Abstract: Burst tendency has always been one of the hot issues in the research of rock burst. The national recommended standard GB/T 25217.3—2019 regulates the evaluation of the burst tendency of combined coal and rock specimens. The standard is implemented in 2020. Aiming at the content of this standard, this paper adopts the method of literature backtracking, focusing on the analysis of related Chinese literature. According to the survey, there are relatively few experimental studies on the burst tendency of coal-rock combinations, and there is not sufficient experimental data to support the residual energy index method which was proposed by this standard to assess the burst tendency of combined coal and rock specimens. Also, here still are some problems in sample collection, test piece assembly, and determination of residual energy index, which require further in-depth research. Overall, the classification criteria for the burst tendency are too broad and not accurate enough. In view of this, it is considered that the time for the implementation of this standard as a nationally recommended standard is still immature.
