Abstract: Cutting depth and spacing are two important parameters for the efficiency of a roadheader in mining operation. In this study, the case of a roadheader excavating a coal gallery is taken into account. Based on the explicit finite element analysis (FEA), the minimum cutting specific energy (SE) was obtained by the series of numerical simulations.
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.

EBH300(A) transversal Axis roadheader for 130MPa rock roadway with 300kW cutting power. Applications: For the tunneling of rock and semi-rock roadway, also used in the tunneling of highway, railway, and water conservancy projects.
A major strength of roadheaders for mining is the fact that also develops and manufactures productive and durable cutting tools for the machines. Better tools and less frequent tool changes translates to direct improvements in productivity, cost-per-tonne efficiency, maintenance costs and energy efficiency.
Coal mining | Britannica.com. Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth.
The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process.
