What is rock bolt support:

Rock bolt support is a reinforcement and support method used in surface engineering such as slope and rock deep foundation pit, and underground construction such as tunnel and stope by using mechanical actions such as reinforcement, span reduction, suspension, composite arch and composite beam.

The use of anchor support:

Anchor bolt support generally uses anchor drilling machine to drive holes with predetermined depth and diameter, and then drives rods made of specific materials into the holes. By using the special structure of head and rod body and tail supporting plate, the surrounding rock and stable rock mass are combined to produce suspension effect, composite beam effect and reinforcement effect, so as to achieve the supporting effect.

Advantages of using rock bolt support:

1. Bolt support is to change the mechanical state of surrounding rock itself through the bolt inside the surrounding rock, and form an integral and stable rock belt around the roadway. The bolt and surrounding rock work together to maintain the stability of the roadway. It is an active defense support method and a great change in mine support.

2. Anchorage support has the advantages of low cost, good support effect, simple operation, flexible use and less construction clearance.

3. The anchor rod not only has good supporting effect, but also saves materials, is simple in construction, is beneficial to mechanized operation and has fast construction speed.

Shortcomings of bolt support:

Because bolt support can't close the surrounding rock, it is easy to weather the surrounding rock, and it can't prevent the spalling of fractured rock between bolts.
