Annotation:

Method of construction of vertical workings by drilling them is one of the most promising methods. Improvement of its competitiveness requires an analysis of existing technical and technological parameters for their further improvement. The statistical analysis of the quality of wells drilled in Krasnoarmeysk, Dolzhano-Rovenetsk, Donetsk-Makeevka and Petropavlovsk mining areas is carried out. Probabilistic and statistical prediction models are designed. Autocorrelation functions were obtained for each well, allowing assess the quality of the walls of excavations, which are being built.
