Effective safety supervision plays a crucial role in ensuring safe production within coal mines. Conventional coal mine safety supervision (CMSS) in China has suffered from the problems of power-seeking, excessive resource consumption and poor timeliness. This paper aims to explore the Internet+ CMSS mode being emerged in China.

The evolution of CMSS systems underwent comprehensive scrutiny through a blend of qualitative and quantitative approaches. First, evolutionary game theory was used to analyze the necessity of incorporating Internet+ technology. Second, a system dynamics model of Internet+ CMSS was crafted, encompassing a system flow diagram and equations for various variables. The model was subsequently simulated by taking the W coal mine in Shanxi Province as a representative case study.

It was revealed that the expected safety profit from the Internet+ mode is 296.03% more than that from the conventional mode. The precise dissemination of law enforcement information was identified as a pivotal approach through which the Internet+ platform served as a conduit to foster synergistic collaboration among diverse elements within the system.

The outcomes of this study not only raise awareness about the potential of Internet+ technology in safety supervision but also establish a vital theoretical foundation for enhancing the efficacy of the Internet+ CMSS mode. The significance of these findings extends to fostering the wholesome and sustainable progress of the coal mining industry.

This research stands out as one of the limited studies that delve into the influence of Internet+ technology on CMSS. Building upon the pivotal approach identified, to the best of authors’ knowledge, a novel “multi-blind” working mechanism for Internet+ CMSS is introduced for the first time.

The purpose of this paper is to construct historical perceptions of coal use in India and Japan in different historical time periods through the process of analyzing the narratives and discourses in academic, media and trade literatures.

In terms of methodology, this paper will utilize discourse theories/analysis and interpretive history to study the subject matter. In this paper, specific literatures on energy as well as general literatures on themes like technology are utilized.

The finding of the paper is that discourses and narratives about coal energy for example are constantly negotiated, constructed and then deconstructed again to fit and adapt to new realities, including the availability of newer technologies or priorities and concerns about the environment.

The research implication and originality of the paper is to demonstrate empirically the idea of the existence of narrative communities debating the use of coal energy in India and Japan. It highlights the communities of stakeholders interested in coal energy resource. The practical application and value of the ideas is the intellectual process of categorizing various contemporary narratives about coal energy use specific to two of the largest consumers and importers of coal in Asia. Through historical narratives of its past and recent coal use, the role and function of coal in the overall energy mix of India and Japan are instructive. The research limitation lies in its non‐quantitative nature and reliance on a combination of academic and trade secondary sources.

Indiana is listed among the top ten coal states in the USA and annually mines about 35 million short tons (million tons) of coal from the vast reserves of the US Midwest Illinois Coal Basin. The implementation and commercialization of clean coal technologies is important to the economy of the state and has a significant role in the state's energy plan for increasing the use of the state's natural resources. Coal is a substantial Indiana energy resource and also has stable and relatively low costs, compared with the increasing costs of other major fuels. This indigenous energy source enables the promotion of energy independence. The purpose of this paper is to outline the significance of clean coal projects for achieving this objective.

The paper outlines the clean coal initiatives being taken in Indiana and the research carried out at the Indiana Center for Coal Technology Research.

Clean coal power generation and coal for transportation fuels (coal‐to‐liquids – CTL) are two major topics being investigated in Indiana. Coking coal, data compilation of the bituminous coal qualities within the Indiana coal beds, reducing dependence on coal imports, and provision of an emissions free environment are important topics to state legislators.

Lessons learnt from these projects will be of value to other states and countries.

Coal is the basic energy and essential resource in China, which is crucial to the economic lifeline and energy security of the country. Coal mining has been ever exposed to potential safety risks owing to the complex geologic environment. Effective safety supervision is a vital guarantee for safe production in coal mines. This paper aims to explore the impacts of the internet+ coal mine safety supervision (CMSS) mode that is being emerged in China.

In this study, the key factors influencing CMSS are identified by social network analysis. They are used to develop a multiple linear regression model of law enforcement frequency for conventional CMSS mode, which is then modified by an analytical hierarchy process to predict the law enforcement frequency of internet+ CMSS mode.

The regression model demonstrated high accuracy and reliability in predicting law enforcement frequency. Comparative analysis revealed that the law enforcement frequency in the internet+ mode was approximately 40% lower than the conventional mode. This reduction suggests a potential improvement in cost-efficiency, and the difference is expected to become even more significant with an increase in law enforcement frequency.

