摘要
针对湖北某矿采空区问题,在进行现场工程地质调查和室内岩石力学实验的基础上,利用Mathews稳定图法和有限元分析方法对其稳定性进行了论证,得出顶柱暴露面积应控制在600～900 m2之内等基本结论,为指导矿山安全生产提供了科学依据。
Based on engineering geology investigation and indoor rock mechanics test, the stability analysis of the mined - out areas at a certain mine in Hubei province was made by Mathews stability diagram approach and finite element method. The basic conclusion is that the exposed area of roof should be controlled in 600 to 900 square meters. It provided a scientific basis for the guarantee of safety in mine production.
