空区稳定性影响因素数值模拟研究

Numerical Simulation of the Factors Influencing the Stability of the Empty Area

在矿山进行地下开采时,会造成许多空区,这些空区是否稳定对矿山安全有着很大影响,为了研究研究空区稳定性的影响因素,文章运用FLAC3D数值模拟软件建立一个简化模型对何家采区空区进行分析,从厚跨比进行了多组模型数值模拟分析,确定了几个因素对空区围岩及顶板稳定的影响,对生产实际有着一定的指导作用。

When underground mining is carried out in mines, many empty areas will be created. Whether these empty areas are stable or not has great influence on mine safety. In order to study the influencing factors of the stability of the empty area, the article uses FLAC3 D numerical simulation software to establish a simplified model to analyze the empty area of Hejia mining area. Multiple sets of models numerical simulation analysis is carried out from thick-span ratio, thus determining the influence of several factors on the surrounding rock and roof stability of the empty area, and has a certain guiding effect on production practice.
