FEM NTA coupling model is set up for simulation of mining conditions at great mining height with an overlying rocks of low tensile strength.
在重点模拟大采高条件下覆岩低抗拉特性的基础上，建立了“大采高FEM-NTA耦合模型”。The study is the basis of solving strata control around coal face and ground sinking assessment with large mining height.
此研究是大采高条件下采场矿压控制、地表塌陷评价的基础。Here, the working encountered large mined-out area at one side and free surface of hill slope at the other side.
