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
