Research on Crack Propagation and Stress Propagation in Coal‐Rock Combinations Under Different In Situ Stresses Subjected to Blasting Loads

Energy Science &Engineering, EarlyView.
A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.

Multiphysics Coupled Response of Stress and Seepage in Coal Under Borehole Disturbance and Optimization of Borehole Parameters

Energy Science &Engineering, EarlyView.
One‐way FLAC3D‐COMSOL coupled modeling and field validation show that a 150 mm borehole radius with 5 m spacing provides the best coordination of plastic‐zone expansion, stress relief, permeability enhancement, and gas‐pressure attenuation, increasing the pure gas drainage rate by 35.4%. ABSTRACT To rationally determine the borehole radius and borehole
