Overview
ISO 19225:2017/Amd 1:2019 is an important amendment to the international standard focusing on safety requirements for underground mining machines, specifically mobile extracting machines at the mining face. This amendment addresses shearer loaders and plough systems used in underground mining operations, aiming to enhance operational safety and minimize risks associated with these heavy, mobile machines. Published by ISO, the International Organization for Standardization, this document updates and refines safety provisions for shearer loaders and plough systems, contributing to safer underground mining environments.
Key Topics
-
Safety Requirements: The amendment refines and adds critical safety requirements tailored for shearer loaders and plough systems utilized in underground mining. These requirements help in mitigating operational hazards and ensuring machine operators' safety.
-
Noise Emission Measurements: A significant section focuses on the assessment and measurement of noise emissions from underground mining machines. It integrates acoustical standards such as ISO 4871 and ISO 11201/11202/11204 to standardize noise measurement procedures and reporting.
-
Testing Conditions for Noise Levels: The amendment specifies precise testing and measurement conditions, including:
- Positions and sequences for acoustic pressure level measurements.
- Detailed instructions for measuring sound emissions for shearer loaders and plough devices.
- Methodology for conducting multiple measurements to ensure accuracy and reproducibility.
-
Installation and Operation Parameters: Amendments modify conditions related to the installation and operational mounting of machines during tests to reflect realistic operational scenarios while ensuring test consistency.
-
Documentation and Reporting: The amendment requires clear documentation and reporting protocols for acoustic emission data, enhancing transparency and compliance.
Applications
ISO 19225:2017/Amd 1:2019 applies widely in underground mining operations where shearer loaders and plough systems are in use. Practical applications include:
-
Mining Equipment Manufacturers: To design and produce machines conforming to internationally recognized safety standards, reducing liability and enhancing machine marketability.
-
Mining Operators and Safety Engineers: For implementing standardized procedures to measure noise emissions ensuring equipment meets safety regulations, protecting worker hearing and promoting safer operational environments.
-
Test Laboratories: Providing clear methodologies for testing acoustic emissions and verifying compliance for mining machinery in controlled environments.
-
Regulatory Authorities: Using the amendment as a reference to enforce mining machinery safety regulations and ensure noise emissions remain within allowed limits.
Related Standards
This amendment references several acoustics-related ISO standards to support its noise measurement and verification requirements, including:
- ISO 4871: Acoustics - Declaration and verification of noise emission values of machinery and equipment.
- ISO 11201:2010: Acoustics - Determination of sound pressure levels in working positions using free-field conditions with negligible environmental corrections.
- ISO 11202:2010: Acoustics - Sound pressure level determination incorporating approximate environmental corrections.
- ISO 11204:2010: Acoustics - Measurement techniques with exact environmental corrections.
Together, these standards ensure harmonized procedures for noise emission measurement, providing reliable, consistent, and reproducible results across global mining operations.
