The steel mine support is mainly used for the secondary support of mine roadway, mine roadway, and the support of the tunnel through the mountain.
The application of steel mine support raising shed to the intersection point of mining roadway has achieved remarkable results. The U section steel can be used to solve the problem of tunneling support. Compared with other rigid supports, u-shaped steel supports have flexible, stable and reliable bearing capacity, adapt to the load and deformation of soft surrounding rock, high utilization rate of section, easy support, small maintenance, high recycling reuse rate of supports, reduce the use of pit wood, and obvious environmental benefits.
The steel mine support project is safe and reliable, effectively reducing the occurrence of roof caving and strip side accidents, and improving the stability of the 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.
