china coal 0001 Arc Plate Net Shell Support Keywords: Net Shell Support, Stainless Steel Support, Steel Supports Price Introduction of Arc Plate Net Shell Support Supporting of soft rock tunnel excavation has been one of the key technical problems which affects the further development of coal industry production and construction of our country . Deep mine ground pressure intensity is high, under the condition of mining influence and impact ground pressure and strata control is especially difficult, thus support system is more and more strengthened, such as the need to reduce the frame from u-shape set, strengthen the link rod, and even to use U36 steel;spray the anchor net supporting to reinforced by steel arch, or and anchor rope combined support, surrounding rock grouting, etc; Although this can achieve certain supporting effect, but support cost is very high. Therefore, China coal group design to create a new type of flat net shell components, the main supporting characteristics of arc plate net shell components summed up as: "while digging, while supported edge, "before soft to hard", enough stiffness, process simple,low price." Characteristics of Arc Plate Net Shell Support 1,"While digging, while supported edge",timely support Arc Plate Net Shell Support can use waste rock filling, grey package after wall, concrete precast slab, such as filling, network frame and the tunnel contour quickly close to stick, while digging, timely support, so that on the one hand can make the support resistance of support was able to play in time, to timely reinforce the surrounding rock and to work under the stress state in three; On the other hand, have the effect of slow pressure, pressure, lead to the uniform support along the perimeter stress, is in good working condition. 2,Arc Plate Net Shell Support has enough "rigidity" 3,"Just moderately soft, before soft to hard". Arc Plate Net Shell Support force has a complex ingredients: expansion and creep of rock mass, reduce the strength of long, crushing of rock mass adhesion coefficient reduced values, etc., all show the macroscopic displacement of rock mass and any rigid support to prevent displacement will be entirely itself in disadvantage. Therefore, the stability of the laneway to end support, work together to complete of the surrounding rock. Reticulated shell scaffold, while under high in-situ stress reaction in surrounding rock, making convergence of surrounding rock in supporting under the control of convergence, by stent supported edge, the edge of broken rock mass convergence pressure unceasingly, forming a stable bearing ring, together with stents to assume the role of in-situ stress. The scalability of Arc Plate Net Shell Support comes from two aspects: (1) the contact of the spatial grid steel supports and surrounding rock itself has certain yielding; (2) the junctions between the reticulated shell scaffold piece and piece of wood plate.

china coal 0001 U-channel Tunnel Steel Support Keywords: U-channel Steel Support, Tunnel Steel Support, Steel Support For Sale Introduction of U-channel Steel Support For Coal Mine U channel steel support cross section is shaped like the letter "U" in English. National production of u-shape cross-section shape, geometric parameters and material is different, at present China''''s production of u-shape model mainly include stepping, U25, U29, U36 these four. The stepping and U25 waist position; U29, U36 belongs to the ear. Stepping up the carrying capacity is very low, now rarely production. U channel steel support with high initial supporting force, supporting intensity big, easy to install and is not easy to deformation, so often used in the manufacture of roadway yielding metal stents, mine, mine roadway secondary supporting of roadway, and mountain tunnel support support purposes Use, effectively reduce the roof caving u-shape set, help such as accidents, safe and reliable, and enhances the stability of the mine ventilation system. Choose u-shape flexible support, better solved the difficult problem of the excavation support Structure of U-channel Steel Support For Coal Mine 1.Top Beam Top beam is circular arch, its amount depending on the cross section of roadway with different sizes, support force, transportation conditions, section 1 and section number. 2.Column leg There are three kinds of back leg , one kind is upside for circular arc form, for straight line at the bottom; The second is all for the curved shape, and only one radius of curvature; The third is all for the curved shape, but there are two curvature radius. Back leg in welding under the base, the base of large plate on the hard and soft; 3.Connection parts Fitting is a support section and internode card device, can the internode connection effect, can also be connected the two compression steel joint parts, provide pre-tightening force, make the u-shape between friction, thereby ensuring that the arch has a certain resistance and certain drop-off. 4.Rod between support Rod between support is to enhance the relative stability, the support bracket from longitudinal connection, form a whole. 5.Back-up material Back-up material is u-shaped steel support between supports and surrounding rock filling material, improve the stress of the support, to improve the bearing capacity and maintain the stability of surrounding rock. Characteristic of U-channel Steel Support For Coal Mine 1,Stand high pressure , support long time, easy to installation and not easy to be out of shape 2,compared with other rigid support , U-shaped steel support has a scalable and reliable carrying capacity to adapt to load and deformation of soft rock. 3,U-shaped steel support bracket support cross back high utilization convenient small amount of maintenance. 4,U3 steel support recycling reuse rate, reduce prop use, very obvious envir
