摘要： 夏甸金矿采矿活动已经进入深部，临近崩落法与充填法影响区域的采场受到多重扰动应力的影响，该区域围岩稳定性与采场尺寸的合理选取对矿山安全生产至关重要.采用先进的数字摄影测量技术，获取试验采场周围岩体结构面参数;并从多角度对采场围岩稳定性进行评价;在此基础上，运用Mathews图表法与跨度经验公式对试验采场的参数进行优化;最后，通过数值模拟，对得到的试验采场参数合理性进行分析与验证.图表法优化的采场尺寸在矿山开采的成功应用，验证了图表法在复杂应力下采场尺寸设计的可行性.

关键词: 数字摄影测量, 围岩稳定性评价, 节理裂隙, Mathews图表法, 采场参数优化

Abstract: The Xiadian gold mine has already experienced the deep mining， the stope by the caving method and filling method is affected by multiple disturbance stress. It is very important to determine the reasonable stope size and the stability of surrounding rock for the safety operation of the mine. The parameters of discontinuities around the experimental stope were obtained by using the advanced photogrammetry technique， and the stability of surrounding rock mass of the experimental stope was evaluated by multi-method. On the basis of this， the parameters of the stope are optimized by using the Mathews method and the span experience formula. Finally， through the numerical simulation， the rationality of the obtained experimental stope size is analyzed and verified. The successful application of the optimized stope size in the mine designed by Mathews method， verified the feasibility of the graphic method in the design of the stope size under complex stress.

Key words: digital photogrammetry, stability evaluation of surrounding rock mass, joint fissure, Mathews stability method, stope parameter optimization
