3 advantages of rock bolting support in mining engineering

Rock bolting support is an active support with a simple structure. It can effectively control the deformation and displacement of the surrounding rock, ensuring the integrity and stability to the greatest extent. Rock bolting has been widely used in various fields, mainly used for roadway support in mining engineering. Compared with the traditional frame support, the rock bolting support has its distinctive advantages:

1、 Good supporting effect
Rock bolting belongs to "active" supporting, which conforms to modern rock mechanics and surrounding rock control theory in terms of support principles. After the anchor bolt is installed, the overall bearing structure will quickly be formed to strengthen the surrounding rock. By mobilizing and using the stability of the surrounding rock, its bearing capacity can be fully utilized to effectively control the deformation of the surrounding rock of the roadway. Compared with the traditional frame support, the rock bolting support can better adapt to the large deformation of the rock surrounding roadways and improve the roadway maintenance status by maintaining the integrity and stability of the surrounding rock.

2、 High construction efficiency
Compared with frame support, the support materials used in rock bolting support are less and lighter, which greatly reduces the amount of material transportation and the labor intensity, and improves work efficiency during roadway excavation. The process of anchor construction operation is simple and can closely follow the excavation working face. It is convenient to organize the excavation parallel operation and one-time formation of the roadway, which realizes rapid excavation and support mechanization.

3、 Better economic benefits
Using rock bolting support can reduce the material quantity and support cost. It does not occupy the effective section of the roadway, so it can save a lot of materials. At the same time, rock bolting support can reduce the workload of roadway maintenance and save costs.
