former East Germany.

Deformation and failure mechanism of phyllite under

2012-11-20  Phyllite failure occurs from the initial thermal damage of the rock materials, splitting and softening (which is caused by pore water pressure), and the pressure difference which is formed from the loading axial pressure and unloading confining pressure. The phyllite failure mechanism is a transtensional (tension — shearing) failure.

Phyllite - an overview ScienceDirect Topics

Ductile deformation structures develop widely in various metamorphic rocks, such as slate, phyllite, schist, and gneiss. All these types of rocks exhibit easily recognized foliation (i.e., planar or layered structures) or lineation (i.e., linear structure) and occasionally fold (i.e., bent or curved planar structure) structures at varied scales. For example, slate is a low-grade metamorphic rock generally derived

Sericitic Phyllite as Addition in Portland Cement ...

Pozzolans are materials that when milled are able to react with the cement, forming compounds with binder properties. Seeking to reduce costs and improve Portland cement performance, the cement industry has used mineral additions such as pozzolans, partially replacing clinker in Portland cement. Sericitic Phyllite is a metamorphic rock, considered sterile by iron mining.
