Abstract

The authors describe operation of a laser deformograph within the integrated geodynamic monitoring system in Streltsov Ore Field. Capabilities and design features of the deformograph are discussed. The article demonstrates feasibility of highly accurate measurements of deformation field parameters in an operating mine. Specificity of natural oscillations of the Earth is defined, and deformation of rock mass depending on energy of a destruction source is evaluated.
