The steel arch support solves the problem of tunneling support. Compared with other rigid supports, the steel arch has the flexible, stable and reliable bearing capacity, ADAPTS to the load and deformation of soft surrounding rock, has high utilization rate of section, easy support and back, small maintenance, high reuse rate of support recovery, and reduces the use of pit wood, which has obvious environmental benefits.
The steel arch support is safe and reliable, which can effectively reduce the occurrence of roof caving and sheet-side accidents, and improve the stability of mine ventilation system. The promotion and application of the project has improved the safety production conditions of the mine and reduced the production cost, which is in line with the national policy of replacing wood with steel, and has better environmental protection and social and economic benefits.
Steel arch support mainly used for secondary support of mine roadway, mine roadway, and support of tunnel through the mountain.
