Abstract

Abstract: To obtain an easily method of FLAC3D modelling and reduce the difficult of using of FLAC3D, a program is developed using python. This program using the stratigraphic information to generate the discrete grid points based on Kriging interpolation first. And then the program can generate the FLAC3D grid format file automatically. The generated file can be imported into the FLAC3D software and a 3D model can be obtained directly and easily. It is faster and easier than using the inner modeling script. The program provides three basic elements model of the FLAC3D. The method can generate accurate 3D model using the Kriging interpolation. Three applications and some results of coal mines are given in the paper. Those applications show that it can generate accurate 3D model for complex topography. The research results provide a tool for building 3D models in complex geo-conditions simulation.
