Paper Title:
Experimental Study on Infrared Radiation Changes with the Fracture and Progressive Failure of the Submarine Soft Rock Roadway
  Abstract

Based on the submarine soft rock supporting engineering in Beizao Mine, the physical model tests of four kinds of supports were carried out including high strength (HS) roadway without support, HS soft rock roadway with U-shape steel support (U-S-S-S), low strength (LS) roadway with bolt support (B-S), and LS roadway with U-S-S. The thermal infrared (TIR) changes with the fracture and damage of roadway are investigated. It is discovered that the TIR radiation is the stronger in the stress concentrated area, strong friction and interaction range between U-steel support and roadway than that in the stress relaxed area and week friction. The TIR temperature (TIRT) of the fracture increased higher and changed rapidly than other parts. The TIR radiation of soft rock is influenced with seawater. The TIR-anomaly appears at the stress concentrated area, interaction ranges and fractures. The TIR omens occur when load is 65%~90% of the peak load.
