Description

technical field

[0001] The invention relates to the field of coal machinery, in particular to a roadheader. Background technique

[0002] With the rapid development of my country's national economy, energy consumption is increasing rapidly. Coal is the main energy source in my country, and its consumption is constantly increasing. my country's coal industry has also developed rapidly, and the coal machinery industry that is closely related to it has also been paid more and more attention.

[0003] Excavation and mining are important production links in coal mine production, and rapid excavation of coal mine roadways is a key technical measure for coal mines to ensure high and stable mine production. High-efficiency mechanized excavation and support technology is a necessary condition to ensure high production and high efficiency in mines, and it is also the development direction of roadway excavation technology.

[0004] In the prior art, there are mainly three tunneling su...
