Problems solved by technology

[0003] The roof (coal) of many coal mines and roadways is prone to roof fall during the excavation process. In order to prevent roof fall during the excavation construction process, the construction can only be carried out with a small cycle footage; The operation requires frequent switching between the two processes of excavation and anchoring, which seriously affects the construction efficiency and construction speed. This is why the monthly footage of many fully mechanized excavation working faces is less than 400m, and some even less than 300m. The main reason
This kind of construction speed not only affects the economic benefits of the enterprise, but also causes tension in the mining relationship of the coal mine, and even affects the continuity of the working face of the coal mine.
