Abstract
After roadway excavation, the RADS forms, where complex physical and mechanical changes occur. As the most complex part, RADS is likely to form a dissipative structure. According to the previous research, the system is considerably stable at this time, and some small external disturbances are generally absorbed and have little effects on the system’s stability. But when external disturbances are great enough to damage its dissipative structure, the system will further self-organize and evolve and likely undergo rock bursts. In this chapter, we analyze the possibility of rock bursts in the RADS from the energy point of view, construct and numerically simulate the model for RADS’s dynamic pressure-type rock burst evolution, and study the characteristic evolution behaviors of the RADS based on the model by using the on-the field EM radiation data.
