Abstract

In order to improve the safety level of tailings transportation pipelines, a pipeline leakage detection and positioning method based on infrasound signals is proposed. The paper uses the quadratic cross correlation time delay estimation method to calculate the time difference between the two ends of the pipeline receiving the leakage signal, and combines the pipeline leakage location principle to locate the leakage point. The experimental results show that for a 2km tailings conveying pipeline, the positioning error of the leakage point at a 25mm leakage aperture is within ±50m, and the relative positioning error is maintained within 2.5%, effectively meeting the technical requirements of the engineering project.
