Three-dimensional void fraction evolution law and sensitivity analysis of mining-induced overburden based on Bertalanffy time function

Abstract The voids in overlying strata caused by coal mining are prone to induce geological hazards. To reveal the evolution of overburden voids, a three-dimensional dynamic void fraction (VF) model based on the Bertalanffy time function was constructed and verified. Four evaluation indicators were...
