Abstract: Non-pillar continuous mining is high-efficient mining technology. It is a general tendency to carry out this mining technology in underground mine. Dipping at high angle and thickness ore-body with upward horizontal slicing and filling non-pillar continuous mining was briefly introduced as an example of continuous mining methode in a Pb-Zn mine. The elastoplastic three-dimensional finite element analysis technique was employed to simulate the practical excavation and backfilling mining activities. Stope stability status with different height of slice , the numbers of pre-slicing and the exposed areas was analyzed so as to provide the optimum stoping structural parameters for mine operation.

Key words: dipping at high angle and thickness ore-body, upward horizontal slicing and filling non-pillar continuous mining, stope structural parameters, the elastic-plastic three-dimensional finite elements
