Yenakievo Iron & Steel Works’ Makeevka Branch mastered the production of thread bar, the use of which simplifies and accelerates the process of rock bolting, an advanced method for affixing mine tunnel roofs.
Rock bolt works immediately after installation, improving mine tunnel stability as rock stratification is prevented and the size of inelastic deformation areas is reduced.
Sales have already started of thread bar with a strength class of 500 MPa and diameters of 20 mm and 22 mm.
Yenakievo Iron & Steel Works’ Makeevka Branch also rolled a test batch of thread bar with a strength class of 600 MPa and a diameter of 20 mm. This product will allow to reduce the metal used in mine rock bolts by another 17%. Development of the regulatory documents and industrial trials for this product are planned in the nearest future.
