Abstract

The invention discloses a pipeline blocking monitoring device and a pipeline blocking monitoring method for a paste filled pipeline. The pipeline blocking monitoring device comprises a monitoring pipeline, a resistivity testing device and an insulating gasket, wherein the monitoring pipeline is arranged on the paste filled pipeline; the resistivity testing device is arranged inside a circular groove in the inner wall of the monitoring pipeline. The resistivity of paste in different positions in the paste filled pipeline can be tested, if the pipeline is blocked, the resistivity of paste in front of and behind a blocking position of the monitoring pipeline is greatly different, and then precise positioning on the blocking position can be achieved. By adopting the pipeline blocking monitoring device and the pipeline blocking monitoring method, automatic monitoring on the paste filled pipeline is achieved; the pipeline blocking monitoring device is simple in structure, easy to disassemble and convenient to operate, multiple monitoring pipelines can be arranged on a paste conveying pipeline, and only one resistivity testing device needs to be connected, so that the cost is lowered.

Description

technical field [0001] The invention relates to a monitoring device and method for plugging of paste filling pipelines, in particular to a device and method for monitoring plugging of long-distance paste filling pipelines in mine filling mining, and belongs to the technical field of pipeline transportation of paste filling materials. Background technique [0002] my country's "three under" coal pressure is huge. In order to effectively exploit the "three under" coal resources and extend the service life of the mine, paste filling mining is one of the effective methods to liberate the "three under" coal pressure. The paste is filled on the ground and the raw materials are mixed, and then rely on pipelines to realize efficient and continuous transportation to the goaf. During the transportation process, debris entering the pipeline, slurry segregation and sedimentation, insufficient pumping pressure and other reasons are likely to cause pipeline blockage. Pipe plugging not on...
