ANTO Mining W Steel Strip/Band
The W-shaped steel belt is a relatively new type of mine support material. The mine-used W-shaped steel belt is the main component of the anchor mesh support system. The mine-used W-shaped steel belt is the cornerstone of the overall structure of the roof. The commonly used steel belts for important means include mining W-shaped steel belts, flat steel belts with swallow-shaped wing-shaped steel belts, and reinforced trapezoidal π
The difference between anchor rod(rock bolt) and anchor cable
The anchor rod(rock bolt) and the anchor cable are only the difference in quantity, not the difference in quality, but the tensioning medium is different. The tension member of the anchor cable is made of steel strands, and the anchor rod(rock bolt) is made of high-strength precision-rolled rebar as the main steel. Usually, the anchor cable is used in large-tonnage anchoring projects.

Rebar Anchor Bolt - Easy and Fast Bolted Connections
ANTO Rebar Anchor Bolts are used to anchor concrete or steel structures and machinery into concrete base structures. The product range is suitable for moderate loading conditions. This multipurpose anchor bolt is widely approved and adopted. ANTO Rebar Anchor Bolts transfer tension, compression and shear forces to the reinforced concrete base structure (e.g. foundations). ANTO Rebar Anchor Bolts are used with ANTO Column Shoes, SUMO Wall Shoes or even with steel co

Modified Rock Bolt Support for Mining Method with Controlled Roof Bending(2)
Currently, more and more new concepts of the rock bolt support are being developed, the common feature of which is the ability to maintain high load capacity of the support while accepting much greater displacements and deformations of the support. Among the special designs of rock bolt supports we can distinguish those which are characterized by variable geometry along their length.Ortlepp et al. examined the Duracable cable bolt, which had the shape of a sine wave. St-Pierreet al. proposed a sliding effect for the Modified Cone Bolt, w
Modified Rock Bolt Support for Mining Method with Controlled Roof Bending(1)
Abstract: The article presents methods of making the rock bolt support more yieldable, especially for a stratified roof. Alongside the increasing depth of exploitation of raw material deposits,rock bolt support units are more often designed taking into account more intensive deformations and displacements of underground excavations. In the article, a room and pillar method with mined roof bending and roof reinforcement with bolt patterns of 1 m × 1 m, 1.5 m × 1.5 m and 2 m × 2 m is presented. Moreover, the la
How much do you know about mine rock bolt/anchor rod?
A rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be used in tunnels or rock cuts. It transfers load from the unstable exterior to the confined (and much stronger) interior of the rock mass.
Rock bolt, in tunneling and underground mining, steel rod inserted in a hole drilled into the roof or walls of a rock formation to provide support to the roof or sides of the cavity. Rock bolt reinforcement can be used in any excavation geometry, is simple and quick to apply, and is relatively inexpensive. The installation can be fully mechanized. The length of the bolts and their spacing can be varied, depending on the reinforcement requirements.
Coal Mine Roadway Rock Bolt Support
Coal road bolt support is an advanced support technology. Compared with traditional I-steel frame support, it has very significant advantages in technology and economy. Bolt support improves the quality of the roadway, the roof sink is small, and the roadway mai
Application of Anchor Cable Support in Coal Mining(2)
3 Anchor cable support design 3.1 The structure of the anchor cable As shown in the figure 2, the anchor cable is mainly composed of hairy teeth, retaining bands, steel strands, backing plates and anchors.
Application of Anchor Cable Support in Coal Mining(1)
Introduction Coal mine roadway support has experienced the development process from wood support, brickwork support, section steel support, anchor rod support to anchor cable support.Anchor cable has the characteristics of large anchorage depth, high bearing capacity and large prestress, which can obtain ideal supporting effect.Anchor cable support technology is widely used in civil reinforcement engineering, and it is more and more widely used in coal mine tunnel.The prac
Application of split set rock bolt
1.The structure and working principle of split set anchor bolt The mining split set bolt is a kind of mine bolts(mining rock bolts),which is composed of a rod body and a tray, and has a simple structure. Its specifications: the rod body length is 1.7m, 44mm, the pipe wall thickness is 3mm, the pipe seam width is 10-15mm, the outer diameter tray is square, and the size is 130×130× 4.5mm. The pipe-slotted anchor is a full-length anchoring type. Its basic working principle is to use external force to drive the
Rebar rock bolts for coal mines
Rebar bolts for coal mines In China, mine-used rebar bolts are also called non-longitudinal rebar rebars, which are divided into two types: left-handed and right-handed. The nut is special and does not need to be threaded at the end. The specifications are 16mm, 18mm, 20mm, 22mm, 25mm. The length can be processed from 1600mm to 2500mm. The advantage is that no wire is used.
The Split Set stabilizer is a slotted steel tube, with one end tapered for easy insertion into a drill hole. The other end has a welded ring flange to hold the bearing plate. The stabilizer is inserted into a hole slightly smaller in diameter than the tube, using a simple driver tool fitted to the drill. As the tube enters, its diameter is compressed and the slot partially closes. This exerts radial forces along the length of contact with the rock, providing the friction which holds the rock together. The driving force of the drill actively loads the bearing plate
