TL;DR: In this article, a fully coupled 3D hydro-mechanical model with real porous seepage is presented for simulating hydraulic fracturing, which can capture crack initiation and propagation, and the fluid pressure evolution during hydraulic fracturing.

TL;DR: In this paper, an integrated shed system based on backfilling of chemical grouting material behind yieldable steel sets is proposed to efficiently support and stabilize the roadways in loose thick coal seam.

TL;DR: In this paper, three extensions to the traditional discontinuous deformation analysis (DDA) method are tested to simulate the entire process describing the behavior of landslides induced by reservoir impoundment.

TL;DR: Based on the finite-discrete element method (FDEM), a 2D fully coupled model with real pore seepage is proposed in this paper, which can solve the problem of the deformation and fracture of porous medium driven by fluid.

TL;DR: In this article, a two-dimensional coupled hydromechanical discontinuum model for simulating the rock hydraulic fracturing process is presented, where the calculation of fluid mechanics is performed first to obtain the seepage pressure near the tips of existing cracks, and then the fluid pressure is treated as linearly distributed loads on corresponding block boundaries.
