Abstract:A recently-developed three dimensional (3D) elastoplastic finite element program software on microcomputer was introduced,which finds effective application in mining engineering,such as multi-stage excavation,back-filling,caving,construction,etc.A symbol-identified input data system, parallel module structure and mesh auto-generation are some of the characteristics of the program. Two test examples are presented to verify the program software.

 

Key words: mining engineering excavation back-filling numerical simulation
