The computation by the method of characteristics developed in this report locates propagating shocks and gives thier strengths precisely. It can provide the other details of the disturbance field with arbitrary accuracy through refinement of the finite difference mesh. Since the equations represent a medium without dissipation, their stabilization is a major difficulty. This stability problem has not yet been solved completely so that no numerical results of engineering usefulness are presented. The continuation and completion of the development of the present exact calculation method is recommended so that results of simpler, approximate methods for non-elastic media can be checked.

This Research Topic is Volume II of a series. The previous volume can be found here: Coal and Rock Dynamic Disasters: Advances of Physical and Numerical Simulation in Monitoring, Early Warning, and Prevention With the soaring growth of global population and socioeconomy, energy consumption and demand has been rapidly rising, and coal would still remain a fundamental energy source for a long time into the future. Seeking deep coal resources becomes an inevitable trend due to the depletion of shallow coal resources. Deep mining of coal resources promotes socioeconomic development, whereas bringing a variety of security challenges. In deep underground, there is a significant risk increase in coal and rock dynamic disasters (CRDDs), owing to the changes in physical and mechanical properties of coal and rock. In this regard, it is of great importance and necessity to prevent and control CRDDs effectively and efficiently.
