摘要
金属矿山实现采矿连续工艺已成为采矿技术发展的大趋势，无间柱连续采矿是井下高阶段、一步骤回采的高效采矿技术．作者在阐明无间柱连续采矿技术思路和优点的基础上，采用有限元数值模拟法，对地下金属矿山阶段开采留间柱和不留间柱以及不同回采顺序的地压规律进行多方案分析和比较，为无间柱连续采矿的应用提供了理论依据．
It is a general tendency to carry out continuous mining in underground mine.Non pillar continuous mining is regarded as a high efficient,high level and one step mining technology. Based on the concept of non pillar continuous mining, this paper uses finite element numerical simulation method to compare and analyze stability status (including stress and displacement) of pillar/non pillar mining method, with different stoping sequence. These results provide theoretical basis for application of non pillar continuous mining.
