The impact of legislation and other factors on the safety performance of Australian coal mines

Parkin, Raymond John, Mining Engineering, Faculty of Engineering, UNSW January 2009 (has links)
The theme of the thesis is to investigate the current safety paradigm in the Australian coal mining industry and establish if the safety performance is improving. The number of fatalities, serious bodily injuries and high potential injuries is unsatisfactory according to community standards. People are still being killed and there is little evidence of a sustained improvement trend over the last decade. Lost time injuries have reduced dramatically, but are now plateauing and over the last few years along with high potential injuries and other safety indicators are trending upwards. This research has found that hundreds of serious injuries are not being reported which would have a significant effect on safety indicators in the Industry. Fatigue and awareness issues as well as travel times to work are having a major impact on safety at work, which is particularly evident when employees are working 12-hour shifts. The rapid expansion of the mining industry has required the growing use of contractors, hence creating a more inexperienced workforce. Another significant finding is that there is a close association between the level of fatalities recorded and the growing use of contract labour in the industry. This research has demonstrated that the current approach to prosecution is counter productive, as it inhibits thorough safety investigation and creates a defensive rather than a proactive safety culture. This approach has resulted in unwillingness by companies to examine the root causes of accidents and incidents for the fear of being prosecuted. This research has shown there is a lack of trust between mining companies, the unions and the inspectorate. It has been stated that miners lives are at risk because of the shortage of Inspectors in Queensland and that the inspectorate was not meeting its compliance obligations. There is a "disconnect" between what mining companies aspire to achieve at the corporate level with their safety management systems and what is achieved at the coal face. The thesis has demonstrated that safety performance is deteriorating and in order to improve this situation recommendations have been made regarding prosecution, contractors, fatigue, safety and health management systems, hours of work, audits and remuneration for inspectors.

A qualitative analysis of post-traumatic stress disorder experiences at the Slater Coal Mining industry

Dumakude, Celani Carol January 2012 (has links)
Thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in the Department of Psychology, Faculty of Arts at the University of Zululand, South Africa, 2012. / This qualitative study investigated the prevalence of post-traumatic stress disorder within the mining industry. It further reviewed systems used to manage the same disorder following a disastrous mining accident in the Slater Coal Mines. There are key challenges that were reviewed as part of improving diagnosis and management of post-traumatic stress disorder. Two focus groups consisting of six African mineworkers, working in the Slater Coal Mines, were conducted. All participants were isiZulu speakers. The data was analysed using grounded theory, which is a qualitative technique. In using this data analysis technique, data labelling, open coding, axial coding and selective coding were the steps that were followed as a guide. Research findings indicated that post-traumatic stress disorder is prevalent within the mining industry and differs from post-traumatic stress. Existence of post-traumatic stress disorder was represented by symptoms such as intrusive thoughts, avoidant behaviours and terror. Further, causes of mining accidents and accident management measures were the findings. Different work conditions were implicated in the study as contributing to trauma in the mines in addition to accidents that happen underground.

The role of legislation and management practices in the coal mining industry on the Olifants River catchment, South Africa

Zermatten, Carrie 20 November 2012 (has links)
The economic development of South Africa has relied heavily on coal mining and water quality is adversely affected by mining - thus coal mining poses a significant risk to South Africa’s water resources. Ensuring judicious use and management of natural capital is always a complex undertaking but the benefits to the mining industry and society as a whole, derived from thoroughly laid-out plans, a supportive but strict regulatory environment and decision-making processes based on sound, scientific information are immense. Value addition to mining products is important to promote conservation of assets and resources. Using the Olifants Water Management Area as a case study, the chemistry of groundwater associated with coal mining was characterised. General concepts regarding the relationship of geology to water chemistry are surmised. Copyright / Dissertation (MSc)--University of Pretoria, 2012. / Geology / unrestricted

Factors contributing to unsuccessful rehabilitation: a case study investigating the rehabilitation practices in Opencast Coal Mines in the Mpumalanga Province, South Africa

