Introduction

The failure of surrounding strata in the excavation faces is the root cause of some disasters, including roof caving, coal pillar instability, and water inrushes, during the extraction of coal resource. Identifying the abnormal phenomena and precursor information before rock failure forms an important theoretical foundations of achieving safety operation in coal mines. The infrared radiation (IR) on the surface of rock will change during loading process (Luong 1990; Freund et al. 2007; Gong 2013). By monitoring the IR, the deformation and failure characteristics of rock can be obtained (Sheinin and Blokhin 2012; Mineo and Pappalardo 2016; Sun et al. 2017; Fiorucci et al. 2018), reliable information for predicting rock failure precursors may be obtained, as well (Wu et al. 2015; Salami et al. 2017). In addition, the water content affects the IR characteristics during the failure of rock (Liu et al. 2010).

To quantitatively characterize the IR from the rock surface during...
