Abstract:
A methodology for digital modeling of transient rock mass failure processes is proposed. It is intended to describe not only attainment of a limit state, but also the subsequent spatiotemporal kinetics of localization, fragmentation, and transport of failed material. The methodological framework includes the internal variable F characterizing the stage of transient failure, the generalized parameter Ψ of the failure-inducing action, the critical action parameter Ψc, the normalized action parameter Ψ/Ψc, an active-zone growth law, and mechanisms accounting for depletion of the available energy or structural resource. The physical meaning of the action parameter is specified separately for gas-mechanical, gravity-shear, and blasting processes, whereas the common structure remains “action parameter - critical value - growth - depletion”. A modified smoothed particle hydrodynamics method is considered for numerical implementation. It enables large deformations, free-surface formation, and fragmentation to be traced without prescribing the failure geometry a priori. The relation of F to degradation of stiffness, strength, and permeability is formulated. The need to control the Courant condition, smoothing length, artificial viscosity, contact parameters, and energy balance is demonstrated. Coupling of the geomechanical model with the gas balance of a mining panel and with a through calculation of blasting is considered separately. The methodology is intended for scenario-based assessment of coal-and-gas outburst hazard, rock mass stability, and consequences of dynamic action in solid mineral extraction.
