In a significant milestone for global mining safety, Henan ZongXiang Heavy Industry Import & Export Co., Ltd., a leading Chinese manufacturer of mine support solutions, has announced the export of a substantial batch of 42mm split set stabilizers. This shipment, comprising thousands of high-quality friction rock bolts, is en route to international partners in Southeast Asia and Australia, underscoring ZongXiang's commitment to delivering reliable, innovative ground control products. As underground mining operations face increasing demands for efficiency and safety, these stabilizers represent a critical advancement in rock reinforcement technology, poised to enhance stability in tunnels, shafts, and excavations across diverse geological conditions.

Split set stabilizers, often referred to as friction bolts, are engineered for rapid installation and immediate load-bearing capacity. The 42mm variant, one of ZongXiang's flagship sizes, features a slotted steel tube crafted from premium Q235B or Q355B carbon steel, folded to form a robust, expandable structure. With an outer diameter of 42mm and a wall thickness of 3mm, these bolts are designed for boreholes slightly smaller in diameter—typically 41.5mm—to ensure a friction-fit that exerts radial pressure along the entire length. Upon insertion using a simple driver tool attached to a standard drill, the tube compresses, partially closing the longitudinal slot and generating three key forces: radial compression against the rock wall, frictional resistance to prevent slippage, and bearing support from the integrated pallet plate. This tri-force mechanism actively stabilizes the surrounding rock mass, transforming potentially unstable formations into secure, three-dimensional stress fields.

What sets ZongXiang's 42mm split sets apart is their versatility and proven performance in demanding environments. Ideal for underground coal, metal, and non-metallic mines, they excel in applications ranging from railway and hydropower tunnels to powerhouse caverns and sewage systems. Unlike traditional expansion shell bolts that require complex assembly, split sets install in seconds with minimal equipment—just a jackleg drill or stoper—reducing downtime and labor costs by up to 50%. Pull tests conducted post-installation confirm capacities exceeding 20 tons, with long-term monitoring ensuring sustained integrity over months. Environmentally, their non-galvanized finish minimizes corrosion risks in humid conditions, while the recyclable steel aligns with sustainable mining practices.

This export batch, produced at ZongXiang's state-of-the-art facility in Zhengzhou, Henan Province, adheres to stringent GB standards and undergoes rigorous quality controls, including ultrasonic testing for weld integrity and dimensional precision. Each bolt measures up to 3 meters in length, customizable per client specifications, and comes bundled with bearing plates for optimal load distribution. "Our 42mm split sets are not just products; they're lifelines for miners," states a ZongXiang spokesperson. "This shipment to key markets reflects our dedication to innovation, backed by over a decade of R&D in friction stabilization." The order, valued at competitive factory-direct pricing, highlights ZongXiang's growing footprint, following recent successes in Indonesia and Europe.

As the mining industry grapples with deeper excavations and seismic challenges, ZongXiang's export initiative arrives at a pivotal moment. These stabilizers mitigate risks like roof falls and sidewall collapses, fostering safer workplaces and boosting operational productivity. With global demand surging—driven by infrastructure booms in Asia-Pacific—ZongXiang invites inquiries for tailored solutions, including 33mm, 39mm, and 47mm variants.
