ISO 22932-5:2023

Overview

ISO 22932-5:2023 is an international standard developed by ISO Technical Committee ISO/TC 82, focused on the mining sector, specifically addressing terminology related to drilling and blasting. This part of the ISO 22932 series standardizes the vocabulary used within mining operations to ensure clarity and uniform understanding of drilling and blasting terms. The standard includes only those terms with specific and relevant meanings for mining applications, helping industry professionals, engineers, and operators maintain consistency in communication and documentation.

Key Topics

ISO 22932-5:2023 covers a comprehensive set of terms categorized into crucial technical areas related to mining drilling and blasting activities, including:

• Rock Drilling Concepts: Defines essential processes such as back-reaming, bench drilling, blast hole drilling, consolidation drilling, and exploratory drilling. It clarifies procedures and purposes such as drainage drilling for methane or water and different drilling techniques like drifting and dimensional stone drilling.

• Drilling Technologies: Explores advanced methods including rotary drilling, percussive drilling, down-the-hole drilling, raise boring, rotary-percussive drilling, and tube drilling, explaining how each technology contributes to efficient borehole excavation and blasting preparation.

• Boreholes and Bench Elements: Defines terms like blast holes, collaring (the start of a borehole), cuttings created during drilling, and special shothole types such as flanking holes, lifters, and top holes, which are critical for blast design and rock fragmentation.

• Hole Properties: Standardizes descriptions for hole alignment, deviation, depth, length, and drill pattern configurations used in mining operations to ensure precise control and predictability of blast outcomes.

• Rock Support and Reinforcement: Includes vocabulary on rock reinforcement methods, essential for safety and structural support post-blasting, such as bolt holes for rock bolts.

• Explosives and Blast Operations: Covers terms related to explosives, primers, fuses, shotfiring, and firing techniques to clearly describe the blasting process from loading to detonation.

Applications

The practical value of ISO 22932-5:2023 lies in its role as a foundational vocabulary tool for mining engineers, safety inspectors, drill rig operators, explosive technicians, and technical writers. Specific applications include:

• Improved Communication: Facilitates clear communication among multinational teams in open-pit and underground mining operations by harmonizing technical terms.

• Training and Education: Serves as a reference for training materials and curricula for professionals engaged in drilling and blasting, enhancing understanding of core processes and safety procedures.

• Operational Efficiency: Provides uniform terminology for drilling equipment, hole measurements, and blasting parameters, which helps in planning, execution, and evaluation of mining blasts.

• Safety and Compliance: Supports adherence to safety protocols, as precise terminology around blast hole preparation and explosive materials is essential for preventing accidents.

• Technical Documentation: Ensures consistent language is used in regulatory, engineering, and operational documents, improving the quality and clarity of reports, manuals, and standards compliance records.

Related Standards

ISO 22932-5:2023 is part of the broader ISO 22932 series addressing mining vocabulary. Related standards relevant for drilling and blasting include:

• ISO 22932-1 to ISO 22932-4: Cover mining terms related to other mining operations such as excavation, loading, material transport, and more.

• ISO 22475-1:2021: Provides definitions on geotechnical site investigations, relevant for exploratory drilling terminology.

• BS 3618-6:1972: British standard referenced for certain blasting and drilling methods, used as a supporting base for definitions.

• ISO/IEC Directives Part 1 & 2: Outline editorial and technical protocol for the preparation and maintenance of international standards.
