The full-section roadheader for coal mine rock roadways is a roadway excavation equipment specially designed for coal mine rock roadway engineering, and the complete machine has a coal mine safety certificate. In 2021, the world's first main-beam center-replacement walking-type coal mine roadheader was developed by our company. It pioneered a fully mechanized excavation method in the field of coal mine roadway construction, leading the technological transformation of coal mine roadway construction.
In relatively intact surrounding rock with a certain degree of self-stability, especially in rock strata with a rock firmness coefficient greater than f7, the construction efficiency can be increased by 4-6 times compared with boom-type roadheaders and the drill-and-blast method.
