Abstract: From the viewpoint of system engineering,the characteristics of mine rock engineering is re-examined,a concept of the system of mine rock engineering stability is formulated,and the conceptions of geological,design,and construction models are suggested,so that the problems of mine rock engineering stability can be solved with close combination of engineering geology,design,and construction.The dynamic monitoring and informationfeedback,and dynamic process of project construction enable us to get new knowledgw with which we can make new decisions for performance of an engineering project.
