The Problem
In February 2017 a Coal Mine Worker (CMW) was injured when a hydraulic hose fitting failed under pressure during the use of a hydraulic flow meter. The CMW was positioned inside the pump room and was undertaking the task of a hydraulic tune up. The task requires a calibrated flow meter to be installed in line with the main hydraulic pump system to read the hydraulic flow and pressure the machine is producing. The operator of the flow meter is required to manually adjust the flow meter by hand and watch the pressure and flows on the meter, making it impossible to be out of the line of fire. On the day of the incident a hydraulic fitting failed at the flow meter under 50bar of pressure and shot back contacting the maintainer in the knee luckily only causing minor bruising. During testing procedures the maximum pressure ranges up to 300bar.
The Solution
The implementation of a data logging system that reduces the need to have a person inside the pump room during hydraulic testing. There are two pumps to each main pump. Each pump can now be “turned on” remotely via an electronic remote control. The first individual pump can be cycled and loaded through all curves required to satisfy testing and the change to test, then the second pump can be tested via the flick of a switch. Load to the pumps is applied proportionally through a remote control lever on the test box remote and the pump performance can be seen by the operator outside of the pump room. If adjustments need to be made to the pump regulators the pump is destroked to minimum flow and
to standby pressures using the remote control lever. Once the adjustments have been made the operator can once again remove themselves from the high pressure hose area inside the pump room and return outside and complete the tests again.

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
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
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
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
The operation of a diffusion type gas detectors used in fixed, machine mounted and handheld applications is reliant on the natural equalisation of dissimilar gas concentrations driven by partial pressures inside and outside the detector.
Typically, this equalisation is inhibited (to a greater or lesser degree) by protective filters and barriers surrounding the fragile sensing elements from the typically harsh ambient environments. The accumulation of dust and other foreign matter on the protective filters can further inhibit the diffusion of gas into a detector.
The usual calibration process for a gas detector – typically by a ‘bump’ or ‘challenge’ test – will often fail to detect when a detector is blocked, or partially blocked. This can lead to the ‘calibrated’ detector reading high or low, but with no way to determine if that is the case.
Retrospective examination of records and equipment from Pike River Mine lead to the conclusion that critical detectors were affected by filter blockages, resulting in methane detectors reading approximately one-half of the true concentration.
This presentation explores how a blocked detector can give an erroneous reading, and what steps can be taken to avoid replicating previous mistakes.
