Mining Anchor Rods Can Be Used In Mining Projects

Mining anchor rods can be used in mining projects

Mining anchor refers to a tool applied to mine roadway and underground engineering perimeter rock support, can ensure the stability of mine roadway and underground engineering perimeter rock, the use of mining anchor, can realize the end of the anchor, lengthening anchor and the whole anchor; easy to operate, low price, etc., widely used in coal mines, railroads, hydropower and other engineering all kinds of roadway

Support. Anchor is the basic component of tunnel support in contemporary coal mines, which reinforces the surrounding rock of the tunnel together and makes the surrounding rock support itself. Nowadays, anchors are not only used in mines, but also used in engineering technology to reinforce the main body of slopes, tunnels and dams. Anchor as a deep stratum tensile member, it is connected with engineering structures at one end, and the other end is deep in the stratum, the whole anchor is divided into free section and anchoring section, the free section refers to the tension at the head of the anchor to the region of the anchor solid, and its function is to apply prestressing force to the anchor.

Anchor classification and characteristics.

1.Fixed anchor:Mainly used to support mine roadway, can be divided into single symmetric and double symmetric two kinds, fixed anchor installation is simple, good support effect, but can not adjust the length.

2、Active anchors: mainly used to support the surface and underground construction, can be divided into two kinds of tension anchors and pressure anchors. The movable anchor has the function of adjusting the length and is made of high-strength steel with high tensile and compressive strength, which is suitable for deep anchor control in difficult situations.

3、Hydraulic anchor: mainly used to support large cross-section horizontal roadway and different position section of the roadway, set the hydraulic cylinder on the fixed section of the anchor, can be fixed-length anchor construction, hydraulic anchor has a simple structure, easy to operate, and reliable support role and so on.

4、Composite anchor: It is a new type of anchor combining fixed anchor and movable anchor with innovative design structure. The boom and the anchor body form a whole, so that the fixed end and the movable end can be relatively displaced, effectively solving the problem of supporting limitations of a single anchor.
