“…The text mining results (Table 4 and Figure 3) indicate that the victims experienced discriminatory damage after the incident. The text mining analysis for each stakeholder revealed that the damage from the oil spill in Taean incorporated all aspects of sustainability [32,33], including the physical aspects [34,35], the social aspects of the village community, the environmental aspects of disaster prevention, and the economic aspects of the livelihood loss of residents. Additionally, haenyeos mentioned that they suffered significant damage to their physical health.…”

Environmental pollution causes severe damage to local communities, which is perceived differently by different victims, that is, the damage is discriminatory. However, previous studies have not focused on this aspect. Here, we explored the perceptions of different victims of the Hebei Spirit oil spill incident of Korea. Additionally, we explored the importance of considering discriminatory aspects of damage when planning recovery governance. The damages from the oil spill were analyzed using a text mining technique for each subject based on factor analyses. Women and residents older than 60 years were interested in the social relations of the village community; residents in their 40s, who were raising children and teenagers, were interested in the economic aspects; boat fishermen, who had discontinued fishing to participate in the pollution response activity in the early stages of the incident, were interested in disaster prevention; and women divers were interested in health issues. Hence, restoring the economy and environment and reversing indirect social damages are essential for recovery from pollution damage. Furthermore, governance for recovery must not exclude specific victims based on the discriminatory aspects of damages. A political process is necessary to secure the validity of governance and alternatives by involving different victim groups.

“…The usage of this technology can process coal gangue and fly ash, two solid forms of waste from coal mines, and solid waste around cities while replacing coal resources under buildings (structures) such as villages, railways (roads) and overlying aquifers, and on floor pressurized water (referred to as "three under one on"). This is a type of scientific coal mining technology that is in line with the ecological mine development model of "lucid waters and lush mountains are invaluable assets," advocated by President Xi Jinping, with great promotion and application prospects (Hu and Guo, 2018;Qian et al, 2018;Wang et al, 2018;Dong et al, 2019;Ma et al, 2019;Wang et al, 2020a;Dong et al, 2020;Liu et al, 2020;Ju et al, 2021). To date, three kinds of filling mining technology approaches have been developed in China: solid filling technology (Miao et al, 2010), paste filling technology (Zhou et al, 2010;Sun et al, 2018;Wu et al, 2020a), and high-water filling technology (Feng et al, 2010;Chang et al, 2018).…”

Experimental Study on the Compaction and Deformation of Filling Gangue by Reducing Waste Gangue for Filling Mining

et al. 2021

The coal mining technology of fully mechanized solid filling is an efficient and green mining method that integrates “sediment reduction” and “emission reduction.” However, the discharge of wasted gangue and surface subsidence are controlled by the amount of wasted gangue used in filling mining and the compaction rate of gangue filled into a goaf, respectively. To increase the consumption of wasted gangue and reduce surface subsidence, mixed gangue composed of equal-quality washed gangue and crushed gangue is proposed as a raw material for solid filling on the basis of gradation theory. Next, a screening experiment was performed to analyze the grain gradation of different specimens, and a compression experiment was executed to compare and analyze the compression characteristics. The results show that the nonuniformity coefficient of mixed gangue is 55.2 and the curvature coefficient is 1.53, which significantly improve the grain gradation of washed gangue. The degree of relative compaction of mixed gangue is 1.226, which is significantly lower than that of washed gangue, which is 1.33. The deformation modulus of mixed gangue is 23–135 MPa, which is better than that of washed gangue (26–100 MPa), indicating that the compressive resistance of mixed gangue is significantly improved. The case study of the Tangkou mine suggests that mixed gangue greatly promotes the consumption of wasted gangue and can effectively control the surface deformation.

“…Tailings can contain residual (non-)metalliferous minerals that can be valorised due to less efficient processing technologies of the past or because the contained minerals were not exploitable but are used as RMs in modern technologies [16][17][18][19][20][21]. Indeed, there are efforts to improve tailingsrelated safety by monitoring or the removal of contaminants for instance [22][23][24]. However, tailings still pose a risk to human health and life, the environment, and the economy; for instance by acid mine drainage (AMD) as a result of the oxidation of sulphide minerals in contact with air and water, heavy metal-laden dust emissions or structural collapse due to the often poor construction of TSFs in the past [15,25,26].…”

Mapping the raw material (RM) potential of anthropogenic RMs, such as tailings, requires a comprehensive assessment and classification. However, a simple procedure to quickly screen for potentially viable RMs recovery projects similar to reconnaissance exploration of natural mineral RMs is missing. In this article, a quick and efficient approach to systematically screen tailings storage facilities (TSFs) is presented to evaluate if a particular TSF meets the criteria to be assessed in a more advanced study including costly on-site exploration. Based on aspects related to a TSF’s contents, physical structure, surroundings, potential environmental and social impacts, and potentially affected stakeholders, it guides its user in compiling the information at local scale in a structured manner compliant with the United Nations Framework Classification for Resources (UNFC). The test application to the TSF Bollrich (Germany), situated in a complex environment close to various stakeholders, demonstrates that a quick and remote assessment with publicly accessible information is possible. Since an assessment of tailings under conventional classification codes from the primary mining industry neglects relevant aspects, it is concluded that tailings should be considered as anthropogenic RMs. The developed screening approach can help to create a TSF inventory which captures project potentials and barriers comprehensively.
