Abstract
A physical model test system for simulating strong mine tremors based on joint monitoring of MS and AE and a test method thereof, comprising: positioning and drilling a circular hole in a load plate according to design positions of all-fiber MS and AE sensors; mounting limiting rings concentric with the circular holes outside the load plates; bonding seismic isolation antifriction plates on inner walls of the load plates; manufacturing model body through layered compaction method to a height reaching one of the circular holes; inserting wave conducting rod into the limiting ring and the circular hole sequentially to a specified depth of the model body; filling with analogue materials and compacting; detaching the limiting rings after the model body is stably loaded, connecting the all-fiber MS sensors to exposed portion of the wave conducting rod, and bonding the AE sensors to outer sidewalls of the wave conducting rods.
