一、前 言 乙醇作为地下水示踪剂,首次在我国典型岩溶地区进行试验,已初步获得成功。 本文具体介绍了山东枣庄、河北峰峰、邯郸王风、广西合山等矿区用乙醇进行地下水示踪试验所取得的水文地质成果,如其中包括探索地下水的流速流向、地下水的迳流补给、含水层之间的水力联系、矿井突水水源、岩溶通道、断层导水性及其主要导水部位、帷幕注浆截流效果检验等方面的实际应用问题。 示踪试验是研究岩溶水运动的重要手段之一,而示踪效果则主要取决于示踪剂的选择等因素。
I. Introduction As the groundwater tracer, ethanol was first tested in typical karst areas in China and has achieved initial success. In this paper, the hydrogeological results obtained from experiments of groundwater tracing using ethanol such as Zaozhuang, Hebei Fengfeng, Handan Wangfeng and Guangxi Heshan are explored, including the exploration of the groundwater flow velocity, the groundwater recharge, The hydraulic connection between the layers, the mine water inrush, karst passage, fault water conductivity and its main part of water diversion, curtain grouting effect test and so on. Tracer test is one of the important methods to study the movement of karst water, while the tracer effect depends on the choice of tracer and other factors.
