A roadheader is an excavating machine used in underground mining and tunneling to continuously cut rock and other materials without explosives, allowing for precise tunnel shapes and sizes. Key components include a boom-mounted cutting head with durable picks (e.g., tungsten carbide) that rotates to break rock. The boom maneuvers the cutting head, while a loading device, often an integrated conveyor system, gathers and transports the excavated material (muck) to the rear of the machine. The enti

Two heavy-duty Sandvik MT720 tunneling roadheaders are successfully in operation since February, used in a construction project, a 3.5 kilometer metro line extension in South Korea. Due to the restrictions on drilling and blasting in urban areas, ICUTROC technology supports the roadheaders to tackle challenging geological conditions (exceeding 150 MPa uniaxial compressive strength (UCS) and CAI abrasivity of more than 3) which are not typical for mechanical cutting applications. Additionally, Sa
