PL PLPriority: Application announced: May 30, 1973 Patent description was published: February 14, 1975 74715 KI. 5d, 5/00 MKP E21f 5/00 C2YTELNIA Inventors: Tadeusz Dybel, Zygmunt Gerlach, Marian Itozdrój, Zbigniew Klonowski Authorized by a temporary patent: "Miechowice" Coal Mine, Bytom (Poland) The invention is a method of liquidation of the rock mass present in the vicinity of mining excavations. Currently, in the case of an increase in the damage in the vicinity of mining excavations, the most commonly used method of checking the discharging of the rock mass energy is to cause sinking by firing a certain amount of explosive material. The disadvantage of this method of de-stressing the rock mass is that the firing of even very large explosives charges resulted in disproportionately low impact of dynamic forces on the mountain compared to the forces of tapping, dHaitego, yeah The rocking and jkarielawiaintie of the magnitude of the stresses during firing did not provoke a tipping. The object of the invention is to provide a method of disturbing the existing balance of forces in a pre-loaded rock mass, which would cause sagging. This aim was achieved by developing a method, the essence of which is that the energy of the rock mass is discharged during its growth to a critical value, which is discharged by known methods using shock shooting. Stiafti toprezen ^ ónqitwoxiU after the completion of the method of settling up became matfla ^ pairatiira seistoiczina. PL PL
