含水层水力联系温度-渗流耦合模型研究

Study on the Temperature-seepage Coupling Model of Hydraulic Connection in Aquifers

为研究含水层水力联系预防矿井水害,建立温度场-渗流场耦合数值模拟模型,模拟研究不同含水层水力联系状态、不同回采距离条件下渗流场与温度场的变化规律。研究得出:不同水力联系方向对温度场的作用规律不同,工作面附近温度场的变化能够用来判断顶板含水层水力联系情况,为研究含水层水力联系提供了一种新的研究思路。

To study the hydraulic connection of aquifers and prevent mine water hazards,a temperature field-seepage field coupling numerical simulation model is established to simulate the changes law in seepage and temperature fields under different hydraulic connection states of aquifers and different conditions of mining distances.The research showed that different hydraulic connection directions have different effect laws on the temperature field,and changes in the temperature field near the working face can be used to determine the hydraulic connection condition of the roof aquifer,providing a new research idea for studying the hydraulic connection of the aquifer.
