Among the mechanical excavators, roadheaders are mechanical miners which have been extensively used in tunneling, mining and civil industries. Performance prediction is an important issue for successful roadheader application and generally deals with machine selection, production rate and bit consumption.
Roadheaders were initially utilized in coal mining applications. The first use of a roadheader in a civil engineering project was the construction of the Melbourne Underground Rail Loop in the 1970s, where the machines enabled around 80% of excavation to be performed mechanically.
