... ABSTRACT: Discrete Fracture Network (DFN) modeling is an effective tool to estimate the distribution of rock block sizes. However, for stochastically generated DFN, the clustering of rock blocks is often difficult to emulate, and the locations of high fracture intensity areas are often...

... 1. INTRODUCTION The MoFrac discrete fracture network (DFN) modeling software (MIRARCO, 2019) implements a rules-based methodology to generate plausible fracture networks guided by information derived from mapped data. (Junkin, et al., 2017; 2018). DFN models can range from entirely stochastic...

... are studied using synthetic rock masses generated by means of Discrete Fracture Network (DFN) models. RQD measurements are performed for rock masses with varying fracture intensity and by changing the orientation of the simulated borehole to account for orientation bias. The objective is to demonstrate...

The model used discontinuity orientation and spacing data from borehole drilling at the site, and discontinuity persistence data from wall mapping in a nearby pit...

... ABSTRACT: This paper presents a validation study for a new software tool, MoFrac, which generates realistic discrete fracture network (DFN) models. MoFrac implements aspects of a unique geostatistical and rules-based methodology for DFN generation. Non-planar fractures are generated through...

... was investigated. The main advantages of hybrid DFN-3DEC models for assessment of hangingwall sloughage potential are their capacity to represent the structural complexity of the rock masses (through the DFN model) and to address the effect of confining stresses on the unravelling process. 1. INTRODUCTION...

The approach differentiates between rock bridges failing under shear and those failing under tension. Without...

Discrete Fracture Network (DFN) modelling was identified as the most practical way to assess the potential for major kinematic instabilities as a consequence of movement upon major structures. Analysis of mapping, borehole and scanline geotechnical data, allows the spatial...
