“…Jia et al (2022) combined field monitoring data with numerical simulation to achieve deformation and failure of a goaf over time and made a comprehensive evaluation of its stability [17]. Tao et al ( 2022) selected 15 indexes to analyze the site selection for the development and utilization of abandoned goafs, obtained the weight of the indexes by using a triangular intuitionistic fuzzy number and then determined the optimal site-selection decision-making framework by using the multi-criteria decision theory [18]. Dai et al (2022) established an evaluation system for the stability of a goaf based on AHP and conducted a case study by obtaining evaluation cloud maps through cloud models.…”

Mineral resource-based cities have formed a large number of goafs due to the long-term mining of coal. It is of great significance to make full use of the abandoned land resources above the goaf to promote the transformation and development of resource-based cities. In order to avoid the threat of surface residual deformation to the proposed construction project, it is an urgent problem to obtain the stability results of the construction site accurately. First of all, based on the principles of relevance, hierarchy, representativeness and feasibility of index selection, 10 indexes are selected to construct the stability evaluation index system. Then the subjective weight and objective weight of evaluation indexes are determined based on improved AHP, rough set and CRITIC methods, which improves the accuracy of the determination of the index weights. In addition, the membership degree of each index is determined using the cloud model. Finally, the stability grade can be obtained according to the maximum membership degree theory. The above researches are applied to evaluate the stability of the Mianluan expressway construction site, and the results show that the stability level of the study area is not uniform and that there are two states: stable and basically stable. Finally, a sensitivity analysis of the subjective weight of each index is carried out, the index stopping time has the highest sensitivity to weight (12.44%), which is far lower than the corresponding weight change rate of 100%, indicating that the determination of weight is scientific and reasonable. These things considered, the reliability of the evaluation result is indirectly verified according to the field leveling. This research can provide a reference for the effective utilization of land resources above an old goaf.

“…Görtz et al [5] presented criteria for evaluating suitable PSHP sites based on rivers and coastal areas, but both papers lacked economic items. Tao et al [6] used an abandoned mine as a reservoir to utilize the PSHP site and 15 evaluation indicators for site selection were built. Menéndez et al [7] also conducted an analysis to utilize an abandoned mine as an underground reservoir for PSHP.…”

As the proportion of new and renewable energy increases, power control demands are becoming more frequent due to variability in power generation. As a complementary means against this, the pumped storage hydropower plants (PSHP) are attracting attention as energy storage systems (ESS), but it has high construction costs. Therefore, this study aims to improve the economic feasibility by developing the evaluation model of the existing infrastructure into an upper/lower dam suitable for PSHP. The concept of upper dam capacity is newly defined, and the evaluation index is constructed using normalization. A new evaluation system is presented for five factors: environment, stability, energy, capacity, and economy. Finally, it is tested in the pilot area in Korea. Several candidates, including the PSHP in operation, are found to have been distributed with higher scores. These results will help to satisfy the selection of candidates during the preliminary feasibility study phase, and programming them will enable more accurate and rapid assessment.

“…Currently, there are some studies on UPHES, with a main focus on technical feasibility [19][20][21][22], environmental impact [23,24], and economic analysis [25,26]. However, limited attention has been paid to site selection [27,28], which is vital to the implementation of UPHES in old mines. Unlike conventional pumped storage projects, site selection for UPHES projects in old mines requires additional consideration of the geological and hydrogeological conditions of the mining area, which may even be decisive or restrictive.…”

However, the proposed framework is a traditional one-step assessment that may weaken the impacts of geological and hydrogeological conditions.…”

In the context of carbon neutrality, the phase-out of coal from the energy structure has resulted in numerous old coal mines that possess abundant underground space resources suitable for underground pumped hydroelectric energy storage (UPHES). Site selection and estimation of potential are critical to the planning and implementation of UPHES in old coal mines. This paper introduces a two-step site selection concept, including a screening assessment followed by a comprehensive assessment, to determine suitable locations for UPHES. The screening indicators in the screening assessment comprise geological features, mine water disasters, and minimum installed capacity, while the analytic hierarchy process (AHP) is applied in the comprehensive assessment. Additionally, coal mines in Henan Province are preliminarily screened through the screening assessment and the potential for UPHES is thoroughly investigated. The estimated volume of the drifts and shafts in old coal mines is approximately 1.35 × 107 m3, while in producing coal mines, it is around 2.96 × 107 m3. Furthermore, the corresponding annual potential for UPHES is 1468.9 GWh and 3226.3 GWh, respectively. By consuming surplus wind and solar power, UPHES is able to reduce 4.68 × 105 tonnes of carbon dioxide (CO2) emissions. The study provides preliminary guidance for policy-makers in developing UPHES in old coal mines.
