摘要： 司家营铁矿南区水文地质条件复杂，控水构造发育，含水层类型具有明显的分区特性，表现出了含水层类型的多样性。为获得司家营南区合适的水文地质参数，提出一种新思路，同时考虑含水层类型和求参方法，利用含水层识别获得含水层类型、补给条件、隔水边界、井筒储集等含水层性质，再结合相应的数学模型求参。研究表明，含水层识别在指导水文地质求参方面表现出了它的优越性，提高了求参精度，是一种指导正确求取水文地质参数的手段。
Abstract: The southern area of Sijiaying iron mine is of complex hydrogeological conditions, and the water-controlling structures well develop. The aquifer type has an obvious zonal feature, showing the diversity of aquifer type, which undoubtedly increases the difficulty to infer the hydrogeological parameters of aquifer. Hydrogeological parameters of aquifer have become an important basis for groundwater numerical simulation to forecast and evaluate groundwater resources. Therefore, to verify the obtaining parameters under complex hydrogeological conditions in southern area of Sijiaying iron mine, the authors put forward a new idea, considering the aquifer type and method of obtaining parameters, using aquifer identification of the aquifer type to obtain the aquifer type, recharge condition, impervious boundary,and well storage.Combined with the corresponding mathematical model, the parameters are determined. This research shows that the aquifer identification has the superiority in the aspect of guiding to the calculation of hydrogeological parameters. This method increases the calculation accuracy and it is an effective way to obtain the correct parameters
