Abstract
The method for estimation of the mean value and the mode of the property becomes important with increasing the depth growth of mining operations and the complexity degree of excavation sites, the growth of number of cases, when geological information volume representing the level of values of structural and physical-mechanical properties is insufficient. The reliability of estimates is achieved through the involvement of different characteristics of the studied property. The developed method is based on calculation of prediction estimates of the mean value and the mode, which allow providing the accuracy of the estimates with incomplete information, and when the type of the studied property distribution is unknown.
