Abstract: The Deformation and fracture of loading coal or rock will produce acoustic emission (AE) and electromagnetic radiation (EMR) signals, so we can use the time and space characteristic of the precursory AE and EMR signals to warn coal and rock dynamic disaster induced by the fracture of a large range of coal or rock. It is the key of coal and rock dynamic disaster warning by AE and EMR signals effectively that how to integrate the time characteristics of AE and EMR signals with the damage process of coal and rock loading. In this article, we use the experimental system to test AE and EMR signals of coal or rock samples during deformation and fracture under uniaxial compression, and analyze the characteristics of EMR and AE signals pulse and energy in different loading stages by statistical method. It is shown that EMR and AE signals pulse and energy of loading coal or rock samples have obvious time characteristics, but are different；the value of AE and EMR signals of coal samples increase with the loading time and it reaches the maximum at the stage of the failure；the value of AE signals of rock samples reach the maximum at the stage of the failure while the value of EMR signals reach the maximum at the elastic-plastic stage.
