Overview
ISO 19426-1:2018, titled Structures for Mine Shafts - Part 1: Vocabulary, is an international standard published by the International Organization for Standardization (ISO). This document provides a comprehensive set of terms and definitions relating to the structures used in mine shafts, forming the foundational vocabulary for the entire ISO 19426 series. As mining terminology often varies by region and diverges from conventional engineering language, the standard clarifies preferred terms and alternative expressions to promote clear, global communication within the mining and engineering industries.
The scope of ISO 19426-1 ensures that professionals involved in mine shaft design, construction, operation, and safety have a standardized lexicon for consistent understanding, particularly when dealing with structural components and equipment specific to mine shafts.
Key Topics
-
Standardized Mine Shaft Terminology
ISO 19426-1 addresses unique mining terms, especially those related to mine shaft structures such as shafts, stages, conveyances, guides, and associated equipment. By establishing consistent definitions, the document supports accurate interpretation and application of safety and engineering principles.
-
Structural Components Vocabulary
The standard defines critical structural elements including:
- Bridles, transoms, and hangers: These structural frames and members support conveyances like cages and skips.
- Guides and guide rollers: Essential for controlling conveyance movement within the shaft.
- Emergency arresting structures and dogging systems: Critical safety components designed to prevent accidents during overwind or loss of rope tension.
- Stages and platforms: Access and working areas within the shaft for personnel and equipment.
-
Conveyance Types and Equipment
The document covers terminology related to conveyances such as cages, skips, kibble buckets, inspection baskets, and control conveyances, defining their roles in personnel and material transport within vertical and incline shafts.
-
Safety and Operational Terms
Detailed definitions related to safety mechanisms like overspeed devices, emergency stopping devices, fall back arrestors, and protective platforms are included to support operational reliability and worker protection.
-
Alternative Terms
Recognizing variations in terminology across countries, the standard lists alternate terms with preferred ones highlighted, enabling international collaboration and reducing misunderstandings.
Applications
-
Mine Shaft Design and Engineering
Engineers and designers use ISO 19426-1 vocabulary to ensure clarity in technical specifications, structural design documentation, and communication with stakeholders worldwide.
-
Safety Management
Standardized terminology assists safety professionals in assessing risks, implementing protective measures, and conducting training on mine shaft structural components and conveyance systems.
-
Global Mining Operations
Mining companies operating across borders benefit from harmonized terminology, facilitating procurement, maintenance, and operations with consistent understanding of shaft structures.
-
Standards Development and Compliance
Regulatory bodies and standards committees can reference ISO 19426-1 for precise terminology in drafting legislation, codes, or supplementary standards related to mine shaft safety and construction.
Related Standards
-
ISO 19426 Series
Part 1: Vocabulary is foundational for other parts in the ISO 19426 series covering design loads, structural principles, and safety requirements for mine shafts.
-
ISO/TC 82 Mining Standards
Developed by ISO Technical Committee 82, this vocabulary complements other mining-related standards to ensure comprehensive standardized practices in mining engineering.
-
International Electrotechnical Commission (IEC) Collaboration
In cases where electrotechnical components intersect with mine shaft structures, IEC standards work in tandem with ISO 19426-1 for integrated safety and design requirements.
