TITAN-260
It is designed for mechanization of mining and loading of rock mass during excavations of arch, trapezoidal and rectangular shapes, with cross-section from 15.5 to 31 m2 in sinking, with inclination angle of ±12 degrees on coal, rock and mixed face, with maximum uniaxial compressive strength of rocks up to 120 MPa (f=8), and abrasiveness up to 18 mg, in mines hazardous by gas and dust, and the content of rocks with σczh>=120 MPa should not exceed 20% of the face area with total rock cutting not more than 75%. The angle of inclination of the excavation should be within ±18 degrees.
