Paper Title:
Study on Infrared Characteristics in the Progressive Failure of Bolted Rocks under Uniaxial Compression
  Abstract

For the demands of thermal infrared (TIR) radiation change regularity for TIR radiation detection experiments of interaction between bolt and rock, TIR image information extracting and quantitative analysis of bolts action zones were carried out. The IR isothermal fringes of the bolted bocks were obtained through thermal infrared image subtraction of bolted bocks and data fitting. The interaction ranges between bolts and rock were obtained and the bolted ranges of lateral directions were determined. The quantitative treatment methods were applied to analyze infrared images of bolted roadway also. The common acting zones of several bolts in the surrounding rocks are determined. The theoretical guides have been provided for the bolt supporting parameters design of spacing interval and array pitch.
