Annotation:

The analysis of the operating conditions of development workings and behavior of the support in different geological conditions is done. Simulation results of preparatory workings fixed with arch and roof bolt support, using the finite element method are shown. The rational parameters of arch and roof bolt support of workings, both outside and in the zone of drift for maintaining their stable state are defined. Passport of fastening of development workings for geological and mining conditions of the mine «Komsomolets Donbassa» is recommended.
