Coal bursts occurring in steeply inclined coal seams (SICSs) are increasingly severe.
To solve this problem, a mechanical model for the distribution of static stress on coal-rock masses along panels and the distribution of dynamic load induced by the breakage of thick and hard roofs with propagation distance was established.
The stress characteristics after a superposition of dynamic and static loads on the roof and floor roadways (Rr and Rf) were determined.
In addition, precursory information characteristics and index sensitivities of four indices for dynamic loads and the CT index for static loads based on seismic tomography were separately analyzed.
The monitoring and warning indices for SICSs and flat seams were compared.
The results showed that the static stress of Rr was significantly higher than that of Rf, which provided a basis for the stress-triggering coal burst behaviors.
Three indices for dynamic loads and seismic tomography results exhibited remarkable precursory information and high sensitivity.
However, the performance of lack of shock index is poor.
The continuous anomaly and the contradiction of indices at Rr and Rf can be considered as precursory information for predicting coal bursts.
