Nowadays, the numerical simulation method is an essential tool in the stability analysis of mining engineering, and it is important to ensure the accuracy and reliability of the mining engineering design to construct a numerical model used as a more realistic representation of the in situ situation.

Numerical simulation programs widely used for stability analysis of geotechnical and mining engineering structures are FLAC3D and ANSYS, etc.

Han Un Chol, a researcher at the Science Engineering Institute, has proposed a fast and convenient modeling technique by combining ANSYS and FLAC3D with unique advantages for numerical calculation and SURPAC suitable for 3D modeling.

First, he examined the relationships between the data structures of the model files for SURPAC, ANSYS and FLAC3D, and established the transformation technique of an integrated 3D solid model via Excel.

Then, he applied the proposed method to the analysis of the pillar stability for sublevel open stope method in the target mine.

Finally, he verified the validity and feasibility of the proposed model transformation technique.
