W steel strip steel strip W steel strip mine w strip W shaped steel belt is a new type of mine support materials, perform Q/XWK034-2004 standards. The product can be composed with various bolt combination bolts stent w strip through which the dispersed plurality of bolt coupled together to form a unitary bearing structure, significantly improve the overall effect of the bolt, in the incomplete roof rock formations, w strip handling of unstable surrounding rock is best. w steel strip technical parameters: Model WD280-2.8 width mm 280 thickness mm 2.8 Height mm 23.3 aperture mm 40 Breaking force kn> 284 w steel strip theory quality kg / m 6.48 Mine Description W / M steel strip anchor beam system not only solved roadway support problems, and can also be used in other large cross-section of the roadway, the chamber's support, can also be used in landslides, embankment, dam reinforcement. The anchor beam system generally applicable to the rock formations below the moderate stability. In the coal mine roadway support applications, and save a lot of steel and wood. With W / M steel bolt combined technology and used 11 # mine compared with I-beam frame, each frame bracket can save 856.6kg, so far, w steel strip with W / M steel with 82,430, compared with # 11 mine-beam shed support per aircraft steel 73.4kg savings than flinching # 11 mine-beam beam U25-type mixed support bracket, save steel 157.4t saving steel 6049 t were calculated and 12942t . Also a significant reduction in the labor intensity, improve the labor environment, efficient for coal mine production safety has brought significant economic and social benefits.
