Self Drilling Hollow Anchor Rock Bolt System

Self Drilling Rock Bolt is a type of fastener used in civil engineering projects to provide reinforcement and support for rock formations or unstable surfaces. Unlike traditional bolts that require pre-drilling, self-drilling rock bolts combine drilling and anchoring in one process. They are commonly used in underground mining operations, slope stabilization, tunneling, shoring, and foundation repair.
Materials – Self Drilling Rock Bolts are typically made from high-strength steel, such as Grade 40Cr or 45CrMo steel, which is both strong and durable. Steel with a galvanized or epoxy coating is also commonly used to protect against corrosion.

Uses – Self Drilling Rock Bolts are used to provide additional stability and support in a wide range of applications, including:

Tunneling: used to support the surrounding rock and maintain the stability of surrounding structures during excavation.

Slope stabilization: used to prevent rockslides and the collapse of unstable cliffs or slopes.

Foundation repair: used to provide additional support to build foundations that have weak soil or bedrock.

Mining: used to reinforce the walls and ceilings of underground mines.
Features – Self Drilling Rock Bolts are designed to be easy to install and offer several benefits over traditional bolts, including:

Reduced installation time and labor costs.

Improved safety, as the risk of accidents during drilling is reduced.

Ability to install in areas with restricted access.

High load capacity and superior anchoring performance.
