Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 127-143, March 2026.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Study on Key Controlling Factors of Fracture Propagation by Shaped Charge Blasting in Coal Seams

open access: yesEnergy Science &Engineering, Volume 14, Issue 2, Page 721-736, February 2026.
Gas drainage is the fundamental approach to controlling gas disasters in coal mines. For single low‐permeability coal seams, it should be supplemented by coal seam permeability enhancement technologies to improve gas drainage efficiency. This paper conducted a numerical simulation study on the key controlling factors affecting the fracturing effect of ...
