High-strength anchor rods for mining are a kind of support equipment specially used in mining engineering. They can effectively enhance the supporting capacity of soil and rock mass, and ensure the stability and safety of surrounding rock of mine tunnels and underground engineering. The following is a detailed introduction to high-strength anchor rods for mining:
Definition and Use
Definition: High-strength anchor rods for mining are a kind of reinforced concrete prestressed anchor rods, usually composed of anchor rod pipes, anchors and grouting materials, which can be adjusted in length and connected as needed.
Use:
1. Mining engineering: used for shaft wall support, tunnel slope stability, cave wall reinforcement, etc., and can also be used for support and reinforcement of ground buildings.
2. Geological disaster prevention and control: prevent rock landslides, collapses, earthquakes and other disasters, and improve the safety and stability of underground engineering.
3. Geotechnical engineering: rock wall reinforcement, tunnel support, subway, tunnel and other underground engineering support and reinforcement.
Features and advantages
High strength: High-strength anchor rods for mining are generally made of high-strength alloy steel as materials, with good tensile strength and corrosion resistance.
Easy to install: The installation of anchor rods is relatively simple and can quickly adapt to various complex construction environments.
Strong flexibility: The length and diameter of the anchor rod can be adjusted according to the specific project requirements to meet different support requirements.
Good durability: Made of high-strength materials, the anchor rod has a long service life and good durability.
Technical parameters
Anchor rod material: high-strength alloy steel, such as Q235, 335, 400, 500 and other materials.
Anchor rod diameter: generally between 20mm and 32mm, the specific diameter is determined according to the tunnel conditions and support requirements.
Anchor rod length: designed according to the height of the tunnel, generally between 2m and 5m.
Anchoring length: generally between 1.5m and 2m, to ensure that it can effectively resist the deformation and pressure of the tunnel surrounding rock.
Prestress: adjusted according to the deformation and pressure of the tunnel surrounding rock, generally between 6kN and 10kN.
Support force: It needs to be determined through relevant calculations during the construction process, generally between 10kN and 20kN.
Market situation
Brand and manufacturer: There are multiple brands of high-strength anchor rods for mining on the market, such as Yizi Mining, Haoyang Engineering, Zhongxiang Support, etc. These brands are usually provided by professional manufacturers, such as Handan Yizi Mining Accessories Manufacturing Co., Ltd., Liaocheng Haoyang Engineering Materials Co., Ltd., etc.
Price range: The price of high-strength anchor rods for mining varies depending on factors such as brand, material, and specifications. Generally speaking, its price range ranges from a few yuan to tens of yuan, and the specific price needs to be determined according to the actual procurement situation.
Purchase suggestions
Clear demand: When purchasing high-strength anchor rods for mining, you must first clarify your support needs and engineering conditions, including the height, width, and surrounding rock stability of the tunnel.
Choose a brand: Give priority to well-known brands and reputable manufacturers to ensure the quality and after-sales service of the anchor rods.
Pay attention to technical parameters: Carefully understand the material, diameter, length, anchoring length and other technical parameters of the anchor rod to ensure that it meets the engineering requirements.
Consider the cost: Under the premise of meeting the engineering requirements, reasonably control the procurement cost and choose products with higher cost performance.
