The Sijiaying Iron Mine (Hebei Iron and Steel Group, China) is Asia's biggest iron mine, and produces more than 70 million tons of tailing slurry annually, with a mass concentration of 20% [1]. As villages and farmland surround the mine, building a conventional tailings impoundment (CTI) near the iron mine will require an area of 4.2 km 2 , the demolition of three villages, the relocation of 1,000 people, and a total investment of more than 500 million CNY. Furthermore, wastewater, gas, and residue will cause serious pollution issues, making it a significant danger source if the dam were to seep or break [2]. Under the context of farmland protection in China and the downturn in the iron ore market [3][4], such a large land expropriation and investment is impossible.In the past 20 years, paste tailings have been proved to be an environmentally friendly, cost-effective backfill and tailings disposal method [5]. Fourie [6] analyzed the advantages of paste and thickened tailings technology Pol. J. Environ. Stud. Vol. 26, No. 4 (2017), 1855-1863 AbstractThis paper evaluates the feasibility and stability of the construction of a super-large-scale filtered tailings storage facility on coal-mining subsidence land. Properties of the coal gangue were analyzed by laboratory tests and change laws of the land subsidence were observed in the field. Comparisons of slope stability between the super large-scale filtered tailings storage facility and conventional tailings impoundment in normal, flooded, sustained rainfall, and strong earthquake conditions were conducted using Slide software. The results show that the filtered tailings storage facility has less chance of failure, lower seepage probability, and smaller impact scope than conventional tailings impoundment. With little free water in filtered tailings, the average slope safety factors of filtered tailings storage are as high as 1.78 in normal, 1.73 in flood, 1.18 in sustained rainfall, and 1.11 in a magnitude-8.0 earthquake. As an environmentally friendly, costeffective chain-cutting disaster mitigation measure, filtered tailings disposal shows great advantages in reducing tailing emissions, dam construction scale, and operational costs, improving water conservation, dam stability, and service life.Keywords: super large-scale, filtered tailings storage facility, subsidence land, coal gangue, filtered tailings disposal, disaster chain, disaster mitigation *e-mail: shuaige@csu.edu.cn DOI: 10.15244/pjoes/68876 1856 Zhang D., et al. in stopes backfilling. An application of the paste tailings disposal on the surface in the Bulyanhulu mine has been reported by Theriault [7]. With little or no free water bleeding in nature ( Fig. 1), paste tailings can be disposed of on the surface with low failure risks compared with CTI [8]. With a mass concentration of 68%, the paste tailings slurry of Sijiying is still susceptible to liquefaction and the paste tailings dam is still a big dangerous source, especially in rain regions [9].With the development of dewatering technolo...

“…A disaster chain is defined as a sequence of unfortunate events, each of which is the main cause of the next episode event, and has been widely used in disaster analysis for earthquakes, floods, and mining [17]. Peng et al [18] found that mining groundwater, land subsidence and earth fissures occur in a sequence and constitute a disaster chain with respect to urban hazards in Xi'an. Gao et al [19] analyzed the disaster chains induced by mining and proposed a series of prevention measures according to the chain-cutting disaster mitigation technology.…”

Abstract:In order to evaluate the superiority of a filtered tailings storage facility (FTSF) to conventional tailings impoundment in the southern rainy regions of China (SRRC), the tailings slurry leakage and pollution accident occurring at the wet tailings dam (WTD) of Yinshan were analyzed, the properties of the tailings were tested in a laboratory, and the possibility of tailings liquefaction was evaluated. Comparisons of the slope stabilities of the filtered tailings dam (FTD) and WTD in normal operation, flood, continuous rainfall, and earthquake situations were simulated using the Slide software. The results show that the FTD has less chance of seepage, lower failure probability, and limited potential destructiveness than the WTD with average slope safety factors of 2.120 for normal operation, 1.919 for flooding, 1.204 for continuous rainfall, and 1.724 for a magnitude-6.0 earthquake. The disaster chain model of the WTD of Yinshan belongs to the bursting and slippage chain. As the most safe and effective active prevention measure, the FTSF has the advantages of saving water, protecting the environment, improving its stability in flood and rainfall situations, and reducing the dam failure probability and potential losses, which is greatly applicable to the SRRC.

“…Unfortunately, these dry western areas are highly sensitive to human activity and climate change, raising concerns about the sustainability of water supplies and the risk of soil and water quality degradation (Li, 2016;Li, Tian, Xue, & Wu, 2017a;Wu et al, 2017). Eastern and northern China, for example the North China Plain and the Su-Xi-Chang Region, are also seeing water resource overexploitation and degraded water quality, leading to seawater intrusion, ground subsidence and ground fissures (Cao, Han, & Moser, 2013;Guo et al, 2015;Kang, Wang, & Du, 2017;Peng, Qiao, Leng, Wang, & Xue, 2016b;Peng, Sun, Wang, & Sun, 2016a). The situation in southern China is also not encouraging.…”

a school of environmental science and engineering, chang'an university, Xi 'an, china; b Key laboratory of subsurface Hydrology and ecological effects in arid region of the ministry of education, chang'an university, Xi'an, china ABSTRACT Water resources are the basis for the sustainable development of China. However, the country is currently facing alarming waterrelated problems associated with its fast economic development and climate change. This editorial introduces briefly the status of its water resources research at the national level and the researcher level. It also introduces the research reported in this thematic issue to highlight its role in addressing flood and water-scarcity issues, improving water management in inland plains and supporting the sustainable development of the country. Finally, some further recommendations for improving water resources research in China are offered.
