    • A comminution model for secondary fragmentation assessment for block caving 
      Gómez, René; Castro Ruiz, Raúl; Casali Bacelli, Aldo; Palma, Sergio; Hekmat, Asieh (Springer, 2017)
      Predicting the rock fragmentation obtained in drawpoints or secondary fragmentation is crucial in Block caving application since many engineering decisions are based on this key variable. These can include drawpoints size ...
    • Experimental quantification of vertical stresses during gravity flow in block caving 
      Castro Ruiz, Raúl; Gómez, René; Pierce, Matthew; Canales, Juan (Elsevier, 2020)
      Usually in block and panel caving mines, when the caving connects to the surface, monitoring of vertical stresses over production drifts is minimal due to the low probability of seismic events. However, when the stresses ...
    • Experimental study of the influence of drawbell geometry on hang-ups in cave mine applications 
      Castro Ruiz, Raúl; López, Sebastián; Gómez, René; Ortiz, Sebastián; Carreño, Nicolás (Springer, 2020)
      Coarse arches are a common issue in caving mines where large fragments are expected. These arches interrupt ore flow in drawpoints, decreasing available draw area, and also increasing the possibility of non-uniform draw, ...
