Non-invasive and Real-time Monitoring of Tailings Slurry Density in Transmission Pipeline Using the Electrical Resistance Tomography (ERT) Method
Confirmation seminar presented by Yue Xiong
As a byproduct of ore processing, tailings are commonly mixed with water to form slurry, which is then transported through industrial pipelines to tailings storage facilities for centralized disposal. To prevent pipe blockages, nuclear-based tomography has been widely used to monitor slurry density distribution; however, it poses significant radiation risks, highlighting the need for safer alternatives.
Electrical Resistance Tomography (ERT), a non-radiative, real-time method for assessing the electrical characteristics of fluids in pipelines, presents a promising solution. Nevertheless, ERT’s effectiveness in monitoring tailings slurry in large-scale industrial pipelines has yet to be validated, and methods for accurately correlating the electrical characteristics of tailings slurry with its density require further refinement. This study seeks to employ ERT to reconstruct the density distribution of tailings slurry in pipelines and conduct field validation. Expected outcomes include demonstrating ERT’s capability in monitoring tailings slurry within pipelines, reducing dependence on nuclear-based technologies.
