Abstract: In mine engineering, rock orebody extraction or mining can induce a redistribution of the surrounding rock stress, lead to rock failure due to stress concentration, brining a serious safety problem to the mine production and construction. Therefore, it is very necessary to analyze and study the surrounding rock stability in extraction or mining, locate the dangerous sites and work out preventative and control measures. The paper describes the application of the Rock Failure Process Analysis System in the analysis and study of the surrounding rock stability in the mining engineering of TangSteel Shirengou Iron Mine and the formulation of the safety mining plan, which has successfully guided the mine production practice.

Key words: Rock failure process, Analysis system, Stability of surrounding rock, Mining engineering
