... fracture network. In this paper, a two-dimensional fracture propagation model is developed. The finite-discrete element method is used to describe the propagation of the fractures. In this model, the rock matrix units are discretized to obtain a discrete fracture network (DFN). The natural fractures...

... connected fracture network in siltstone when the reaction period is 24h. This is probably because the continuous pores between cementing minerals and grain particles provide a path for fracture propagation. Therefore, SCDA can produce long-connected fractures in siltstone in a short period once the fracture...
