Anglo American and Glencore have reported the progress they have made towards meeting the global industry standard on tailings management (GISTM).

Last week, Rio Tinto released details on its tailings facility.

Anglo American has set out its progress towards bringing its 12 tailings storage facilities (TSFs) that are currently within the two highest potential consequence categories into conformance with GISTM.

“We have made very significant progress towards conformance with the GISTM over the last three years, building upon our already high technical standards,” Anglo American chief executive Duncan Wanblad said.

“We continue our prudent approach to align with a number of specific GISTM requirements, as well as the social and community aspects that are already encompassed in our comprehensive social way management system. We are addressing the few outstanding areas and have set out the work needed to get us there.

“As an industry, we have a clear ethical imperative to do everything possible to ensure that TSFs are managed to the highest standards as we work together to build greater levels of trust with all our stakeholders. GISTM’s role in driving continuous improvement across the industry with full transparency is beyond doubt.”

Glencore also reported its conformance to GISTM for its TSFs with ‘very high’ or ‘extreme’ consequence classifications.

“We have taken a rigorous and technically robust approach to applying the GISTM, which goes beyond self-assessments and includes independent third-party assurance,” Glencore said.

“We welcome the greater transparency it has brought around the management of these important facilities. We are pleased with the progress we have made over the last three years… Based on our ongoing TSF management systems and independent third-party assessments we have in place for our TSFs with ‘very high’ and ‘extreme” consequence classifications we believe that any gaps in conformance are identified and managed appropriately.”

Both miners have committed to working towards conformance in respect of its TSFs that are within the other three lower consequence categories, ‘low’, ‘significant’ and ‘high’, by August 2025. This in line with the commitment made by all ICMM member companies.

UNIVERSAL STANDARD PROPOSED TO MINIMISE MINING IMPACT

QN-15-Sibelco2An organisation that develops international industry standards has set its sights on reducing the long-term impact of mining, which could have implications for the quarrying industry.

ISO, the world’s largest developer of voluntary international standards, has formed a new subcommittee that will focus on minimising the long-term damage that can potentially be caused by mining activities.

The aim of creating these mining reclamation management standards is to improve the relationship between the mining industry and local communities, as well as the quality of life of residents that live in the surrounding areas.

Subcommittee chair Professor Sun Joon Kim explained that the conflict that could occur between these parties could sometimes grow beyond reasonable mediation.

“International standards for mining reclamation management can be beneficial as these internationally agreed guidelines help avoid excessive claims or profits from one side, leading to a win-win situation,” he said.

Developing a universal guideline
While it was acknowledged that many countries had established effective local standards, Kim said ISO would be developing a “general guideline that can be applied universally” and which can address “more detailed fields and standards that meet each situation … if necessary, special situations must be standardised separately”.

Commenting on the standard development process, ISO mining technical committee chair Reinhard Reinartz said, “The first and most important step is for [the mining technical committee] to identify and understand in detail these different needs. Then we will be able to identify common ground with other topics and fields, making sure we are not isolating issues.”

Reinartz explained that both the mining committee and its mining reclamation management subcommittee would be working with related ISO technical committees – especially in the field of machinery – to exchange findings, discuss next steps and, where possible, create a common interdisciplinary standard.

“This will ensure best practices are being shared for the benefit of the industry and highlight where we need to be industry-specific,” he concluded.

An ISO spokeswoman confirmed to Quarry that the subcommittee would be focusing on all types of mining, including both underground and surface mines or open-cut mines such as quarries.

“After the suggestion of a general guideline applicable to any specific mining activities, the next step for the subcommittee would include developing guidelines of more detailed mining objects. During this stage, the subcommittee would consider whether or not quarrying needs special standards,” she explained.

ISO has published more than 19,500 international standards since it was founded in 1947. The organisation comprises a network of national standards bodies from 163 countries and is headquartered in Geneva, Switzerland.

Overhaul for safety legislation in WA

The WA state government has committed to modernising the safety legislation covering mining, petroleum and major hazard facilities (MHFs) in Western Australia.

With legislation for all three areas undergoing reform, there is an opportunity to review the legislative structure and consider consolidation of the current Acts and regulations.

Department of Mines and Petroleum resources safety executive director Simon Ridge said the department was seeking stakeholder input into the process.

“There are five options regarding how we can structure the safety aspects of mining, petroleum and MHF legislation,” Ridge said.

“These options range from consolidating all resources safety elements into one unified act, partially consolidating the current safety acts or leaving the acts as they are.”

Legislated safety obligations for industries in the resources sector are currently contained within six different parliamentary acts and associated regulations.

Mr Ridge said the initial focus of the consultation was only on the structure of the Acts.

“This is one of the first steps as we look to reform safety legislation in WA’s resources industry,” he said.

“Once this has been finalised, we will then consult separately on proposed changes to the content of the legislation.”

The department has engaged Marsden Jacob Associates to conduct the independent consultation process.

The consultation paper and further information about how you can contribute to the process are available on the Marsden Jacobs website.

Submissions must be directed to Marsden Jacob Associates by 5pm WST on Friday, 19 December 2014.

Changes to Australian Standard AS 4024.1 (By Pilz Australia)

Changes-to-Australian-Standard-AS-4024-1-654841-lThe revision will closely align AS 4024.1 Series with European machinery safety standards

 

Standards Australia announces several revisions to the Australian Standard AS 4024.1 Series – Safety of Machinery to align with global standards and strengthen workplace safety.

The revised parts have been individually issued at this stage with the entire standard due to be released as a 2014 version once the application guide (part 1100) is finalised later this year.

The AS 4024.1 series provides guidelines to designers, manufacturers, suppliers, employers and users of machinery to help reduce the risks of working with, or near machinery.

Pilz Australia Managing Director Scott Moffat explains that the Safety of Machinery Standard has grown in relevance over time, and has recently been adopted as an AS/NZS Standard. The revision will closely align it with the European machinery safety standards.

According to Mr Moffat, the revision is a logical step to continue to update AS 4024.1 Series to European standards as they lead the world in this area of machinery safety.

Standards Australia’s Technical Committee said the principle task of the 2014 revisions for the AS 4024.1 Series was to consider the latest international standards and incorporate these into the original 2006 Standard.

Overall, 19 Parts have been revised (1201, 1302, 1401, 1601&2, 1604, 1701-4, 1801&3, 1901-7); two new Parts have been added (1303, 1503); and four Parts superseded and withdrawn (1101, 1202, 1301, 1802) with the application guide (1100) to follow.

Key changes in the Australian Standard AS 4024.1 include:

The risk assessment approach parts 1201 & 1303 (new) have been updated to reflect the global standards of ISO12100 (Machine Safety, General principles of design, risk assessment and risk reduction) and ISO14121-2 (Practical examples of Risk Assessments);

A new Part 1503 that now gives the practitioner the option to design safety related control systems using ISO13849-1 and the Performance Level (PL) approach. Part 1501 (Category approach) remains in the standard and the option is still open to the designer;

Parts 1602 (Interlocking Devices) and 1604 (Emergency Stop) are now both direct text adoptions of their international standards, ISO14119 and ISO13850 respectively;

Guarding Parts 1801 (Safety Distances) and 1803 (Minimum Gaps) are also now both direct text adoptions of their international standards, ISO13857 and ISO13854.

Mr Moffat adds that Pilz Australia and New Zealand is well placed to assist customers with the revised Standard, given the company’s rich European background aided by a large number of technical experts locally and globally who are very familiar with all the European standards.
