Geomechanical basis of rock mass hydraulic fracturing
Authors:
Abstract
The theoretical basis for determining the fluid pressure required for hydraulic fracturing of a rock massif of block structure is outlined. The criterion of strength of such massif at volumetric character of deformation development in anisotropic field of gravitational-tectonic stresses is grounded. The results of Tyrnyauz experimental hydraulic fracturing of hot granites at a depth of about 4 km, as well as a comparison of calculated data with the results of hydraulic fracturing conducted by the Los Alamos laboratory of the United States.
