摘　　要：无间柱连续采矿是一种高效的采矿方法,已成为地下矿山采矿技术发展的大趋势。以某铅锌矿山为例,采用能模拟开挖与充填的三维弹塑性有限元程序,对应用上向水平分层充填无间柱采矿法开采急倾斜厚矿体进行了数值模拟研究,分析了不同的分层高度和超前回采分层数,以及不同的暴露面积条件下采场的稳定性,从而得出合理的采场结构参数,为上向水平分层充填无间柱采矿法在矿山的应用和推广提供一定的依据。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.
