Patrick Tyrrell – Australian Coal Industry Research Program
ABSTRACT
ACARP assists the Australian coal industry to develop and adopt technology and mining practice that leads the world. The program is entirely funded, owned and managed by the Australian black coal producers.
ACARP was established in January 1992 and has had many great achievements that improves the safety and health of our people throughout its many years. What sets ACARP apart from other areas of research is the industry monitors that have direct input to the research that is been undertaken through a collaborative approach that utilises the experience and technical strength of both the coal mining industry and research institutions in solving technical problems and addressing issues of significance to the industry’s long-term future. Any proposed research project that is strongly supported by a mine site and is of interest to a number of coal operations is encouraged. Safety and environment remain key drivers in the program and will continue to be the focus of much of the underground work and a significant component of the open cut and coal preparation programs.
Priorities have been developed by the five technical committees responsible for proposal development and selection and are separated into the areas of:
• Underground
• Open Cut
• Coal Preparation
• Technical Market Support
• Mine Site Greenhouse Mitigation
While the current priorities are not prescriptive they should act as a guide.
The Current Priorities are: Underground:
• Prevent Harm from Spontaneous Combustion, Ignitions, Mine Fires, Extreme Heat, Explosions, Outbursts, Coal Bursts, Ventilation and Strata Failures – Improved understanding, detection, prediction, protection, selection and design of major hazard management systems.
• Management of Health – including mental health and fatigue.
• Communication to Employees and Contractors of Safety Measures – Improvement such that the information, training and instruction is understood and retained.
• Operator Interfaces and Vehicle Interaction – Improving equipment, automation and remote monitoring and control, also addressing musculoskeletal disorders, improved ergonomics and
• Improved roadway conditions.
• Airborne and Noise Contaminants – Reduce exposure to airborne dust, diesel emissions, and noise.
• Emergency Response Measures – Adequacy and effectiveness.
• Investigation of key practices, including legislative, leading practice alternatives and culture.
Open Cut: The industry is looking for direct or indirect improvements in health and safety across all mining and exploration operations. Areas of interest for open cut mining are:
• Investigation of key health and safety issues and management systems, practices and culture, including legislative leading practice alternatives.
• Management of health including mental health, alcohol and other drugs, return to work and fatigue, e.g. by reduced exposure to noise, vibration, dust and heat, by determining mental health of employees, etc.
• Protection and removal of personnel from hazardous situations such as those around unstable ground, in the vicinity of voids, and around excavations particularly during truck loading.
• General improvement to the health and safety of mining and maintenance operations through novel manual
• Handling aids, including automated technologies or equipment changes.
• Improving equipment operator interfaces, vehicle interaction management, automation and remote control.
• Development of safety in the design of systems and equipment that leads to the reduction of occupational exposure at the source, e.g. noise, dust, blast fumes etc.
• Improve the communication to employees and contractors of safety measures such that the information,
• Training and instruction are provided in a method that allows cognitive retention.
• Development of a cognitive recognition method which addresses the normalising effects that are created due to the human brain predominantly operating in a subconscious mode and failing to recognise changes in their environment that could lead to adverse outcomes.
ACARP facilitates industry and researchers to work together for a common goal that is the improvement of the health and safety of our industry and our people, this is a journey that we all share together.

ABSTRACT
Use of compressed air to blow out or “clean” electrical cabinets is a routine maintenance task across the Queensland Coal Industry. Elevated levels of harmful dust can engulf the blow out operator for extended periods and increase the risk of developing lung diseases including Coal Workers Pneumoconiosis and silicosis.
In 2017 the Queensland Mines Inspectorate reported that approximately 50% of all respirable dust and Respirable Crystalline Silica (RCS) exceedances in surface coal mines was directly related to the use of compressed air for cleaning down enclosures and equipment during maintenance activities.
Respiratory protection has historically been viewed as the primary control to protect the health of blow out operators as dust controls at the engineering level or above have not been considered to be feasible.
Blow out of electrical cabinets on Komatsu 960E haul trucks have been targeted for an engineering dust control project at Hail Creek Mine. The project has focussed on the following areas:
• Sealing of cabinets
• Application of positive pressure
• Local exhaust ventilation / vacuuming
• Identification of alternative cleaning methods
• Measurement of control performance
This paper describes the dust control project along future direction for application of common principles to other equipment such as draglines and excavators.

