Industrial symbiosis associated with the eco-industrial parks is the cooperative activities between businesses to optimize using of inputs and outputs such as raw materials, energy, water, waste materials, etc. in the orperation of businesses. In the industrial symbiosis model, the overall benefits of the symbiosis activities are more than the ones when working individually. Applying the model could help to reduce the demand of raw materials and increase the waste that be treated – an important part of the circular economy model. The coal mining industry includes many different stages from exploration, exploitation, processing, and trading. Each stage could be performed by different businesses which could corporate with each other. Besides the contributions to the socio-economic development, the industry also emits lots of waste into the environment to cause environmental pollution that needs to be treated. The paper summarizes the theoretical basis of the industrial symbiosis, the circular economy and clarifies the relationship between the industrial symbiosis, the circular economy and the sustainable development goals. From analyzing some typical situations of industrial symbiosis activities in Vietnamese coal mining industry; analyzing some characteristics and potential application of industrial symbiosis in the industry, the paper proposes the model of industrial symbiosis for Vietnamese coal mining industry. The paper also proposes some solutions to promote symbiotic activities in the industry.

Workplace safety is of paramount importance in industries such as coal mining, where accidents and occupational illnesses can result in significant human and economic costs. This study aims to develop an action plan to improve safety standards at Duong Huy Coal Company from 2021 to 2025. A comprehensive survey involving 93 safety managers and 379 workers from various production sites was researched to gather insights and opinions on safety priorities. Focus group discussions and expert consultations were employed to assess the current safety situation, identify challenges, and develop coherent safety solutions. Based on the survey results, the proposed action plan focuses on the following objectives: reducing workplace accidents by 20-25% annually, progressing towards zero accidents in the following years, and increasing productivity and benefits for both workers and the company. The plan also emphasizes the role of company leadership in widely communicating their commitment to safety and the need for individual units within the company to proactively plan, budget, and implement safety measures following their functions and responsibilities. Collaboration with relevant state agencies, mass mobilization campaigns, and the application of science and technology in safety and occupational health will further contribute to the enhancement of workplace safety at Duong Huy Coal Company.

The circular economy is the economic model that has been applied for a long time in the world. This model is applied at all three levels: micro (enterprise-level), intermediate (industry level, industrial zone level), and macro-level (local level, regional level, or national level). Vietnamese Coal Mining Industry has been having important contributions to the socio-economic development of Vietnam. However, this industry also causes lots of issues about environmental pollution. In the context of resource depletion, environmental pollution and the cost of exploiting and processing increases with the deep exploiting process; the tastes of utilizing resources, minimizing environmental pollution, and creating more value-added for this industry are inevitable requirements. Because of the tasks, applying the circular economy model into this industry (both intermediate and micro-level) is the urgent solution for the sustainable development of the Vietnamese Coal Mining Industry. The paper uses a combination of research methods such as theoretical research, case study research, statistical data analysis, etc., to propose the circular economy model for the Vietnamese Coal Mining Industry and some solutions to deploy this model into the industry's operations towards sustainable development.
