Mine Rock Bolts use advanced research and development technology. As a good support equipment, they are mainly used for coal mine roadway support. There are three main layout methods for existing mine rock bolts: concentrated point layout, concentrated line layout, uniform surface layout.

Specific operating principles of the three layout methods of mine rock bolts:

1. The concentrated point layout are arranged in a concentrated manner, usually under the columns. It can make full use of the vertical force transmitted from the superstructure to balance out some of the water buoyancy; due to the concentrated arrangement of the anchor rods, it is also more convenient for external waterproofing under the basement floor; for the case of insufficient bearing capacity of individual rock bolts, there are more mine rock bolts to share it, which have strong resistance.

2. The concentrated line layout is usually under the basement floor beam. Due to the relatively concentrated arrangement of the mine rock bolt, it is also more convenient for external waterproofing under the basement floor; for the case of insufficient bearing capacity of individual rock bolts, there are more mine rock bolts to share it, which have strong resistance.

3. The uniform surface layout is uniformly arranged, evenly arranged under the basement floor. Suitable for all soil and rock masses; the basement floor beams and slabs have a small reinforcement, and the centralized point arrangement is recommended for hard rocks. The concentrated line layouts are recommended for hard and hard rocks; the uniform surface layouts are recommended for all situations.
