The compaction behavior and particle crushing during compaction of the crushed sandstone–mudstone particle mixture, which is used as a filling material, are investigated in the present study. The value of the maximum dry density, deduced from a standard compaction test, ranges from 2.08 to 2.13 g/cm3, and that of the optimum moisture content from 8.18 ...

Particle Crushing in Granular Assemblies
AIP Conference Proceedings, 2009Idealised assemblies of equally sized spherical particles are subjected to a range of macroscopic compressive principal stresses and contact forces are determined. Stress fields within individual particles are studied and a failure criterion for brittle materials imposed indicating that crushing occurs when the maximum contact force reaches a threshold

Particle crushing in hydrate-bearing sands
Geomechanics for Energy and the Environment, 2020Abstract The depressurization of natural hydrate deposits to produce methane gas can increase the effective stress in hydrate-bearing sediments, which may induce sand particle crushing. Sand crushing may become detrimental to gas production, because the breakage of sand particles can cause sediment contraction, reduction in permeability, and the ...

Abstract The present study focuses on the compaction behavior and particle crushing, during the compaction, of a crushed sandstone–mudstone particle mixture. Compaction tests and sieve analysis tests, in laboratory, were performed. The effects of the mudstone particle content, by weight, on the maximum dry density, the optimum moisture content and ...

Seepage properties of crushed coal particles
Journal of Petroleum Science and Engineering, 2016Gas release from the crushed coal formation during coal mining poses a threat to the normal storage and gas transport within coal seam. This sort of release is largely related with the evolution of gas seepage properties of crushed coal, namely, the evolution of gas seepage properties plays an important role in the gas extraction and the outburst ...

Journal of Geotechnical Engineering, 1985
In order to understand the physics of the strength and stress‐strain behavior of soils and to devise mathematical models that adequately represent such behavior, it is important to define the degree to which the particles of an element of soil are crushed or broken during loading.

Particle Breakage of a Crushed Sandstone–Mudstone Particle Mixture
2021Sandstone–mudstone particle mixture (SMPM) is often used as a main filling material in many agriculture-related and civil engineering works such as in rockfill dams and filling foundations. The SMPM was found crushed seriously since it is mixed with mudstone particles.

Impact crushing of particle–particle compounds—experiment and simulation
International Journal of Mineral Processing, 2005Abstract Particle–particle compound consists of various sized particles with non-uniform properties, whose properties vary in large range depending upon applications, methods of manufacturing and ratio of its compositions. The different types of engineering agglomerates and building materials, like concrete, are some of the examples of particle ...

Significance of Particle Crushing in Granular Materials
Journal of Geotechnical Engineering, 1996Particle breakage occurs when the stresses imposed on soil particles exceed their strength. To quantify the amount of breakage, many particle breakage factors have been proposed. Correlations of particle breakage parameters with standard soil parameters such as effective mean normal stress at failure and void ratio at failure do not provide a fully ...
