DK-1 is designed for mechanized cutting of coal, salt and oil shale seams with an incidence angle of up to 20°. This machine can be used in mines where the ambient air content of methane, coal ash, hydrogen sulfide, carbon dioxide, etc. does not exceed the safety content specified in the coal, salt or oil shale Mine Safety Regulations. This machine is used for the mining of complex seams. It can be used to cut the bottom groove in the working face with a height above 0.5 meters. Suitable for the working surface seam strength rock limit for uniaxial compression, no more 110 MPa. The electrical parts of the machine have certain explosion-proof performance.
Key Features:
