The stress-strain state of test specimens of the new combined structure of support of a mine opening under loads is studied. The test specimens are compound modular elements of the designed earlier combined structure of support. Every single modular element is the triangular prism, consisting of a reinforced concrete slab and a steel grid made of tube web members. The slab and web members are grouped in a complete element while concreting the slab. The tension sensor’s method of experimental investigation is applied to the testing specimens. Tests of specimens are carried out under the load forced with cargoes. Loads are set in the ways that to simulate service conditions, counting the most adverse. Design features of the support and test specimens are shown. Particulars of the support and its elements, production technology, assemblies as well as the sizes are briefly described. The methodology of testing specimens, as well as the analysis of the outcomes, are presente.