Gule, Nontobeko 05 August 2021 (has links)
The coal mining industry has played a significant role in the development of the South African economy. Coal supplies about 70% of South Africa's primary energy and is likely to remain the country's major source of energy despite the increasing trends towards renewable energy. Even though the industry has significantly contributed to the development of the country, it has also caused significant impacts on the environment with concomitant socio-economic impacts. Historically, once a coal measure was exhausted, mining companies would cease production and abandon the mines without proper rehabilitation of the environmental degradation caused by their mining activities. As a result of this, the South African Government introduced mining and rehabilitation legislation to mitigate the environmental and associated socio-economic impacts of mining. Rehabilitation guidelines for opencast coal mines were developed to provide detailed guidance for achieving successful and sustainable rehabilitation, to mitigate pollution post-mining. Despite the more stringent legislative framework and the development of international standard rehabilitation guidelines, successful mine rehabilitation remains a challenge. This research project aims to develop a better qualitative understanding of the status, challenges, gaps and opportunities pertaining to current rehabilitation practices in the case of opencast coal mines in the Mpumalanga Province of South Africa, and in so doing, establish the contributing factors of unsuccessful rehabilitation. The dissertation draws on a comprehensive review of published literature and an analysis of semi-structured interviews with rehabilitation experts. The study found that the current rehabilitation practices in the Mpumalanga opencast mines are not to the standard required by the legislative framework nor prescribed by rehabilitation guidelines. As such, the current rehabilitation practices are not yielding successful and sustainable rehabilitation. According to the findings, the rehabilitation practices are hampered by physical and non-physical systemic challenges that thwart the achievement of successful rehabilitation. The study analysis shows that shortcomings in the application and enforcement of the legislative framework contributes to the legislation not achieving its intended objectives as well as the development of other physical and non-physical systemic challenges that hamper the achievement of successful rehabilitation.

The arbitration review board: an analysis of its development and impact on the arbitration process in the coal industry

Bourne, Glen Steve January 1987 (has links)
The Arbitration Review Board existed in the bituminous coal industry from 1974 to 1981. Established during the 1974 contract negotiations between the Bituminous Coal Operators Association and the United Mine Workers of America, the ARB represented an effort to obtain consistency in arbitration decisions. The ARB operated as an industry appellate board designed to hear appeals of arbitration awards, and the decisions of the ARB were contractually mandated as industry precedents requiring arbitrator compliance. Although the parties terminated the ARB in 1981, they have continued to incorporate the precedent decisions in subsequent contracts. This study utilizes both a qualitative assessment and an empirical analysis of arbitration decisions to determine the impact of the ARB on the arbitration process in the coal industry. Structured interviews were conducted with former ARB members, arbitrators, management representatives, and union representatives to gather information with which to construct a complete historical perspective of the ARB's inception, operation, and termination. A total of 44 individuals were interviewed. The empirical assessment involved a content analysis of 300 arbitration decisions to determine the extent to which arbitrators have adhered to the ARB precedents. Conclusions of the research suggest that the ARB has had a profound impact on coal industry arbitration. Arbitrators increasingly adhered to ARB decisions during its existence, and have continued to exhibit a high degree of adherence following the ARB's termination. The difficulties encountered in implementing the ARB and the factors contributing to its termination are discussed. / Ph. D.

Supply chain constraints in the South African coal mining industry

Mathu, Kenneth M. 11 1900 (has links)
Thesis. (D. Tech. - Business, Faculty of Management Sciences)--Vaal University of Technology, 2010. / The study explored the South African coal mining industry and it’s role players to establish the causes of the bottlenecks/constraints experienced in the coal mining industry supply chain. A qualitative research paradigm methodology was used. Both theoretical and philosophical assumptions were utilised with inferences from and references to works by other researchers to broaden the knowledge horizons for the study. Thirteen supply chain executives and professionals from the key role players in the coal mining industry were interviewed and provided invaluable input for the study. The study determined the presence of communication barriers between the industry role players in the public and private institutions that culminated in main themes and sub-themes being established from which the industry constraints were uncovered. The study identified six main constraints affecting the various role players within the coal mining supply chain and it culminated in the model that would enable the industry to minimise such constraints. To this end, the study proposes the development of an Integrated Strategy for the Development of Coal Mining (ISDCM).The model is based on the public and private partnership arrangement that would alleviate most of the prevailing constraints when implemented. The model would furthermore have the capacity to rectify most of the existing constraints. It would be funded from the commercial sector and would operate on triple bottom lines of economic, social and environmental factors, with equal weight. This is a desirable direction for the future in order to maintain sustainable development. Emanating from the study are policy and research recommendations for the South African coal mining industry, covering the coordination of the critical areas of the proposed integrated strategy for the development of the coal mining industry. Such recommendations include further research into new coal mines and power stations as well as perceptions and expectations of potential investors in the industry, among others.
