Perforated Metal Belts For Mining

Product Advantages

1.M steel belt flexural section modulus increased by 37 times: the flexural performance of the belt has been significantly improved, which is conducive to the product has a better bearing capacity and deformation resistance in the process of use.

2. Steeliness increased by about 70 times: steeliness is a measure of the ability of the material to resist deformation when subjected to force, increased steeliness means that the product is more robust and stable, suitable for occasions that require higher strength and stiffness.

3.The hardening effect in the cold rolling process increases the tensile strength by 12%-15%: Through the hardening effect in the cold rolling process, the tensile strength of the steel strip can be improved, and the product has better tensile resistance, which helps to improve the service life and safety of the product.

Product Description

1. Combine disk bracket with various anchors: M steel belt can be combined with different types of anchors to form disk bracket, which provides stronger support and fixing effect by linking the scattered anchors to form a whole load-bearing structure.

2. Widely used in various engineering fields: M steel belt is widely used in the field of coal mine underground roadway, working face cutting eye, roadway support, etc. It is especially suitable for dealing with unstable perimeter rock, and effectively improves the support effect.

3. High load-bearing capacity: M steel belt has high tensile strength and bending resistance after optimized design and cold rolling processing, and is able to withstand larger loads.

4. Material cost saving: Compared with the commonly used 11# mining I-beam steel frame, M steel belt can save a lot of material cost under the same supporting effect, which is cost-effective and economical.

Detailed information

As a new type of mine support material, M steel belt has the following features and advantages:

1.Material specification: M steel belt is made of strip steel with a thickness of 2-5mm and a width of 140-220mm. After cold bending into M-shape, the design of anchor holes is processed in the center to provide support for fixing anchors.

2. Structural characteristics: Through the M steel strip to link the scattered multiple anchor rods to form a whole bearing structure. This design significantly improves the overall effect of the anchor support and enhances the stability and bearing capacity of the support structure.

3. Widely used: M steel belt is widely used in the tunnel support of underground coal mine, working face cutting eye, mine chamber and other fields. It is especially suitable for dealing with unstable surrounding rocks, providing more effective support effect.

How to use M-type steel band:

1. Installation preparation: install the rod after the perimeter rock drilling is completed. Pre-design the way of combining the steel band and the rod, and install it according to the design requirements. Use the evaluation rig to install the hole, wait until the rod installation is completed, fasten the tray with the open mother back.

2. Installation of M-type steel strip: Install M-type steel strip continuously according to the need, and use it with the rod. When installing, make sure the combination of steel strip and rod meets the design requirements and closely fits the hole.

3. Characteristics and advantages: M-type steel strip is a new type of mountain support material, which is made of rolled steel plate with a thickness of 3-5mm and a width of 180-320mm through cold molding treatment. Compared with ordinary flat steel strip, M-type steel strip has the advantages of bending section modulus increased by 37 times, stiffness increased by about 70 times, tensile strength increased by 12%-15%, etc., which is able to closely adhere to the surrounding rock and provide better support effect.

Overall, M-type steel strip is easy to install, and can provide high quality support effect by cooperating with rods, which is suitable for all kinds of engineering occasions. Please pay attention to the installation details during use to ensure safety and reliability.
