... with previous findings on confined comminution which emphasize the tendency of grain size distributions to become self-similar through the elimination of same size neighbors at all scales. INTRODUCTION The limited ability to predict the onset and development of compaction at the pore scale in high porosity...

..., we investigated the effect of grain size on the stress-dependent flow behavior of a porous rock using the three-dimensional discrete element method. We modeled the porous rock geometry using randomly generated rigid spherical grains of given size distribution enclosed in a cuboid. Particle-particle...

... slabs was done and a petrophysical model was built using conventional and advanced logs to estimate properties such as porosity, permeability, water saturation, mineralogy, movable and irreducible fluids, and pore size distribution. Challenges arise from the complexity of the formation, limitations...

... intensity, edge and texture. On the basis of segmented images, the particle size distribution of the lunar regolith sample was extracted. The average density of the sample is estimated to be around 1582 kg/m 3 based on a calibration of the relationship between the image intensity and material density...

... ABSTRACT: An evaluation of the blasting performance at Erdenet Mine was conducted. Rock fragment size distributions were measured and analyzed with the digital image processing method employing the SPLIT_Desktop system. Regression prediction models were developed based on the field...

... on the cracking mechanisms operative in the sandstone material, we utilize statistical modeling techniques to identify three independent proxies that explain the inelastic deformation measured. The proxies, namely porosity, skewness of the particle size distribution, and ‘weak’ mineral content, are consistent...
