针对云南锡业公司松树脚锡矿缓倾斜中厚氧化矿体的开采技术条件 ,基于超前切顶、护顶空场法的采矿方法 ,采用非线性三维有限元数值模拟分析技术 ,优化选择了采场回采顺序和结构参数 ,从而为矿山生产提供了一定的理论依据
Aiming at mining technology conditions of moderately inclined moderately thick oxide ore body in Songshujiao Tin Mine of Yunnan Tin Industry Company, based on the mining method of advanced cutting top and roof caving method, the nonlinear three-dimensional finite element numerical simulation technology is adopted to optimize the mining technology. Field mining sequence and structural parameters, thus providing a certain theoretical basis for mine production
