Mining row steel beams The row steel beams can be matched with various single hydraulic props to form metal brackets, which can be used in coal mines to step back on horizontal and gently inclined working surfaces or with larger machine heads. The empty roof area can be used. He can also choose the roof to support the empty roof area over a long span, which can better realize a larger working space without pillar support on the working surface, thus improving labor and working conditions. .
