Abstract

The article deals with the method for effective evaluation of stress state and rock burst hazard of sections of coal seams by the predicted output of drilling fines. The suggested engineer solution, i.e. the program modulus «Prediction» allows to represent the formation of the support pressure zone in the marginal part of the seam (or in a mine working) and to control the potential pattern of rock burst hazard manifestation in a mine working under various geological and mining conditions.
