Abstract
The problem is posed and calculations of stresses and weight coefficients in laminar roof at rock fracture are carried out. The calculations showed that increasing the energy of rock fracture reduces the influence of diffraction processes. The condition of brittle fracture of rock roof under dynamic loading is obtained.
