2019 Conference Presentations

Introduction by Master of Ceremonies Russell White, Master of Ceremonies, Managing Director, Driver Safety Australia CONFERENCE WELCOME Greg Dalliston, Chair, Queensland Mining Industry Health and Safety Conference 2019 CONFERENCE OPENING The Honourable Dr Anthony Lynham, Minister for Natural Resources, Mines and Energy

Paul Spinks is the Game Changer: The Wake Up Call: Paramedic + Trauma Counsellor + Speaker Paramedic Paul Spinks intention was never to be just another stereotype wellbeing speaker, but to throw a hand grenade into the audience to make life changes. A third party wrote: “My husband attended your seminar through Glencore. You struck a chord with him leaving nothing but praise and wanting our two sons to hear your message. He felt so strongly the relevance it had to him and his co-workers. This is to thank you for being able to get through to an average man and to prioritise himself”.

Natascha Viljoen Group Head of Processing, Anglo American Natascha is responsible for Group Processing, a specialist technical services and support function that ensures safe, responsible and optimized processing performance, through step-change technologies and operational excellence. With a Metallurgical Engineering degree from North-West University and an Executive MBA from the University of Cape Town (Cum Laude), Natascha also serves on advisory boards at the Universities of Cape Town, Stellenbosch, Pretoria and Queensland University’s Julius Kruttschnitt Mineral Research Centre, having previously held a non-executive position on Anglo American’s Kumba Iron Ore Board. Natascha has previously worked with ISCOR, Anglo Gold, Anglo Platinum, Samancor Chrome, BHP Billiton and Lonmin.

In continuing with the desire from industry to share in key learnings from site-related incidents and following on from the themes of previous conferences, this session will be an open forum from people (within the industry) who will be talking about key issues and challenges faced at times on their site. This session will be a grass roots session without “spin”. A simple presentation outlining what occurred and what changes have been implemented to ensure that things are being done differently. It is for you to consider the relevance to your site and determine if you have a similar exposure, and the controls in place to reasonably preclude a similar event.

Professor Jianming Wu Visiting Professor of University of Wollongong and Director of AST Australia A/Professor Ting Ren</br/>Director of Centre of Infrastructure Protection and Mining Safety, University of Wollongong Spontaneous combustion (sponcom) of coal remains a major safety issue for underground coal mining operations. Recent heating incidents in Australia further highlight the need of improving current knowledge and practices of sponcom management to ensure safety and productivity of coal mines extracting coal seams that are prone to spontaneous heating. This presentation will provide some the fundamental theory and practices in the early detection, prevention and control of spontaneous combustion of coal. Case studies based on Chinese and Australian coal mines will be presented to demonstrate a range of techniques, including radon detection, jel and fly ash injection materials, that can be practically used for coal heating and fire management. The presentation will also include studies of goaf gas flow dynamics based on computational fluid dynamics (CFD) modelling. Based upon fundamental fluid flow governing equations, computational models are developed to investigate the impact of different ventilation layout and ventilation parameters on goaf gas flow characteristics and in particularly, oxygen leakage and ingress patterns, and hence identification of high sponcom risk zones. Inertisation strategies, using both nitrogen and carbon dioxide, are modelled to optimise operational parameters (e.g, injection flow rate and location etc) for active longwalls and seal-off operations.

Dr Snezana Bajic Technical Services Manager, Department of Natural Resources, Mines and Energy (Simtars) Reliable gas monitoring is a key element to ensure that the mine based controls are effective. Coal mines in Queensland and New South Wales have been facing issues in controlling tailgate methane levels and recently there have been two serious spontaneous combustion events. Legislation and Australian standards make specific requirements for the installation and maintenance of gas monitoring systems. This paper discusses the issues related to gas monitoring, tailgate methane control, alarm set points and proposals for feedback loops on alarm notifications and acknowledgements. The paper will not discuss individual mine events but will focus on reliable gas monitoring to enable early detection and proactive actions to be taken.

Adrian Clarke SHE Manager, Anglo American A proactive safety culture is the desired end state for Anglo American’s Dawson Mine. The journey relies upon the initiation of a strong system to promote embedding the desired safety behaviours within the organisation. At Dawson Mine, this system is “Recognition and Reward Scheme”. The scheme relies on hazard reporting and innovation drives, aligning with the core values of Safety and Innovation. Hazard reporting and associated rectification is critical to improve safety ownership. Prior to implementation, 60% of hazards were reported by the general workforce. This has now increased to 90%, with a total increase in hazard reporting of 20%. The success of the scheme can be attributed to two main factors; firstly, an easy to use system, responsive to feedback, and secondly an immediate reward implication, with those crews achieving high rates of genuine hazard notification receiving recognition. The second success of the scheme is the increase in innovation from the workforce. Innovations are submitted to the site’s Safety, Health and Environment Committee with nominees and award recipients celebrated quarterly across the site. The “Recognition and Reward Scheme” develops a culture of intervention and ‘speaking up’, encouraging employees not to be a bystander but be fully involved in behavioural safety.

Graham Houldsworth Principal Advisor – Strategy and Compliance, Glencore Copper Assets Andrew Russell Managing Director, Actrua Performance Cultures Over the course of the past two and a half years Glencore’s North Queensland Copper Operations have developed and implemented a new generation of integrated safety programs that combine behavioural and system based approaches. Initially a project designed to align best practices in the group and to re-invigorate a focus on behavioural based safety programs, a series of iterations has achieved a suite of integrated and aligned pre-start meetings, leadership development programs and common language for the entire workforce. Partnering with Performance Culture partner, Actrua, a model of co-creation and joint facilitation has allowed passionate employees to develop and own programs that are consistently applied and tailored to the cultural nuances of a large and complex operation spanning multiple geographies. This presentation aims to showcase the program that has been developed, to share the processes undertaken during development and provide insight into the changes in strategic direction and thinking that were required to make the program a success.

Mark Desira Inspector of Mines – Occupational Hygiene The underground mine environment may contain a number of airborne contaminants that affect worker health. This includes diesel plant exhaust (gases and particulate matter) that is emitted into the underground work environment. The classification of diesel exhaust as a Class 1 ‘confirmed human carcinogen’ by the International Agency for Research on Cancer (IARC) necessitates the management of the workers’ exposure to diesel exhaust. The Mines Inspectorate has undertaken a study of underground mines to evaluate the level of risk to mine workers and the effectiveness of differing management strategies for diesel exhaust. In the initial phase of this study, the monitoring results for mine worker exposure to diesel exhaust were collated for underground Similar Exposure Groups (SEGs). The characterisation of the exposure monitoring found that some SEGs (service crews and drilling operations) have higher exposure risk. In the second part of the study, the effectiveness of the control measures applicable to different SEGs were analysed to identify the optimal control strategies. This paper presents the finding that no single control measure is sufficient, and that a multifactorial approach incorporating complementary control measures is required to ensure the effective management of diesel exhaust in underground mines.
