[0002] To address the "three down, one up" coal pressure issues and the environmental pollution caused by waste rock discharge, paste filling mining technology has made significant progress. As part of the green coal mining technology system, paste filling technology aims to address the "three down, one up" coal pressure issues, protect the mining environment, increase coal resource recovery, and extend the service life of the mine.

[0003] Currently, the paste delivery method used in underground coal mines primarily relies on a filling pump and its own weight, with the paste being transported to a designated filling area underground via a filling pipeline. However, in actual operation, due to the high pressure within the pipeline and the gradual decline in equipment sealing performance over time, coupled with improper cleaning and maintenance, the universal joints in the filling pipeline often infiltrate and solidify due to the high-pressure paste, causing rust on the moving parts, leading to blockages and even jamming. Unfortunately, existing technical means lack specialized tool support for the disassembly and repair of universal joints, which not only makes the repair process time-consuming and lengthy, but also greatly increases the labor intensity of operators.
