W strip application principle
W is a new strip mine supporting materials, also known as roof strip, perform Q/XWK034-2004 standards. Is made of high strength alloy plate cold. The product portfolio can be composed together with a variety of anchor bolt integrity, scattered through the multi-W Root steel bolt banded together to form a monocoque structure, significantly improve the overall effect of bolting, the incomplete the better application of the top slate is weak roof rock and coal is the best choice, widely used in the mine tunnel face cut eye, Cave Room and other areas of the roadway, is more effective in dealing with unstable rock good.
W strip technical characteristics
1, the raw materials used in high-strength alloy steel strip;
2, has a higher rigidity and strength;
3, W-section steel bending modulus increased 54-fold;
4, WD strip in the cold hardening process can improve the tensile strength of 28-46%.
Anchor beam system the following are generally applicable to moderately stable rock. Roadway not only solve the problem, can also be applied to other large sections of roadway, the supporting chamber can also be used in the landslide, embankment, dam reinforcement. In the coal mine roadway applications, significant savings of steel, wood. Significantly reduced labor intensity, improve the working environment of workers, as mine efficient and safe production to bring significant economic and social benefits.
