Abstract: During deep mining process,mining-induced stress may serve as the principal factor for stope pressure bump,coal slide,roof collapse and even geological disasters from rock outburst. The space-time variation rules of mining-induced stress during the basic production unit deep mining process are studied,and the refined modeling of deep stope is proposed to build the level modeling of mining rock mass,the dynamic simulation model of mining action,the metamodel of multielement heterogeneity mining rock mass and the auto-adapted optimal model for the designing parameterization of dynamic mining control. Also such technologies,as static scene modeling technology,dynamic simulation technology of production processes,dynamic visualization techniques of mining-induced stress field information design scheme preview techniques of dynamic control,are integrated as a synthetic integrated system of deep stope mining. By exploring the dynamic decoding rules of the variation between the mining action and the rock mass metainformation,the space-time variation laws of the mining-induced stress are revealed. All these provide a guide for selecting the mining method,forecasting the supportive timing and location,and optimizing the mining parameters,and also propose a scientific and technological support for the safe production.
