Study on the structural parameters of the upward horizontal layered filling method in deep gold mine

矿体围岩质量及应力对井下结构设计参数的选取具有显著影响,为进一步了解不同埋深对于采场结构参数的影响,通过力学试验分析了阜山金矿不同埋深情况下的力学性能。并在此基础上,采用经验计算和数值模拟的方法对阜山金矿矿区上向水平分层开采的采场结构参数进行了理论研究与数值仿真,分析比较了3种采场结构参数方案的应力与变形结构,优选提出了不同埋深下的采场结构最优参数。

The quality and stress of the surrounding rock of the ore body have a significant impact on the selection of underground structural design parameters.To further understand the impact of different burial depths on the structural parameters of the mining site,this article analyzes the mechanical properties of Fushan Gold Mine under different burial depths through mechanical tests.On this basis,theoretical research and numerical simulation are conducted on the structural parameters of the upward horizontal layered mining in the Fushan Gold Mine area using empirical calculation and numerical simulation methods.The stress and deformation structures of three mining structural parameter schemes are analyzed and compared,and the optimal parameters of the mining structure under different burial depths are proposed.
