The gangue filling mining method is used to reduce the occurrence of dynamic disasters on roof a steeply dipping coal seam (SDCS) effectively and improve stability overburden structure. To comprehensively study movement law under different quantities, 3221 working face Lvshuidong mine was taken as research site. vertical displacement, stress, plastic zone quantities were analyzed by using FLAC3...

Hydraulic fracturing is a prospective technology for methane hydrate deposit exploitation. The evolution of hydraulically stimulated fractures around the point liquid injection simulated. For this purpose, FLAC3D computer model used because its explicit calculation cycle that imitates real physics, prevents numerical instability, and reproduces realistic path during simulation nonlinear rock ma...

With the increasing complexity of engineering geological conditions, problem tensile-shear failure bolts is becoming more serious. Accurate modelling performance bolted rough joints subjected to load essential for support design. In this paper, based on theoretical criteria bolt failure, mechanical model Pile element in FLAC3D program modified, and accuracy modified verified by numerical experi...

The construction of undercrossing roads often has an adverse effect on the upper existing railway line, and can cause uneven subsidence crossed section. In response to influence new road high-speed bridge, a highway passing under bridge was taken as research object. Based FLAC3D finite difference software, computational model established analyze structural deformation bridge. results show that ...

Abstract Numerical modelling has become an important tool in the underground rock bolt reinforcement designing process. provides advantage of easily and quickly simulating complex geometries mechanisms with sensitivity analyses. However, a numerical model needs to be calibrated using mathematical solutions, lab testing or actual in-situ observations measurements (which is preferred method) befo...
