The tunnel roof support is a special steel material for coal mine support. Its shape is U-shaped, tunnel roof support is mainly used for mine roadway, secondary support of mine roadway, and support for mountain tunnels. As the main steel for manufacturing tunnel retractable metal supports, tunnel roof supports are widely used at home and abroad.
The tunnel roof support has the advantages of high initial support force, large support strength, easy installation, and not easy to deform. The tunnel roof support is therefore often used to manufacture tunnel retractable metal supports, used as mine roadway, secondary support of mine roadway, and mountain tunnel support and other uses. The use of tunnel roof supports improves the stability of the mine ventilation system.
The tunnel roof support is safe and reliable, which effectively reduces the occurrence of roofing and flank accidents and improves the stability of the mine ventilation system. The promotion and application research of the tunnel roof support has improved the safe production conditions of the mine and reduced production costs. Tunnel roof support is in line with the national policy of replacing steel with wood, and has better environmental protection and social and economic benefits. The tunnel roof supports of our company are not only complete, but also passed the relevant quality system certification of the country and industry. It is our duty and desire to serve the coal mine producers and builders wholeheartedly.
