摘要
介绍了大型三维固流耦合模拟试验台(3 m×2 m×2 m)、相应的辅助设备及其功能,并对太原市东山煤矿承压水上采煤进行了模拟研究,通过实验过程中采集到的大量数据、拍摄的照片、微型监测仪的录象,分析了开采过程中采场顶底板的变形及其破坏过程、应力及其水位的变化规律、断层对矿井突水的影响等。为进一步实施矿井突水实时监测预报提供必要的理论依据,为控制采场及采场内水、瓦斯的流动、扩散提供切实可行的理论依据与实施方法。
The paper introduces the 3-D solid-liquid coupling simulation test bed （3 m×2 m×2 m） , the corresponding assistant equipment and its function. The simulation study on mining above artesian water of Taiyuan Dongshan Colliery was made. A great deal of data, photos and video information were obtained. The wall rock distortion and breakage process, the change law of stress and water pressure, the faultage influence on the water inrush and the change law of water pressure in the mining were analyzed particularly, which may provide essential theory and effective methods for the forecast of mining water inrush and controlling water and gas flow in the stope.
