A method of artificial falling of hard-caving covering during mining of minerals from the underground bed-rock by a mechanized complex is applied in the mining industry, especially can be used for the forced falling of the of hard-caving covering during mining of minerals, coal especially, in case of difficult geologic conditions. A method of artificial falling of hard-caving covering during mining of minerals from the underground bed-rock by a mechanized complex is including the mounting of the mechanized complex at a face, its adjusting within considering the concrete geologic conditions, operating the extraction by means of a combine, transporting of broken minerals along the face, moving of support setting sections and of transporting appliance, cleaning the remnant of minerals, if any, demounting of the mechanized complex after finishing the working and introducing, in case of hard-caving covering, the support setting sections in the working regime of vibration with a frequency of ( 0.05...0.10 ) Hz and an amplitude (10...50 ) mm by using mechanized hydraulic support settings by periodical change of pressure in the hydraulic system. The technical result is to be the increase of safety of the face working and efficiency of mining the bed-rock minerals.
