M-Shaped Steel Strip

Product Details

M-shaped steel strip is a new type of mining support material, also called top plate steel belt, M-shaped steel strip using thickness 2-5MM width 140-220MM strip steel, cold bending into M-type, in the middle of the processing of the anchor hole in the steel strip. Through the M-shaped steel strip to the dispersed anchor rods linked together to form a whole load-bearing structure, significantly improve the overall effect of anchor support, M-shaped steel strip is widely used in coal mine tunnel, face cut eye, mine chamber and other areas of tunnel support, to deal with the unstable perimeter rock effect is better.

M-shaped steel strip use method：

M-shaped steel strip installation and use is extremely simple, after the perimeter rock drilling and then install the rod, in advance the steel belt according to the design requirements and the rod combination, the use of evaluation drilling rig on the tracing of open for installation to be installed after the rod installation is completed, the tray and open the mother of the back of the tight, and so on, you can finish or installation.

M-shaped steel strip is a new type of mountain support materials, M-shaped steel strip using a thickness of 3-5mm width of 180-320mm rolled steel plate After the cold / type, in the M-shaped steel strip processed with the rod armchair distance equal to the tracing of the rod holes in the steel belt M-shaped steel strip compared to the same flat steel belt bending section modulus increased by 37 times, the stiffness increased by 70 times or so, to improve the tensile strength of 12% -15% in the surrounding rock tightly tightly attached to the Company with high quality products. Products.

Specifications and Parameters

Product Description

M-shaped steel strip can be combined with a variety of anchor common disk bracket, M-shaped steel strip that is, through the W / M steel belt to dispersed more than one rod link up to form a whole load-bearing structure, M-shaped steel strip is widely used in coal mines under the roadway, the face of the cut eye, mine and other areas of the roadway support, to deal with the effect of unstable surrounding rock is better, at present, the domestic production of various groups of companies in the mines and the depth of the M steel belt with the mined 500-1000 meters, the ground stress, surrounding rock, and the depth of the M-shaped steel strip has been 500-1,000 meters, the ground stress, and the surrounding rock. At present, in the mines produced by the domestic group companies, the depth of M-shaped steel strip has reached 500-1000 meters, the ground stress, surrounding rock force and deformation are complicated and diversified, a single rod support can no longer meet the broken roof, composite roof roof plate, roof pressure of the roadway support requirements, and with the anchor rods and the W/M steel belt composed of anchor beam system, can effectively control the roof, but also should be used in the breakout of the roadway bunker room support. M-shaped steel strip with the commonly used 11# mining I-beam frame compared to, can save a lot of material cost.
