Supporting strip mine strip mining W W W - beam steel strip mine roof support steel strip for use W W W steel strip manufacturer price quotes W W steel strip steel picture support strip mining W W W steel plate is a new mine with supporting materials, the product can be used with various combinations of anchor bolt together to form the stent, w strip scattered through it can join together to form a plurality of anchor A whole load-bearing structure, significantly improved the overall effect of the bolt, the incomplete roof strata, w is the strip of surrounding rock instability best deal. W steel band recently, Liupanshui City, Guizhou Province, W-beam with the second session of the Beijing Chinese and foreign well-known enterprises to invest in Guizhou special promotion will be held in Guiyang, focusing on deep processing of coal chemical and coal chemical project information W - beam data related to large-scale industrial project investment attract investment. Liupanshui City seeks to develop coal chemical recycling economy, W steel band to promote industrial restructuring and upgrading. 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 quality kg / m 6.48 Mine W / M steel use:? Anchor beam system not only solve the problem of roadway can also be applied in other sections of roadway large, supporting chambers can also be used in the 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.
