| 摘 要： | 为探究水文地质的影响因素,并为后续的防治工作提供清晰可用的数据来源,在分析影响矿井水文地质的原因的基础上,提出了一种新的MODFLOW-USG(非结构网格)模拟方法。以我国陕西某褐煤矿井地质为例,对MODFLOW-USG的详细建模过程和优势进行了分析,证明了MODFLOW-USG的可行性和有效性。分析认为,利用MODFLOW-USG可以处理许多复杂的水文地质特征,如不连续性(地质断层、矿井开口等)、陡峭和不平坦的斜坡,或夹出地层,处理方法可以为相关行业的水文地质灾害防治提供一定借鉴。

| Abstract: | In order to explore the influencing factors of hydrogeology and provide useful data sources for the follow-up prevention and control work,a new MODFLOW-USG(unstructured grid)simulation method was proposed based on the analysis of the reasons affecting the mine hydrogeology.Taking the geological conditions of a coal mine in Shaanxi Province as an example,the detailed modeling process and advantages of MODFLOW-USG were analyzed,and the feasibility and effectiveness of MODFLOW-USG were proved.According to the analysis,MODFLOW-USG can be used to deal with many complex hydrogeological features,such as discontinuity(geological fault,mine shaft,etc.),steep and uneven slope,or sandwiched out stratum,which can provide some reference for the prevention and control of hydrogeological disasters in related industries. |
