The Impact of Non-Technical Issues on Decision-Making by Coal Mining Incident Management Teams The impact of non-technical issues on decision-making by coal mining incident management teams. Ruth Grace Fuller BEng Hons Civil Engineering Grad Dip Psychology BSc Hons Psychology Grad Dip Secondary Education A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2014 Sustainable Minerals Institute Abstract A serious incident in an underground coal mine can claim many lives in an instant. The lives of those who survive the initial moments can be dependent on the decisions made by the incident management team (IMT). The IMT is a team of mine employees assembled immediately upon the discovery of an incident to manage the response. Evaluations of annual emergency exercises conducted at underground coal-mines in Queensland have indicated that IMT decision-making is generally sub-optimal. This finding was echoed by the Royal Commission into the New Zealand Pike River Coal Mine Tragedy that occurred in 2010. In many other high-reliability roles technical and non-technical issues have been found to impact decision-making. The goal of this research is to explore the role of non-technical issues in emergency decision-making following an underground coal mining incident. A review of the Queensland emergency exercise reports, direct observation of emergency simulations, and interviews with twenty-five mining personnel with real-life incident management experience at underground coal mine emergencies has led to the development of a non-technical skills taxonomy for decision-making in mining IMTs. The decision-making process in a mining IMT has been shown to be a broad socio-psycho-technical process within which technical and non-technical issues cannot be separated. Technical, social and cognitive skills are imperative to maintain adequate communication, situation awareness and optimal decision-making throughout the emergency management process.

The effects of this tragic event have also been felt by the mining industry in Australia. As an industry we are constantly aware of terms such as “Emergency Preparedness” and “Emergency Response Management Plans” and in fact, numerous seminars and forums are facilitated to study these topics in detail. This begs the question, “how well is your organisation really prepared if it was faced with a major disaster such as that which occurred at Pike River”? The incident management team, mine manager, mines rescue and other emergency organisations responding to the Pike River mine explosion faced significant challenges on planning a re-entry into the mine by rescue teams.

  • The Impact of Disasters on Independent Contractors: Victims of Circumstances
    The Impact of Disasters on Independent Contractors: Victims of Circumstances Felicity Lamm Nadine McDonnell Ryan Lamare Auckland University of Technology Introduction The year 2010-2011 will be known in New Zealand as annus horribilis. Within a period of five months New Zealand had not only experienced a major mining disaster but also two major earthquakes. All three disasters were located in the South Island of New Zealand. While remarkably in the first earthquake no one was killed, the second 6.3 magnitude earthquake centred in Canterbury s largest city Christchurch killed 185 people in February 2011. Three months earlier on the 19th November 2010 a series of methane explosions at the Pike River Coal Mine (PRCM), situated outside the small regional West Coast town of Greymouth, killed 29 workers. Thirteen of the dead were contracted workers. At the time of the Pike River Coal Mine explosion, out of a workforce of 200, over 80 independent contractors were employed at the mine. Most of the independent contractors operated local, small businesses, employing on average 10 people. Pike River Coal Mine Ltd not only subcontracted manual labour (skilled and unskilled) but the company also outsourced aspects of the mine design, financial and environmental risk assessments, and a great deal of the management of occupational health and safety (OHS), such as mine ventilation. Shortly after the explosions at PRCM, the mine was closed and the company went into receivership. As most of the independent contractors were unsecured small creditors, neither they nor their workers nor their families received any money owed to them by Pike River Coal Mine Ltd (in receivership).
