Study on Seepage Velocity Detection Technology of Tailing Pond
Percolation is the flow of fluid through porous media.When the rainfall is too large or there is a large water source near the tailings,seepage will easily form,which makes the tailings pond in danger of dam break.In order to be able to detect real velocity of tailings seepage,and do not change seepage flow state during seepage tests,a kind of seepage detector based on the principle of heat temperature difference is designed.When the fluid flows through the thermoblock surface,it will take away heat,and this form of heat will continue to transfer to the downstream of the outer wall temperature sensor.The temperature sensor encapsulated in the interior col-lects the temperature,and the temperature difference signal collected by the upstream and downstream temperature sensors is converted into electrical signal through the acquisition circuit and sent to MCU for data processing.Through the corresponding numerical conver-sion,the current seepage flow velocity can be observed on Ali cloud and the host computer.The detector device is small in size,easy to install,no need to take over more external equipment,can be buried in underground rock and soil for long-term real-time monitoring,and will not cause pollution to the surrounding environment.
