Abstract
The paper presents a proposal for a method of rock-burst risk estimation based upon an analysis of the non-homogeneity degree of rock cracking processes. In periods preceding moments of tremors there are tendencies towards enlargement of crack sizes causing increases in the non-homogeneity degree. It is known that rock cracking is represented in the form of a seismoacoustic emission, which can be observed (registered). The non-homogeneity degree of the cracking process can be estimated on the basis of the statistical analysis of the registered seismoacoustic emission stream. It is known from experience that the registered emission constitutes nonstationary and non-homogeneous stream of events. Information about energies (extents) of processes and time intervals between effects is necessary for its complete description. The paper presents appropriate models of measures describing the non-homogeneity degree of the cracking process. These measures treated as indicative functions enable a qualitative connection between the non-homogeneity degree discussed and the rock-burst risk condition. The findings have been illustrated with examples of behaviour of these measures estimated on the basis of the registered seismoacoustic emission stream in the G-22/4ZG "Rudna" Branch.
