The mining anchor rod tension meter is a new type of mining pressure monitoring instrument, mainly used to measure the stress situation of anchor rods in the surrounding rock of tunnels at different stages.
The purpose is to monitor the stress situation of anchor rods installed in rocks through anchor rod force gauges. This product has small size, light weight, simple structure, convenient use, intuitive observation, accurate reading, and reliable performance.
Compared with traditional metal anchor rods, mining anchor rods have irreplaceable advantages. In terms of performance, the rod body is easy to cut and provides protection for the cutting head of the coal mining machine; Explosion proof and anti-static, no sparks generated during cutting, extremely beneficial for standardized construction of tunnels, especially suitable for high gas concentration areas; High strength and corrosion resistance, lightweight and easy to operate, with a weight only 1/4 of the same specification steel anchor rod. It can be conveniently used in narrow spaces such as tunnels and coal mines, making construction easier and reducing labor intensity for workers. The price is lower than that of metal anchor rods, which can reduce the cost of anchor rod support by 10%.
