RFPA3D Modeling and Application for Complex Rock Masses Based on SURPAC

doi:10.12068/j.issn.1005-3026.2018.07.023

Abstract

Abstract: Pre-processing function for RFPA^3D is not so strong that rock mass model with complex geomorphology could not be effectively and conveniently built. While SURPAC， a professional mining software， has a strong ability in modeling complex geological body. Besides， the requirement of unit types for both two softwares is hexahedral. On this basis， a method to build the model in RFPA^3D from SURPAC was proposed. According to the data relationship between the two softwares， a conversion program named STOR.m was developed in MATLAB to achieve the model conversion from SURPAC to RFPA^3D. The program was used in a slope instability analysis model in an open pit iron mine. Results show that the model conversion method can be applied conveniently and extends the application of SURPAC and RFPA^3D.

Key words: SURPAC, RFPA^3D, MATLAB, three-dimensional model, conversion program
