METHOD OF MINE WORKING Russian patent published in 2017 - IPC E21C27/12 E21D9/11 

FIELD: mining engineering.

SUBSTANCE: method consists of multipoint impact on the free surface of the face by the executive bodies driven by external energy sources, giving the central executive body the direction of movement of the combine with the subsequent activation of the peripheral executive bodies and their movement along the trajectory of the epicycloid. At the same time, a shock-shearing effect of a rock-destroying tool by means of generators of mechanical impulses is carried out on the free face by applying prolonged shock loads with a successive step-by-step displacement along the entire surface of the face section.

EFFECT: expanding the use of mechanical impact and force to destroy strong rocks, the possibility of changing the direction of mining workings, especially in difficult mining and geological conditions, reducing energy intensity, improving the working conditions of maintenance personnel.
