1. Product Introduction

The Anchor Bolt / Anchor Cable Protection Device is a safety protection product developed by Shandong Ronghui specifically for underground mining environments. It focuses on the safety protection and durability enhancement of the exposed ends of anchor bolts and anchor cables in complex underground conditions. Made from high‑strength, anti‑aging materials, the device is installed over the exposed ends to effectively protect workers from scratches and cuts caused by sharp protrusions, prevent the anchor cables from rubbing against or colliding with ventilation ducts, cables, and other underground equipment, and resist corrosion from moisture and aggressive substances in the mine environment.

2. Key Advantages

1. Extended service life, significantly reduced maintenance costs

Compared with traditional unprotected solutions, this device can extend the service life of anchor bolts and anchor cables by more than 2 times, substantially prolonging the service cycle of the anchoring system and greatly reducing material and labour costs associated with later replacement and repair.

2. Easy installation and reusability

The device is quick and easy to install and remove, requiring no special tools and without interfering with normal construction progress. A single unit can be reused, with a reuse rate of over 80%, reducing long‑term protection costs by more than 60% compared with disposable solutions.

3. Flexible adaptation and strong versatility

The product can be flexibly adapted to various underground environments and different specifications of anchor bolts and anchor cables, without the need for additional customisation. This further reduces procurement costs and shortens delivery lead times.

4. Multi‑faceted protection, safe and reliable

• Personnel protection – Covers sharp exposed ends to effectively prevent workers from being scratched or cut.

• Equipment protection – Prevents anchor cables from rubbing against or colliding with underground equipment such as ventilation ducts and cables.

• Corrosion protection – Effectively resists moisture and corrosive substances in the mine environment, prolonging the service life of the anchoring system.

• Anti‑ejection protection – Effectively prevents the ejection of anchor components, ensuring a safer working environment for underground personnel.
