Full-section excavator for coal mine
The full-face excavator used in coal mine is a roadway excavation equipment specially designed for rock roadway engineering in coal mine. The machine possess the safety certification of approval for coal mining products for safe excavation in the coal lane. In the relatively complete surrounding rocks with a certain degree of self-stability, especially in the rock stratum whose rock robustness coefficient is greater than f7, compared with cantilever excavator and borehole-blasting method, the construction efficiency can be increased 4-6 times. In the field of coal mine roadway construction, it has created a fully mechanized excavation method, which will lead the technical transformation of coal mine roadway construction.