ABSTRACT
In May 2015 the first confirmed case of mine dust lung disease (MDLD) in the Queensland Coal industry in over 30 years was reported to the mines inspectorate. A number of cases followed that typically related to underground coal mine workers with extensive exposure history in Queensland, interstate and abroad. In October 2016 the first surface coal mine worker was confirmed with MDLD proving this hazard was not isolated to underground mines. The reidentification of MDLD in Queensland prompted several extensive reviews of the health surveillance system and the respirable dust regulations. This resulted in significant regulatory reforms around exposure monitoring, reporting requirements and the establishment of a central exposure data base.
In January 2018 the Chief Inspector of Coal Mines requested all surface coal operations to provide personal exposure monitoring data collected since the introduction of the risk based legislation. This paper reviews exposure data collected from Queensland surface coal mines and wash plants during the period 2001 – 2017.
Specifically the paper discusses:
• Mean exposure trends across various similar exposure groups for respirable coal dust and respirable
crystalline silica (RCS)
• Personal monitoring programmes and sampling rates
• High dust exposure tasks and single exceedance data
In addition, the study draws comparison with exposure data collected from Queensland coal mines during the eighties (80’s).

ABSTRACT
Since the first case of CWP in over twenty years was reported in Queensland in 2015 there have been 66 confirmed cases of mine dust lung disease among current and former QLD mine workers. As a result ACARP commissioned research into a number of questions relating to monitoring and controlling coal dust exposure.
The project had a number of aims which include the following areas: 1) establishing the state of the art with respect to current dust suppression and prevention controls and their effectiveness. 2) Reviewing the basis used for setting an exposure standard for respirable coal dust 3) The current trends in exposure data and any underlying points of concern or interest 4) current research into reducing exposure to respirable coal dust. 5) The capacity to monitor respirable coal dust in real time – what techniques are available and what are their limitations and 6) Future directions for research into better control of respirable coal dust exposure.
The research seeks to answer these questions and better define the next questions for future research. This paper will present the progress results of the Improving Respirable Coal Dust Exposure monitoring and Control research project.

ABSTRACT
In early 2016, with Millennium Mine nearing the end of its planned mine life, the site took on a new challenge – to use auger mining to maximise resource recovery by endeavouring to win coal from two final highwall positions. The team set about engaging a specialist auger mining contractor who had worked in Queensland for a number of years. The contractor had a system of work in place based on experience gained in both the United States (US) and Australia.
However, the previous research relating to the effectiveness of the controls was conducted in the US in the early 1990’s. The absence of a real time gas monitoring system on the auger led the Queensland Coal Mines Inspectorate to issue a (S169) directive to suspend augur operations at Millennium pending resolution of a range of concerns relating to the risk assessment, standard operating procedure (SOP) and work instructions.
The directive was extremely broad and difficult to achieve.
Over the next six weeks the Mine set about developing a detailed revision of the risk assessment and SOP. However, with no baseline data, the project lacked the defined processes to verify and confirm the existing controls. The Operation was therefore unable to restart.
In May 2016 the Mine sought a review of the directive by the Chief Inspector. Ultimately this led to a revised directive (S166).
The use of this revised regulatory approach allowed for:
• Verification of the risk assessment controls;
• Development of a series of new systems of work to be tested;
• New controls to be proven through a framework of research and development of the mining system.
A series of test and verification programmes was developed using risk assessment techniques that involved technical experts from various specialist fields.
This then allowed the project to develop in stages and to progressively deliver an ‘acceptable’ level of risk based on proven methods of control.
At each stage a plan was developed, submitted and reviewed with the regulator with a subsequent update of the section 166 directive. The results were then further reviewed with the regulator as part of defining the next steps. Success was achieved by the regulator, Mine operator and the contractor working closely to develop a series of best practice controls using the latest available technology, underpinned by fundamental risk management practises.
In March 2018 the final directive was closed.

ABSTRACT
The mining industry provides a lot of information to the Mines Inspectorate associated with safety and health matters at mines and quarries. While the inspectorate may be the holder of this information, it is available to industry to assist in analysis if matters that may be plaguing their mine.
By using industry data that has been provided a deep dive into electrical fires on mobile equipment will be examined to highlight where there are common issues that contribute to the development of a fire and then contribute to the sustainability of a fire. Recommendations from the data will be extracted to allow mines and more importantly, Original Equipment Manufacturers and third part equipment modifiers, to allow design consideration to reduce the number of mobile equipment fires and financial loss to a mine.

