复杂水文地质条件下地下水数值模型的应用

Application of Groundwater Numerical Model under Complex Hydrogeological Condition

井下富水矿床的开采中,地下水流场变化是制约矿山安全建设和生产的重要因素,如何准确判断地下水流场变化情况对矿山安全开采具有重大意义。结合白象山矿区水文资料,以黄马青组杂色粉细砂岩基岩裂隙含水系统作为研究对象,建立地下水水文数值模型,利用数值模型对地下水变化情况进行分析。分析结果表明,数值模型能够较为准确地描述矿山地下水流场变化情况,该方法可作为保障矿山安全建设的重要依据。

For the exploitation of the underground rich water deposit,the variation of groundwater flow field has become the important factor of restricting the safe construction and production of mine. How to accurately judge the variation of groundwater flow field is the great significance to the mine safety production. Combined with hydrological data of this mining area,and based on the bedrock fissure water system of the Huangmaqing group mixed silty sand rock,the numerical model of groundwater hydrology was established to analyze the variation of groundwater. The analysis results showed that the numerical model can describe the variation accurately. This method can be used as the important basis to ensure the safety of mine construction.
