Substantiation of roof and pillar stability monitoring in mines with the help of information criterion

The ways are considered for raising reliability of seismic monitoring over pillar, superincumbent strata, and roof state. It is shown that the probability of correct recognition of the rock mass state can be risen by the increase in number of informative parameters and calculation of their derivatives. The minimum of the informative parameters is calculated on the basis of information criteria and results of in-situ observations. To make a decision on the state of rock mass, the Bayes criterion and the methods of multiparameter pattern recognition are used.
