An artificial intervention based method for determining the runoff zone of an underground aquifer

By deploying monitoring wells between the goaf and the spring outlet, and combining them with flow velocity and direction meters and pumping tests, changes in flow velocity and direction can be monitored in real time. This solves the problem that existing technologies cannot accurately capture the flow channels of groundwater pollutants, and enables efficient decision-making for blocking polluted water.

AI Technical Summary

Technical Problem

Existing technologies cannot accurately capture the dynamic dominant runoff channels of groundwater pollutants, leading to delays in pollution containment decisions.

Method used

By deploying multiple monitoring wells between the goaf and the spring outlet, and combining flow velocity and direction meters with pumping tests, changes in flow velocity and direction can be monitored in real time to identify the main runoff zone and potential pollution migration paths.

Benefits of technology

It enables high-precision identification and dynamic monitoring of underground runoff channels, guides the effective blocking of polluted water, avoids misjudgment of static data, and improves treatment efficiency and effectiveness.

Abstract

本发明公开了一种基于人工干预的地下含水层径流带测定方法，主要涉及地下水检测技术领域。包括确定采空区和泉排泄口的空间位置；在采空区内布设1处试验井，在试验井和泉排泄口之间布设不少于6个监测孔；连续记录各个所述监测孔内72小时天然流场下的流速、流向作为背景值；对试验井进行多阶段抽水试验，同步采集各监测孔的水位降深值及流速矢量变化；将流速矢量变化与背景值对比分析，综合水位降深值，输出主径流带及轴线延伸方向，径流带与泉水区的空间关系。本发明的有益效果在于：通过"点尺度流速监测"与"区域尺度抽水扰动"的联动，实现了从局部动态监测到区域径流场识别的尺度转换，实现对径流通道精确捕获。
