bolt support

In roadway support, bolt support saves cost of support over profile steel, economic performance is distinctly improved.

This analysis method can be used as a reference for the design, construction and research of bolt support for similar tunnels.

The pre-stress is an important parameter of the bolt support and would have an important influence to the mine roadway support effect.

Finally technological methods were brought out to prevent roof falling on bolt support mining roadway.

The numerical simulation research shows that wall rock looseness range can guide the determination of bolt support parameters.

According to the result, the bolt support can effectively restrict the relaxation of surrounding rock and reinforce the surrounding rock.

Anchor drilling machine also effects rapidity of anchor bolt support.

The high stressed bolt support technology would have a good suitability to the mine roadway in the structural stress zone.

Based on the occurring mechanism of slough rock burst, the mechanism to weaken shock with bolt support in coal roadway is analyzed.
