本文采用室内相似材料模拟试验的方法,用两种不同的开挖方案模拟采动过程中地下水流场的变化情况,通过对水位变化数据分析,运用surfer软件制作出三维流场时空变化图,直观再现了采动条件下地下水水位降深和影响边界的变化情况。通过Excel数据分析功能,分别分析了两种开采模式下水位降深和影响半径之间的变化规律、影响半径和采动距离之间的变化规律,并且均拟合出了一定条件下的曲线方程。通过对所有数据及结论的对比分析,确定出最优的开采方案。本次研究对以后的采煤保水工作和防治突涌水事故均具有重要的指导意义。
In this paper, indoor similar materials simulation test method, using two different excavation program to simulate the groundwater flow during mining process changes, through the water level changes in data analysis, the use of surfer software to produce three-dimensional flow field of temporal and spatial changes in the map, intuitive Reappearance of mining under the conditions of groundwater depth and impact of border changes. Through the Excel data analysis function, the variation regularity of water depth and the influence radius between two mining modes are analyzed, and the variation law between the influence radius and mining distance is analyzed respectively. And the curve equation under certain conditions is fitted . Through all the data and conclusions of the comparative analysis to determine the optimal mining program. This study has important guiding significance for the future coal mining water conservancy work and the prevention of sudden water influx.
