Abstract
The manifestations of rock pressure are evaluated according to the results of rock deformation studies in the workings of faces No. 905, 909, 910 in the Polysaevsky-1 formation. The results of measurements of vertical convergence between the ground reapers and anchor rods in the roof of the diagonal furnaces of faces No. 909 and 910 allow us to talk about the uncharacteristic shift of the rock massif. This can be confirmed by the results of the previously measured stresses in the coal massif, carried out with high-modulus photoelastic sensors, installed in the ventilation drift of the working face No. 905.
