Coal Mining Split Set Friction Rock Bolt Supporting

Apart from mine roadways, these anchors also can be applied in a variety of different programs. they may be effective in presenting high-power and long-lasting support to railroads, highways, hydropower tasks, and similar endeavors. by using the use of longitudinal ribless rebar resin anchors, these systems benefit more desirable energy and sturdiness to withstand the heavy masses and forces they encounter.

Longitudinal ribless threaded rod anchoringcan be prolonged in length through threaded connection to meet unique engineering desires. this anchor rod has excessive tensile, shear and torsional strength, that could offer dependable assist and fixation. it is broadly utilized in tunnels, underground mines, water conservancy tasks, transportation and one-of-a-kind fields to boost rock, soil or concrete structures. the advantages of threaded anchors without longitudinal ribs include clean set up, slight weight, reusability, and quick production duration.longitudinal ribless threaded rod anchoring can improve engineering creation efficiency, reduce engineering price, and has an extended service life. all in all, threaded anchor with out longitudinal rib is an important engineering aid cloth, that may provide sturdy and dependable support.And is widely applied in severa underground engineering and civil engineering.

Anchor Characteristics:

1. superficially it restricts the rock and soil frame from the proper frame.

 2. macroscopically it'll growth the brotherly love of the rock and soil frame.

 3. anchor rods aren't best used in mines, but extensively utilized in engineering generation for lively reinforcement of slopes, tunnels, dams and so on.

 4. anchor is the simple element of tunnel help in modern underground mining, which binds the perimeter rock of the tunnel together, in order that the fringe rock supports itself.

Product Selection and Working Conditions：

1.  product preference: assist designers regular with the roadway segment of the encompassing rock geological conditions to encounter the encircling rock to pressure parameters, after which blended with realistic enjoy, can pick out one-of-a-kind specifications of the anchor.

2.  the use of operating conditions: users should have drilling and set up system, resin anchors and so forth. on the way to increase the impact of guide, after the installation of anchor rods, plus the set up of anchor net anchor cable and slurry.the drilling size and intensity ought to be used in step with the specifications of anchor rods and anchoring agents; thinking about the power conditions of the web page, it's far advocated to prioritize the usage of pneumatic anchor drilling rigs or hydraulic anchor drilling rigs in order that the drilling and set up are accomplished inside the identical gadget: for the use of excessive rock hardness web page selection of the 7655 wind hammer drilling, pneumatic coal drilling and stirring installation. stirring set up of rated output speed ≥ 400 rpm output torque, for the full-period anchoring must be 2 60nm; for give up anchoring need to be 240nm machine.

Advantages

1.  anchor stop and fastening cease do not require machining.

2.  equal energy for the complete length, high material usage.

3.  large anchorage force.

4.  Pre-stressing hot piece is provided, easy to control the installation quality.

5.  Fast installation speed.

6.  It is made according to the rotating direction of the digging tool, so that the anchor will not exit during the operation.
