摘要
以某矿村庄下压煤短壁开采为工程背景,采用大型有限元工程计算软件ANSYS,模拟短壁开采中保护煤柱与关键层的受力状况和变形特征,得到了不同设计参数时的关键层和煤柱最大下沉量和变形曲线,分析了采宽尺寸变化对关键层下沉的影响规律,为短壁开采合理的开采参数设计提供了依据。
On the engineering background of the short - wall mining under the village of a coal mine, applying ANSYS, a large finite element engineering calculation software, simulates the force conditions and deformation char- acteristics of protecting the coal pillars and key stratums during the short wall mining, gains the maximum sinkage and deformation curves of the coal pillars and key stratums under different design parameters, analyses the influence laws of mining width size change to the sinkage degrees of key stratum, and provides a basis for the reasonable parameter designs in short- wall mining.
