摘　　要：运用正交有限元原理,对影响矿体开采的主要结构参数进行正交试验分析,用三维有限单元法求得矿体开采在数值模拟极限状态下的顶板极限厚度,并采用多元线性回归的方法推得矿体顶板极限厚度与主要开采结构参数之间的关系式,然后用工程实例验证了推得关系式的可靠性。Based on the theory of orthogonal finite element, the experiments are arranged with the different structural parameters influencing mineral excavation. The depth of rock covers in the limited state of numerical simulation are obtained using three-dimensional finite element method. And a multiple linear regression equation between the depth of rock covers and the mineral excavation parameters in the limited state is educed. The reliability of the equation is verified by an engineering example.
