Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

open access: yesDeep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

open access: yesDeep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Clays, Clay Minerals, and Pesticides

open access: yes, 2013
Design and test of clay-based formulations of pesticides for solving environmental and economical problems are described. Organoclays were mainly designed to promote the adsorption of neutral and hydrophobic pesticides and slow their release. Adsorption of organic cations modifies the nature of the clay mineral surface, transforming it from hydrophilic

Soil organic matter and mineral content as crucial factors for the fate of tetracycline in soils

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Soil self‐cleaning ability and bioavailability of different pollutants are strongly dependent on the soil properties. It is not easy to determine effects of individual soil characteristics because they can impact together often in a synergic effect.
