Abstract
The paper considers the capabilities of well-known laboratory facilities for hydraulic fracturing simulation in conditions of true triaxial loading. Test facilities which allow creating a crack in large cubic samples with an edge length of 200 mm or more are of great interest. In this case, it is possible to reduce the influence of edge effects from sample boundaries on the propagation path of the fracture. This review includes research results obtained from 10 different facilities located in major scientific centers
