| Abstract: | Big blocks interlocking and arch forming often occur in the process of transporting ore chute of Yichun Tantalum Columbium Mine. The structure, principle and characteristics of three popular explosive materials for uplifting and blocking are presented in this paper. It is thought that uplifting explosive pack using balloon is a better method. |
