	The process and the test results of the solid rock loosening by use of the fixed undercutting bolt are described. The tests were carried out within the RODEST project, OPUS 10 competition No. 2015/19/B/ST10/02817, financed by the National Science Centre, where a series of numerical modelling as well as laboratory and in-situ tests were planned. The test stand equipment as well as methodology for conducting the in-situ tests are presented. The tests were conducted in four mines. In each mine tens of solid rock loosening tests were conducted, during which the process parameters were recorded. Additionally, the loosened area outline in each successful test was recreated using 3D scanner. Data collected during in-situ tests as well as strength properties of the tested rocks enabled analysing the loosening process (forces, ranges) in relation to the rock type.

Analysis of the process of loosening the rocks with different strength properties using the undercutting bolts
