MINING MACHINE Russian patent published in 2023 - IPC E21C27/24 E21D19/00 E21D23/00 

FIELD: mining engineering.

SUBSTANCE: invention relates to the field of mining engineering and can be used in the construction of mining machines. Mining machine includes running gear, conveyor, arrow-shaped executive body with cutting head and drilling device. Said drilling device is mounted on the arrow-shaped executive body and contains a frame made with the possibility of extension in the direction of the bottom. On the retractable part of the frame, a positioner is pivotally fixed with the possibility of extension to the face chest. The positioner is made with beams retractable transversely to the working axis, retractable on the sides of the positioner with the possibility of adjusting the position of their end parts relative to the working axis. On the end parts of the beams with the possibility of lateral deviations, drilling rigs are pivotally fixed by means of hydraulic cylinders.

EFFECT: reducing the time for technological operations in the drilling process, increasing the possibilities of drilling and improving the safety of work.