To the best of the authors’ knowledge, this is one of the few available pieces of research which explore the cost-efficiency of CMSS by forecasting law enforcement frequency. The study results provide a theoretical basis for promoting the internet+ CMSS mode to realize the healthy and sustainable development of the coal mining industry.

The dilemma falls within the Change Management, Leadership, Organizational Development subject areas. In addition, the case highlights typical issues in “green” or sustainable supply chain, corporate social responsibility and sustainability courses.

The target audience is includes post-graduate diploma-level or master’s level students, such as in Masters in Business Administration.

The case focuses on the dilemma that Phiwokuhle Mhlangu in Mpumalanga, South Africa, faced when his company’s board had not signed off on capital expenditure to improve his colliery’s clean coal technology initiatives. He had to influence his colleagues’ mindsets to adapt to changes in the environment. The case highlights the global coal landscape and South African mining industry’s challenges in terms of infrastructure and strained labour relations, as well as the focus of the South African Government to enhance alternative energy resources. Although a clear business case for investment in clean coal technologies was evident, Mhlangu could still not persuade his colleagues to support these initiatives. A different approach was required […]

The learning objectives in this case are: gaining insight into the dilemmas of sustainability in coal mining by exploring various interest groups in difficult sustainability situations and enhancing understanding of getting a buy-in from various stakeholders when leading change in the coal-mining sector.

A teaching plan and particular teaching methodologies is included. The two learning outcomes are posed as questions for groups to discuss and model answers are provided and to relevant literature.

The case study deals with financial and strategic appraisal of a unique coal-to-liquid project. India imported about two thirds of its crude oil requirements resulting in huge outflow of precious foreign exchange. As a result, it became necessary for the country to look for alternative sources of energy. The coal-to-liquid (CTL) technology of coal gasification offers a credible alternative source of fuels as proved by Sasol of South Africa. The Government of India short-listed Global Synfuels Company (name changed) as one of the selected few companies to build a CTL project. While the project is strategically important to the company and highly desirable for the country, there are serious doubts about the commercial viability of the project because of which the company is in dilemma whether to go ahead with the project. The case study presents this decision dilemma in a very interesting way and will be useful for teaching courses in corporate finance and strategic management.

The case can be used to engage participants to make a SWOT analysis for a new business opportunity, discuss environmental and financial issues facing a company, use DCF techniques to evaluate the project viability, carry out scenario analysis of the project to the changes in variables as well as challenge the participants to generate strategies for the success of a new project. Participants would also develop a better understanding of: environmental issues involved in CTL projects and new technologies to deal with such issues; and the employment impact of large projects such as the CTL.

Sustainable development (SD) in developing countries is mentioned as one of the main aims of the Kyoto protocol's clean development mechanism. However, in the present context, uncertainty prevails to whether the (CDM) is actually procuring its aims in terms of achieving SD and to what extent. Chile, which has an open market economy, could risk becoming “locked” into a carbon intensive future, due to the recently discovered coal reserves and plans of large utilities to move to coal technology and not necessarily clean‐coal technology. The aim of this paper is to assist Chile in finding ways of encouraging technology transfer of energy technologies that would contribute to a low‐carbon sustainable energy development.

In order to be able to identify potential CDM projects facilitating SD in developing countries, through technology transfer from developed ones and, thus, to formulate a series of possible investment strategies with a SD component, it is crucial to establish a clear understanding of the host country's needs and priorities and the suitable energy technologies to meet these needs.

This paper presents results obtained from an elaborated stakeholders' assessment on Chile's high priority energy needs, sustainable energy technologies fulfilling these needs and opportunities and barriers related with the implementation of these technologies in the particular market.

The paper provides useful results that could facilitate Chile's designated national authority as well as future project investors to put on the map the most suitable sustainable energy technologies, based on the country's SD needs and priorities, to transfer and implement via CDM. The above is particularly important for Chile since recent coal discoveries could risk becoming “locked” into a carbon intensive future.

In China there are large amounts of coal located underneath buildings. In this article the severity of the problem is studied, and the characteristics of the mining technology used for the extraction of coals under buildings are described. Based on the comprehensive analyses of the abundant literature, separated bed grouting, backfill mining, Partial Mining and homonic mining technology, are the main mining technologies that exist for extraction of these coals. At the same time, the necessary measures for protecting the buildings are also considered. In particular, the authors have analysed the development of these mining technologies and concluded that the waste filling will be the focus of development, and that the main developing technologies of the filling mining method should be further perfecting the separated bed filling, strip mining and strenthening the anti-deformation of building.
