在前期工作的基础上 ,基于新的 (补充 )采集的地下水化学样品的分析数据 ,以 WATEQ4F模型 1 为基础 ,应用本次研究中开发的耦合的 Monte Carlo— WATEQ4F模型 ,对平顶山矿区地下水系统中水 -岩反应状态进行了随机水文地球化学模拟和评价。结果表明 :随机水文地球化学模拟方法具有很好的实用性和应用前景 ;在模拟研究区内地下水相对于方解石、白云石、石英过饱和 ,相对于石膏未饱和 ,而与玉髓处于平衡状态。这些结果为该区地下水 (子 )系统的划分、岩溶发育规律研究和地下水资源评价提供了进一步的依据。
On the basis of previous work, based on the analysis data of groundwater chemical samples collected from new (supplement), based on the WATEQ4F model 1, the coupled Monte Carlo-WATEQ4F model developed in this study was used to analyze the groundwater system in Pingdingshan mining area The hydrogeochemical simulation and evaluation of water-rock reaction status were carried out. The results show that the stochastic hydrogeochemistry simulation method has good practicability and application prospect. The groundwater is supersaturated with calcite, dolomite and quartz in the simulated study area, and is not saturated with gypsum, but is in equilibrium with chalcedony. These results provide a further basis for the division of groundwater (sub) system, the study on the law of karst development and the evaluation of groundwater resources in this area.
