Overview

prEN 14591-3 - "Explosion prevention and protection in underground mines - Protective systems - Part 3: Water troughs for explosion barriers" (CEN) specifies the requirements and test methods for water troughs used in water trough barriers in underground coal mines. As a part of the prEN 14591 series, this CEN prestandard focuses on ensuring water trough components reliably contribute to explosion mitigation strategies in mining environments.

Key Topics

This standard addresses technical and conformity aspects relevant to water trough systems without prescribing site-specific designs. Key topics typically covered include:

• Scope and definitions related to water troughs and barrier systems
• Design and material requirements to ensure durability, corrosion resistance and suitability for underground coal-mine conditions
• Performance criteria that water troughs must meet when integrated into explosion barrier systems
• Test methods to verify mechanical integrity, leak tightness and functional behavior under operational and explosion-related conditions
• Inspection, installation and maintenance guidance to support long-term effectiveness and safe operation
• Documentation and marking requirements for traceability and conformity assessment

(Note: The standard defines requirements and test procedures rather than prescribing specific dimensions or proprietary solutions.)

Applications

prEN 14591-3 is intended for practical use where water trough barriers are part of an explosion prevention and protection strategy:

• Mine operators and safety managers use the standard to select and specify compliant water trough components during mine design, commissioning and upgrades.
• Equipment manufacturers and suppliers refer to the standard to design, test and certify water trough products for sale into the underground coal-mining market.
• Testing and certification bodies apply the test methods in the standard when assessing product conformity and performance.
• Design engineers and contractors integrate the standard’s requirements into barrier layout, installation procedures and maintenance plans to meet regulatory and best-practice expectations.

Related Standards

• Other parts of the prEN 14591 series (protective systems for explosion prevention/protection) - refer to adjacent parts for complementary requirements and system-level guidance.
• Applicable CEN standards and national mine-safety regulations should be consulted for installation, operational compliance and certification processes.

prEN 14591-3 is an essential reference for stakeholders involved in explosion barrier design, manufacture and verification, helping ensure water trough systems perform reliably within underground coal-mine explosion protection schemes.
