Abstract:
In order to clarify the characteristics of coal mine water hazard accidents and the development process of water prevention and control in China from 2008 to 2025, water hazard accidents with casualties occurring in Chinese coal mines during this period were investigated, analyzed, and forecasted. Meanwhile, based on the CNKI database, the research progress in the field of coal mine water prevention and control in China was systematically described using bibliometric tools. The results are shown as follows. (1) Through the analysis of 144 water hazard accidents with casualties (resulting in 823 deaths), the spatiotemporal distribution, types of water sources, and locations of water inrush in Chinese coal mines were revealed. It was found that North China and Southwest China are high-incidence areas. Goaf water is identified as the main water source, and heading faces are the most frequent accident sites. (2) The rescue durations of 107 water hazard accidents with casualties in China were tracked and investigated. The rescue work is characterized by extremely uneven time consumption, and most rescue operations require a relatively long duration. (3) An ARIMA (Autoregressive Integrated Moving Average) model was constructed and applied to predict the number of coal mine water hazard accidents in China over the next three years. The prediction results indicate that the number will remain stable at 1-2 accidents per year. (4) The keywords in the literature on coal mine water prevention and control in China can be divided into nine major clusters. The keywords "geophysical prospecting" and "water-conducting channel" appear most frequently. "Geophysical prospecting" and "advanced detection" constitute the two largest clusters among all. Intelligent monitoring and early warning of water hazards have become the newest research focus. (5) Five major contradictions in the field of coal mine water prevention and control in China were summarized and analyzed, and corresponding solutions were proposed.
