SPH simulation study of automatic top coal caving flow process based on elastoplastic soil constitutive model

The top-coal caving technique is an effective method for extracting thick or ultra-thick coal seams, with numerical simulations commonly employed to study the caving and coal release processes. However, current discrete element-based numerical models are limited in terms of parameter determination,...
