帷幕注浆是现阶段矿山治水工程的主要技术,但帷幕注浆工程竣工后,矿区已有地下水位观测网往往不能准确反映地下水流场特征。为此,运用数值模拟方法研究丰水年和枯水年地下水流场的变化特征,以确定地下水位变化大的危险区域;之后从能有效观测地下水流场的形态出发,采用克里格方法获得应加密的水位观测区域和应封填的水位观测孔。在综合上述研究成果的基础上,提出地下水位观测网的空间结构(观测网的密度和位置)的优化方案。
Curtain grouting is the main technique of mine water treatment project at the present stage. However, after the curtain grouting project is completed, the observation network of groundwater level in the mine area often can not accurately reflect the characteristics of groundwater flow field. Therefore, numerical simulation is used to study the variation characteristics of groundwater flow in wet years and dry years in order to determine the dangerous area where the groundwater level changes greatly. After that, the kriging method can be used to obtain the groundwater flow field effectively. Water level observation area to be encrypted and water level observation hole to be filled. Based on the above research results, the optimization scheme of the spatial structure (the density and position of the observation network) of the groundwater level observation network is proposed.
