The Coal-Rock Triaxial Stress Pore-Seepage-Acoustic-Electric Integrated Parameter Testing System is an advanced experimental device used to study the physical and mechanical properties of coal and rock under complex stress conditions. It can simulate the stress environment of coal and rock in actual engineering, providing important experimental data and theoretical support for coal mine safety, petroleum engineering, geotechnical engineering, and other fields. The system has multiple functions, including mechanical parameter testing, porosity and permeability determination, acoustic wave characteristic measurement, electrical parameter measurement, and acoustic emission monitoring.
