摘要
矿体稳固性较差条件下,采场高度的确定及其安全开采一直是国内外矿山面临的一项难题。针对某铜矿中厚以上矿体采用分段凿岩阶段出矿的采矿技术方案,采用三维数值模拟的方式,在保证采场回采稳固性的条件下,从围岩的变形、应力和塑性区几个方面对采场极限高度进行分析。最终确定采场合理高度。
Determination of stope height and safe mining is always a difficult problem faced by mines at home and abroad under the condition of poor orebody stability.In view of a certain copper ore body above medium thickness,the stope limit height is analyzed from the aspects of deformation,stress and plastic zone of surrounding rock under the condition of ensuring stope stability by means of three-dimensional numerical simulation.Finally determine the reasonable height of stope.
