A signal simulation-based verification solution using UNI‑T UTG4000X series function/arbitrary waveform generators In deep coal mining operations, rock bursts and coal bump events remain critical threats to underground safety. Microseismic monitoring systems act as the “stethoscope” of the mine, detecting early warning signals before hazardous events occur. However, traditional on-site blasting tests are often costly, difficult to repeat, and may introduce additional safety risks during validation.
