Abstract
The current procedure for determining the boundaries of geological domains, the allocation of which is the mandatory element of digital geological modelling, does not entirely take into account the specifics of coal deposits. Without its improvement, it is impossible to increase the reliability of geological models used in the implementation of the “Industry 4.0ˮ strategy. A new method for analysis of geological data is supposed – the adjustment of the exploration grids method. It is to determine the corrections for values of measured parameters, the use of which eliminates the uncertainty of geological data interpretation. The correction values determined by the method of conditional measurements, which used at equalization geodetic networks. Corrections are considered as an indicator of the significance of measurement and interpolation errors which occurs in the vicinity of specific measurement points. The measured values of parameters are not corrected. Geological domains are the areas with close in values corrections, whose boundaries are corrections isolines. Separate single corrections of anomalous magnitude indicate the presence of extreme values parameters.

Summary
The estimate of mineral resources and reserves is an essential task for mining engineers. It is impossible to implement innovative technologies that meet the requirements of the “Industry 4.0ˮ industrial strategy [2]. The implementation of this strategy is envisaged by the Program of the development of the Russian coal industry for the period until the 2035 year, which considers the creation of the “Intellectual Quarryand the “Intellectual Mine. Obtaining the confidential estimates of the statistical parameters of the distributions and variograms of indicators in such conditions is impossible. The methodology improvement for the domaining of coal deposits, the quality of the allocation of which is a condition for obtaining confident models of deposits, is an essential task. Its solution is possible based on a new method for the analysis of geological data suggested by the authors – the method of adjustment of the exploration grids
