Steel strip mining M M M strip steel price support strip mining strip mining M steel price lowest price manufacturers want to solve the problem on the election roadway Shandong coal, Shandong coal mine W / M steel can be used in a large section of roadway, supporting chambers can also be used in a landslide, embankment, dam reinforcement. Anchor beam systems are generally less suitable for medium rock steady. In the coal mine roadway applications, saving a lot of steel, wood. Using W / M steel bolt combined with technology and compared with the commonly used mine with 11 # I-beam frame, each shelf bracket can save 856.6kg, so far, w strip with W / M steel with 82,430, compared with 11 # mine roof support beam savings per aircraft steel 73.4kg, compared with 11 # I-beam girder mine U25 mixed type can flinching support bracket, save steel 157.4t, 6049 t were calculated save steel and 12942t . It also greatly reduces the labor intensity and improve the labor environment for efficient mine production safety has brought significant economic and social benefits. W steel band is a new mine supporting materials, perform Q / XWK034-2004 standards. The product can be used with various combinations together constitute the anchor bolt holder, w strip which can be scattered by a plurality of anchor coupling together form a unitary bearing structure, the overall effect is significantly improved anchor, in incomplete roof rock, w surrounding rock instability strip for the best deal. w steel Technical parameters: Model WD280-2.8 Width Thickness mm 280 mm 23.3 mm 2.8 aperture height mm 40 breaking force kn> 284 w steel theoretical mass kg / m 6.48 I plant support equipment as well as steel U-shaped steel bracket W Hollow grouting anchor self-feeding type anchor bolt b19 metal mesh belt anchor bolt tray hydraulic prop pneumatic tensioning cable tensioning equipment manual cable tensioning equipment anchor back anchor back anchor anchor device anchor bolt installation machine cutter machine 10T bolt tension meter anchor bolt dynamometer hydraulic dynamometer WQ-A valve test bench with three U-shaped card cable cable anchor FRP hydraulic prop manually push the slide Move slide control hydraulic prop demolition column machine DJB metal roof beam DFB long metal roof beams cross beams and other steel bolt.
