A project health check for coal mining caompanies : case of Douglas Middelburg optimisation projectDe Wet, G.F. 30 November 2007 (has links)
The purpose of the study is to develop a project health check model to evaluate
the status of projects within the coal mining industry. The model will be based on
the Buttrick (2000) project health check model as described in his book “The
Interactive Project Workout”.
The model assesses the current “health” or status of a project. It looks at the full
project environment and uses a set of question results in an assessment of the
overall risk associated with the project. The model evaluates seven key project
success factors which include:
1. Project Plan 5. Expertise
2. Resources 6. Clear Specification
3. Ownership 7. Top Level Support
4. Justifiable Case
The model fulfils two roles:
• As a checklist, and
• As a tool to indicate where a project manager’s efforts should be directed.
This study will give an overview of the coal mining industry and the way projects
are being evaluated and prioritised. The Buttrick (2000) project health check
model will be assessed and adapted to evaluate projects within the coal mining
industry. The “new / adapted” model will be applied to the Douglas / Middelburg
Optimisation (DMO) to evaluate the health status of the project which is currently
at the end of definition (feasibility) stage within BHP Billiton Energy Coal South
Africa.
The results obtained from the new health check model showed that the DMO
project was in a healthy state with a project health check score of 47.33. It could
4
thus be concluded that the DMO project is ready to move in to the execution
phase of the BHP Billiton capital investment process.
The results obtained from the project team member participants were split into
management perception and team members’ perception. The overall health of
the DMO project between the two parties gave similar results with the team
members score of 43.76 being slightly lower than the management health score
of 45.42. The only major difference was observed on the “Communication”
project evaluation criteria where the management perspective on the
communication effectiveness was higher than that of the project team members.

Nanticoke, Pennsylvania: Impacts of the Anthracite Coal Industry: A Case StudyElias, Amber 22 May 2006 (has links)
The story of Nanticoke, Pennsylvania from 1747 to 2006 is at the same time a look into the economic, political, and social aspects of America. From the birth of the American Industrial Revolution in the eighteenth century, Nanticoke played an important role in the economic health of the country. Profits from capital investment brought great wealth to the elite of the Wyoming Valley and financiers in New York and Philadelphia. The use of immigrant labor to maintain labor costs would presage corporate use of other groups. With the change in technology and the movement of capital elsewhere, Nanticoke faced the trauma of economic hardship and the need to address the human and social cost of the loss of coal mining. The actions taken by the local leadership failed to meet the challenge. Confronting the harsh reality of possible further decline, the community of Nanticoke must take action upon a plan that holds out a possibility of stopping the hemorrhage of its decline, and perhaps even begin a recovery. The people of Nanticoke and their problems are now one being repeated elsewhere in America. The questions raised by what happened in Nanticoke lie at the core of the economic, political, and social questions facing the United States today. Corporate responsibility, quality of life, immigration, and effective urban planning are just some of the issues that Nanticoke's story poses for the rest of America.

Engineering linkages with the coal chainGrundy-Warr, Carl January 1989 (has links)
"Industrial restructuring without parallel in recent British industrial history" is how the current Chairman of British Coal, Sir Robert Haslam, has described events in that industry. Since 1960 upwards of three quarters of a million jobs have gone in the deep coal mining industry alone. Numerous studies have analysed the underlying mechanisms behind the rapid decline of the nationalised coal industry, but hitherto little attention has been paid to the national linkage effects of that decline. This thesis is an attempt to analyse the consequences of industrial restructuring in coal mining on its UK engineering suppliers. In so doing, the thesis develops into much more than an empirical case study of industrial linkage and becomes a critical analysis of state capital-private capital relations. In particular, it focusses on the shifting boundaries of state ownership in the energy sector of the 'eighties. It considers what are the main processes involved and some of the consequences for those people and places most dependent on mining related jobs for their livelihoods.

The evaluation and quantification of respirable coal and silica dust concentrations : a task-based approach / T. Grové.Grové, Tanya January 2009 (has links)
Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts that contain crystalline silica. Silica exposure is an occupational health priority even when exposure has ceased or is below the occupational exposure limit (0.1 mg/m3).
The objective of this study was to determine the individual contributions of the underground coal mining tasks to the total amount of respirable dust and respirable silica dust concentrations found in this environment. The tasks that were identified were continuous miner (CM) cutting, construction, the transfer point, tipping and roof bolting. Respirable dust sampling was conducted at the intake and return of each task, as well as at the intake and return of the section and the intake airway to the section. The five occupations that perform these tasks were also sampled to determine the personal exposure levels.
Respirable dust concentrations and small concentrations of respirable silica dust were found in the intake airway and intake of the section, indicating that the air that enters the section is already contaminated. The respirable dust-generating hierarchy of the individual tasks was: transfer point>CM right cutting> CM left cutting> CM face cutting> construction> roof bolting > tipping. For respirable silica dust the hierarchy was: CM left cutting> construction> transfer point> CM right cutting. CM face cutting, tipping and roof bolting generated concentrations of below quantifiable levels. The personal exposures also differed and the eM and stamler operators had the highest exposure to respirable dust (3.417 ± 0.862 mg/m3) and respirable silica dust (0.179 ± 0.388 mg/m3) concentrations, respectively. Recommendations have been included for lowering the respirable dust and silica dust concentrations that are generated and that the workers are exposed to underground. / Thesis (M.Sc. (Occupational Hygiene))--North-West University, Potchefstroom Campus, 2010.

The impact of legislation and other factors on the safety performance of Australian coal minesParkin, 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.

Vlastnosti rekultivovaných povodí a jejich vliv na chemismus odtékající vody / Properties of reclaimed post mining catchments and its effect of run of chemistryHurychová, Renata January 2013 (has links)
After the end of hydric recultivation from the monitored source of watering, artificially bulit-up lakes are fed with the water from their own basin. This water is not so systematically monitored as compared to the water from the new lake and the sources of its filling. This thesis summarizes findings about the developement of artificially made basin in the mining area and explains differences between various basins. Further, this work deals with the characteristics of water feeding lake "Chabarovicke jezero (Milada)", which was bulit-up during hydric recultivation of the mineshaft in the soft-coal quarry Chabarovice. Monitored basins have different area, slope, vegetation coverage and distribution of dissolved compounds. These factors have significant impact on the character of the water in affluents. We found out, that affluents from the own basin have high concentration of dissolved compounds resulting in the unwanted enrichment of the lake. Big problem was the high concentration of sulphates and nitrates, which in all affluents, except for one, exceed tolerated limits for surface waters. In the course of time, concentrations of dissolved compounds go down. Particular affluents differ between each other and the main impact on the water characteristic is the slope, exposition and area.

A qualitative analysis of post-traumatic stress disorder experiences at the Slater Coal Mining industryDumakude, 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.
