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

FIELD: mining.

SUBSTANCE: invention relates to the mining industry and can be used in underground mine conditions for drilling technological holes with mining machines in the process of working and mining. The mining combine includes a running gear, a conveyor, on the frame of which two executive bodies with drives are mounted, an upper fender and a berm body. Also, the mining combine contains a drilling device fixed on the non-rotating parts of the combine by means of hydraulic cylinders with the possibility of spreading, holding and returning during the movement of the combine. The drilling device comprises a cover and guides with drilling carriages equipped with sliders. The overlap includes a stepped horizontal surface and a vertical wall rigidly connected to it with arc-shaped guides, with which the guides are connected with drilling carriages by means of sliders installed in the arc-shaped guides of the overlap, with restriction from longitudinal, relative to the movement of the combine, movements, and with the possibility of moving along the arc-shaped guides in the transverse, relative to the movement of the combine, direction. The central step of the horizontal surface of the ceiling is equipped with at least three studded shoes spaced along the edges, has a width and protrudes above the side ledges of the horizontal surface to a height of not more than 180 mm. The width of the central step of the horizontal surface of the ceiling is less than the length of the upper fender.

EFFECT: proposed design of the mining machine provides guaranteed adhesion of the upper surface of the floor of the drilling device with the roof of the mine working for drilling holes in the mine working vertically into the roof and/or at an angle to it while the machine is moving to the face with the formation of an oval-arched mine working, and also facilitates access to equipment located in the internal volumes of the combine for maintenance and repair directly at the workplace in cramped working conditions.