ABSTRACT
In 2015 Coal Workers Pneumoconiosis was re-identified in Queensland Coal mine workers.
Since then, the department, coal mine companies and worker representative groups have been working together to reform the Coal Mine Worker’s Health Scheme and protect worker health.
There have been a number of important learnings along the way and this paper will present a summary of the journey over the past two years to create a better health scheme for coal mine workers, and areas where these learnings can be leveraged in the future.

ABSTRACT
Evidence-based reviews have concluded that ‘debriefing’, also known as The Mitchell Model has little effect, or that it actually worsens the trauma symptoms. Yet, many sites, often unknowingly, are still using this model.
This presentation will discuss what Psychological First Aid is (and isn’t), and how Leaders can effectively apply it to ensure that their people are supported in the immediate aftermath of a Critical Incident.

ABSTRACT
Statistics show that almost half of Australians will experience a diganosable mental health condition at some time in their lives. While these conditions can potentially impact a workers safety, productivity, health, and return to work duration; there is also a well-documented link with suicide. Alarmingly, suicide is the leading cause of death for Australians aged 25-44; and research indicates that men in semi-skilled occupations like mining are indeed at an even greater risk.
Ernest Henry Mine acknowledges the prevalence of mental health issues, with management support numerous site-based initiatives were implemented to assist workers with this emerging and complex trend. The program has been successful in raising awareness about Mental Health and Wellbeing; enhancing accessibility to appropriate help/support; improving the village/camp lifestyle; promoting engagement; and facilitating a more positive work environment.
While these mental health initiatives are a step in the right direction, ongoing effort is required to reduce stigma and to provide an environment that is both protective to the development of mental health conditions and conducive to recovery. It is hoped that other mining operations can draw learnings from Ernest Henry Mine’s initiatives.

ABSTRACT
Obesity is a major problem in Australia, with over 70% of Australian’s being overweight or obese. Rates of obesity in NSW coal miners are significantly worse (83.4%). Workers who are obese have higher rates of absenteeism, reduced productivity, increased injury and illness, slower recovery rates and increased workers’ compensation costs.
Building on from the Blueprint for the Management of Overweight and Obesity in the NSW Mining Industry, the healthy weight initiative – RESHAPE – was developed. . RESHAPE is an intervention framework based upon the World Health Organization’s Healthy Workplace Model and provides a worksite framework, with coordinated actions, that aim to contribute to a site and industry-wide change in the prevention and management of overweight and obesity.
Findings from a current study that is investigating what obesity management programs have been trialled within the coal industry, the outcomes of these at a site level and information on the challenges and benefits of these programs, will be presented. These findings will provide industry with insight into the next steps which can be considered for the prevention and management of overweight and obesity as a critical part of the industry’s overall focus on the general health of its employees.

ABSTRACT
Risk can often be seen as a disparate set of problems that seem to be unrelated and can result in Boards, Executives and Senior Managers being overwhelmed and exposed as the business struggles to address its issues across many competing priorities.
So how do we manage this? We must first identify and understand the critical risks the business is exposed to. The concept of risk lends itself to the Pareto principle, that is; 80% of a business’ risk profile is related to 20% of its risks (i.e. the critical few). Given this, it is appropriate for a business to focus on the ‘critical few’ rather than the ‘trivial many’ and to drill down deep into the causal pathway of the ‘critical few’. The aim of this is to ensure that effective controls are available to be implemented when required.
We must then understand the organisation’s (including the Boards, Executives and Senior Managers) appetite for managing these ‘critical few’ risks. The appetite for managing these ‘critical few’ risks is a function of the organisation’s culture and we must understand what motivates (or demotivates) the Board, Executive, Senior Managers and employees to implement (or not) the relevant management system requirements including activation of the critical controls when required.
When we truly understand what motivates people to manage the ‘critical few’ risks and we hold people accountable for the availability and effectiveness of the controls, then and only then will we have a culture that will enable a business to mitigate/manage its risk profile and optimise its business performance.
In this session, we will reflect on several case studies to support these contentions and provide evidence of this approach.
