Prestressed Material
Mining Steel Strand 28.6mm, with a no less than 990 kN breaking force ,could be well used in deep underground roadway roof stabilization ,
the application of the product in deep coal mines has advantages such as strong anchoring,
which will have a positive effect on improving the safety coefficient of coal mine tunnel support structures,
promoting safety production and technological progress in the coal mining industry.
ADVANTAGES
-Primary advantages
Mining Steel Strand 28.6mm has high load-bearing capacity and deformation resistance, which can be better applied to deep coal mine roadway support engineering below 500 meters and corrosive working environments containing salt and alkali, and can effectively avoid sudden collapse and other malignant accidents caused by the possible instantaneous fracture of surrounding rock
