Roadheader – A comprehensive review - ScienceDirect

Jan 01, 2020 Jan 01, 2020 The roadheader is a machine for excavating rock in mining and civil construction projects. It is a hybrid machine, with better manoeuvrability than that of tunnel boring machines. It can cut rocks even up to 160 MPa, if laminated or fractured, in different tunnel profiles and adapts easily to changing operational conditions

Industry • The history of roadheaders

Jun 01, 2019 A roadheader is a machine intended for the excavation of underground headings, i.e. a machine which performs several functions within that process. A heading is an excavation characterised by considerable length in relation to its cross-section. These include various roadways, adits, crosscuts, drifts, inclines (sometimes shafts and staple pits
