Sentence examples for modifications of rock from inspiring English sources
Our study shows that the initial properties of the host rock (i.e. porosity and permeability) control the extent of hydrothermal alteration and the susceptibility to modifications of rock geomechanical properties.
The present work summarizes the studies conducted to date regarding the surface modification of rock dust particles for the purpose of eliminating or alleviating the problems accompanying coal mine dusting applications, meanwhile improving the dispersive properties of dust particles and the ability to suppress the coal dust explosion.
Previous studies have showed that the property and modification outcomes of rock asphalt (RA) is dependent on RA sources and their chemical components.
The deposition of quartz as pore-filling cement and/or veins is a common diagenetic process during burial sedimentation, and can cause dramatic modifications of bulk-rock mechanics, including changes in stiffness (Laubach et al. 2004), consolidation behavior (Karig and Morgan 1994), and frictional properties (Lockner and Byerlee 1986).
The coefficient for the permeability modification of the rock is assumed to be a function of the mean effective stress via a hyperbolic tangent function.
The diffusion can be fully uncoupled from the elastic deformations by neglecting the strain, but a less stringent condition can be obtained under uniaxial strain conditions, where the effect of the elastic deformations requires the modification of the rock stiffness involved in the diffusion equation.
