“…Scholars have mostly focused on the quantitative analysis of uncertainty parameters. The commonly used quantitative methods include the data quality indicator method, Bayesian statistics, fuzzy theory, analytical uncertainty propagation, and probability method [90] . The application of Monte Carlo simulation after carbon emission accounting is considered a relatively complete process of GHG emission estimation [91] .…”

China is the world’s largest carbon emitter and coal de-capacity is a policy with immediate and substantial CO2 reduction effects. However, the carbon emission reduction and health co-benefits arising from the coal de-capacity are often ignored. Here, we assessed the carbon emission reductions and quantified the health co-benefits from coal de-capacity based on an analysis of the spatial and temporal distribution characteristics of the mine closures and phase out during 2016–2022. Our findings show that China had closed/phased out a total of 4027 mines with a total de-capacity of 8.75 × 108 t, spatially concentrated in Southwest and North China from 2016 to 2022. The coal life cycle emitted 1859 million t of carbon during the coal de-capacity. Importantly, 11,775 premature deaths were avoided during 2016–2022 due to reduced PM2.5 exposure as a result of coal mining. This study highlights the significant effects of coal de-capacity on carbon reduction and health co-benefits in China and provides scientific evidence and data to support the achievement of the sustainable development goals and the ‘dual carbon goals’.

“…Scholars have made some achievements in the study of overlying strata structure; these proposals and the obtained results are largely related to a single working face and multiple working faces are relatively unexplored. In addition to this shortcoming, all previous studies have collectively shown that there is vertical zoning and horizontal zoning in the mining strata of the working face [18]. In terms of rock mechanical structure, cantilever beam theory, pressure arch theory [19,20], hinged rock block hypothesis [21], and key stratum and voussoir beam theory [22,23] are the main contributions.…”

The geological environmental damage caused by coal mining has become a hot issue in current research. Especially in the western mining area, the size of the mining working face is large, the mining intensity is high, while the surface movement and deformation are more intense and wider. Therefore, it is necessary to effectively monitor the surface using appropriate means and carrying out research on the overlying strata structure of the stope. In this paper, by using advantages of various subsidence monitoring technologies and the technical framework of the Internet of Things (IoT), a “space–air–ground” integrated collaborative monitoring network is constructed. The evolution law of overlying strata structure is studied based on discrete element simulations and theoretical analysis. Furthermore, a discrete element mechanical parameter inversion method is proposed. The main results, using numerical simulations, are as follows: The mean square error of monitoring surface subsidence is 33.2 mm, the mean square error of mechanical parameter inversion is 13.4 mm, and relative error is as low as 3.8%. The surface subsidence law of adjacent mining under different working face widths and interval coal pillar widths is revealed. The Boltzmann function model of surface subsidence ratio changing with width–depth ratio and the calculation formula of width reduction coefficient of adjacent mining working face are inverted. The critical failure width of the interval coal pillar is determined as 20.5 m. Based on the theory of “arch–beam” structure and numerical simulation results, the overlying strata structure model of adjacent mining in the mining area is constructed. The research results can provide technical support or theoretical reference for mining damage monitoring, subsidence control, and prediction in western mines.
