What is BS EN ISO 22721:2012?

BS EN ISO 22721:2012 is a technical standard that pertains to conveyor belts for use in underground mining. It provides guidelines and requirements for the design, construction, installation, maintenance, and inspection of conveyor belts used in these applications. This standard aims to ensure that conveyor belts in underground mining environments are safe, reliable, and efficient.

Design and Construction of Conveyor Belts

The design and construction of conveyor belts for underground mining operations are critical aspects covered by BS EN ISO 22721:2012. This standard specifies the materials to be used for different components of the conveyor belt, including the carcass, cover, and reinforcement. It also outlines the requirements for belt width, thickness, elongation, and strength. By adhering to these specifications, conveyor belts can be designed and constructed to withstand the demanding conditions present in underground mines.

Installation and Maintenance Guidelines

Proper installation and maintenance of conveyor belts are crucial for their safe and efficient operation. BS EN ISO 22721:2012 provides guidelines for the installation process, including considerations for belt alignment, tensioning, and tracking. It also outlines the maintenance procedures required to keep the conveyor belts in optimal condition, such as regular inspections, cleaning, and lubrication. These guidelines help minimize downtime and maximize the lifespan of the conveyor belts in underground mining applications.

Inspection and Testing Requirements

Regular inspection and testing of conveyor belts are essential to ensure their ongoing performance and safety in underground mining environments. BS EN ISO 22721:2012 sets out the requirements for both visual and physical inspections, including criteria for assessing belt wear, tear, and damage. It also specifies the methods and equipment to be used for testing the conveyor belts' physical properties, such as tensile strength, elongation, and adhesion. Adhering to these inspection and testing requirements helps identify potential issues before they lead to operational disruptions or accidents.
