Boom-type roadheader R-100 SM

The R-100 SM shearer is intended for mechanised mining of minerals (hard coal) and/or waste rock, characterised by the unit compression strength up to 60 MPa. The basis for the R-100 SM model was the AM-50z-w shearer, whose major subassemblies, such as the frame, the turntable and the cutting drum have been used. Range of seam heights: longitudinal (downwards/upwards): ± 8 transverse: 5° The shearer can be used in underground mining plants in methane hazard-free and methane hazard fields in headings rated as “a”, “b”, “c” methane hazard and “A” or “B” coal dust explosion hazard, on condition that is de-energised at the maximum increase in methane concentration up to 2%.
