The article considers the results of observations of mountain pressure in combined drifts No.157 and No.161 of Stepnaya Mine that belongs to VAT Pavlogradugol. Methodology of supervisions is described and a chart of the observant station is brought. Mathematical treatment of results of measuring is executed, with dividing of vertical convergence into constituents. The charts of development of convergence during driving of production face are built.
