Hydraulic Expansion Rock Bolt - An Efficient Solution for Mine Support
Hydraulic expansion anchor rod is an innovative anchoring system designed specifically for mine support. It is made of seamless steel pipes, with an outer diameter larger than the drilling diameter, and achieves high-strength anchoring through the principle of hydraulic expansion. Its core advantages lie in its immediate bearing capacity, high anchoring force, and ability to adapt to complex geological conditions, especially suitable for fractured strata and prone to collapse areas in mining. It effectively solves the problem of insufficient anchoring force of traditional anchor rods in weak surrounding rocks and is a key support tool for mine safety production.
