Product Description

What is a left hand rock bolt?


Left-handed full-thread bolts are mainly used in mines where rock formations such as coal mines are not hard enough. bolts are generally used together with anchoring agents to achieve end anchoring or full anchoring in mines. Left-handed full-thread bolt is made of high-strength HRB500 or HRB600, which can provide high load-bearing capacity to protect mine safety.


The one-way left-handed rebar bolt without longitudinal reinforcement can be used in all kinds of mines and underground projects,and is especially suitable for the support of coal tunnels with wire mesh. It has achieved good technical and economic effects.


The structural features of the anchor rod: the full length of the body has a rolled continuous thread, and the full length is of equal strength; the fastening end is provided with a prestressed gasket and a ball nut. It is superior to the bolt processed by round steel, and is a new type of bolt with material saving, labor saving and equal strength.

Q: 9.How do resin capsules work?

A: Resin capsules market are a tried and tested solution across a range of diverse applications for supporting high loads in concrete expansion. These are extensively used to fix rock bolts, wooden dowels or anchor bolts with complete column grout for strata control at mining and tunneling sites to eliminate the risk of roof falls. Resin capsules offer several advantages such as permanent anchorage, rapid high-strength development, controlled setting time, and superior resistance to vibrations as well as corrosion, which makes them preferable for use in mines, tunnels, and dam construction.

Q:10. resin capsule market

A: Polyester resin capsules are used extensively in underground coal mining industries worldwide, where rock bolts are used as a primary support. As a result, polyester resin capsule anchored rock bolts are rapidly gaining acceptance in the underground metalliferous mining industry.

Q: 11.What role does resin capsule play in mining?

A: Resin capsules play a vital role in supporting mining excavations. It is primarily used as an anchoring medium for rock bolts and cable bolts, and provides necessary roof and sidewall support to the underground excavations. It enhances the inherent strength of the rock mass stabilization and can be used with hydraulic and pneumatic type bolters. Owing to the operational ergonomics of the resin/bolt system, the installation time of rock bolting reduced significantly. Additionally, with the increasing use of resin capsules, accidents caused by the movement of strata in underground mines have significantly reduced.
