Some energy relations of rock fracture at different structural levels

There exists a complex structural hierarchy in rock mass. Intimate connection between time and spatial scales exists at each structural level. Such a connection lies in the fact that the time before the rock fracture at each structural level is proportional to the size of geoblock at that level. In the present study, the principles of constant work density, constant energy flux, and equal power are found on a basis of such connection. They can serve as a tool for the analysis of deformation and fracture of rock mass at different levels.
