Abstract. Intent: basing on the instrumental survey measurement, to determine rate of tensile strain displacements in the rock mass.
Results. Results of the instrumental surveying monitoring of the rock mass and surface displacements were generalized, and on their basis, rate of deformation was determined. Interdependence between the rate of the deformation displacements, rate of the mine face drivage, depth of the mining operations and height of zone with the rock foliation was specified.
Scientific novelty. It is for the first time when, on the basis of instrumental observations, rate of the tensile strain displacement in the rocks with varying degrees of lithification was defined. Height of zone with the rock foliation in the undermined mass was determined on the basis of the established interdependence between the rate of deformations.
Practical significance. The obtained data on the rate of deformation displacement in the undermined rock mass makes possible to control rock pressure and to improve efficiency of mining operations and their safety.
Keywords: underground mining operations, rate of deformation, dynamic trough, surveying monitoring of displacement.
