The steel mine supports is beneficial to improve the stress state of the support, improve its bearing capacity and maintain the stability of surrounding rock. In order to ensure the safety of mine production and improve the economic benefit, the mining support must be calculated reasonably in the design and used rationally.
The application of steel mine supports in the intersection point of mining roadway has achieved remarkable results. Compared with other rigid supports, mine 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. High pressure, long support time, easy installation and deformation.
The section utilization rate of the support is high, the steel mine supports is easy to support and return, and the maintenance quantity is small. High reuse rate of support recycling, reduce the use of pit wood, environmental benefits are very obvious.
