Two of the main advantages of the hybrid approach include the capability of studying the potential impacts of isolated draw on cave growth and point loading on the extraction level, as well as the effect of including, explicitly, the airgap and mechanisms of fines migration and rilling on cave growth and subsidence. The focus of this tutorial is to provide you with a basic famil. The procedure is repeated until the draw schedule used as an input in REBOP is finished. This tutorial steps through the actions necessary to quickly create and solve a FLAC3D model.

After determination of the new stresses for the step, the hardening parameters for the zone are updated following the procedure described above. Versions 5 and 6: After installation, copy and replace the file in the Crack folder in the program installation location.

FLAC3D informs REBOP which zones (initially inactive) could now be mobilised. The implementation of the strain-softening/hardening model in FLAC3D proceeds as indicated in the Mohr-Coulomb model description. Latest Version: 6.00.74 (Description) Released On: Saturday, Feb. FLAC3D solves stresses associated with the presence of these zones and estimates the yielded zone surrounding the cave. After one cycle of extraction, REBOP informs the location of the movement zones and the presence of air, if it exists, to the continuum FLAC3D model. CN106227930A CN201610570888. David Russell, FLAC3D Product Manager and Lead Developer. The approach simulates the caving process by explicitly modelling each isolated movement zone derived from REBOP into FLAC3D to determine the yielded zone and cave back associated with mass drawn. This video is a recording of a one hour webinar reviewing the latest features in Version 6 of FLAC3D (currently available as a pre-release).
For apply conditions that work on gridpoints, the first argument is a pointer to the gridpoint and the second argument is not used. The results of the model can be used to derive estimates of: (i) caveability and caving rate, (ii) abutment stresses and cave loads, (iii) recovery and dilution entry, (iv) fragmentation, and (v) breakthrough timing and subsidence. For apply conditions that work directly on faces, the first argument is a pointer to the zone and the second argument is an integer from 1 to 6 indicating the face. The hybrid REBOP–FLAC3D approach allows prediction of the limits of the geomechanical zones defining the cave as a function of production.
