Square Arches are used in mining for face installation and for bolting roadways in the case of encountering complex and difficult geological conditions.
The idea for designing these arches was created thanks to cooperation with the mining industry and is a response to the requirements of a rectangular coal mine to obtain a large width of the excavation.
