基于UDEC的开挖过程中覆岩移动规律研究

Study on movement law of overlying strata in excavation process based on UDEC

为了研究开挖过程中下沉覆岩移动规律,根据山西汾西瑞泰井矿正明煤业有限公司0401工作面的地质资料,利用UDEC数值模拟软件对0401工作面走向开挖进行模拟,通过监测不同岩层在逐步开挖过程中的下沉位移与应力变化过程,从而得出煤层逐步开挖后上覆岩层移动变形规律,进而为煤矿顶板岩层控制提供了相关依据。

According to geological data of 0401 working face in Fenxi Runtai Coal Mine Zhengming Coal Industry Corporation Ltd., UDEC numerical simulation was utilized to simulate the excavation of 0401 face by monitoring sinking displacement and stress changing process of different strata in excavation step by step to study the movement law of overlying strata in the process of Coal seam excavation. So that the movement and deformation law of overlying strata after gradual excavation of coal seam was obtained. And then provided relevant basis to coal mine roof rock strata control.
