摘要
对地下水数值模拟软件Visual Modflow中水流边界条件的涵义和处理方法进行了分析和讨论,阐述了各类边界的运算机理及水文地质概念模型。用数值模拟进行矿井涌水量预测时,要在详细分析矿区水文地质条件的基础上,进行合理概化,防止因边界条件不合理而导致的预测误差。结合某矿实际生产中工作面涌水量预测实例对边界问题的处理加以说明,工程实例应用过程中效果较好,可为类似问题的解决提供一定的借鉴。
In this paper, the meaning and processing methods of the stream flow boundary conditions in the groundwater numerical simulation software Visual Modflow were analyzed and discussed, the operational mechanism of every boundary and the conceptual model of hydrogeology were elaborated. The paper pointed out that when numerical simulation was used in mine water inflow prediction, the regional hydrologic conditions should be generalized reasonably on the basis of a detailed analysis of the hydrologic conditions in the mining area so as to prevent from prediction error caused by unreasonable boundary conditions. Finally, explanation was made on the handling of the border issues according to the water inflow prediction in an actual production face in a mine, the application effect in the actual project is better, so it can provide certain referential significance for the solution of similar situations.
