Description

Technical Field

[0001] This utility model belongs to the field of testing equipment in mine backfilling, specifically relating to a pressure testing device for mine backfilling pipelines. Background Technology

[0002] In the field of mine backfilling, the slurry prepared at the surface backfilling station flows to the mined-out area through backfilling pipelines under the influence of gravity or external forces. The backfilling slurry contains crushed waste rock with a particle size of -12mm, a mass concentration of over 77%, poor fluidity, and lacks pressure monitoring instruments throughout the pipeline, making it impossible to determine the pressure distribution within the backfilling pipeline. During the backfilling process, operators rely on changes in slurry flow rate, concentration, and stirring level to comprehensively judge the slurry's fluidity and viscosity to ensure that backfilling does not clog the pipeline. Therefore, a pressure monitoring device for mine backfilling pipelines is of great significance for ensuring the safe and stable operation of backfilling production. Utility Model Content
