There are many types of roadheaders: according to the working object, they are divided into ordinary machines and tunnel boring machines. Among them, a tunnel boring machine is a comprehensive equipment that uses machinery to crush rocks, remove mucking and support to perform continuous operations. According to the cutting process of the roadheader on the working surface, it is divided into full-section roadheaders and partial-section roadheaders; according to the working method, it is divided into open-type roadheaders and shield-type roadheaders. The former is well-known for its large-diameter full-section rock tunnel boring machine, which is a complete set of tunneling equipment integrating excavation, support and mucking.
