Description
Summary:China’s coal mines face very complicated hydrogeological conditions and are affected by many complex water hazards. Based on the condition of the coal seams and an analysis of regional hydrogeological and geological conditions, China's coal-producing regions have been divided into six major hazard regions. This paper summarizes the filling conditions and main types of mine water hazards for these six hazard zones. Then, the most common types of water hazards in China’s main coal mining areas (in northern and northwestern China) are analysed. North China’s coalfields face a relatively high risk of water hazards due to the fractured karst aquifers below the coal. Coal mining in the northwestern region is affected by sandstone aquifers above the coal seam, which creates a diverse array of water hazards. This paper illustrates the main characteristics of water hazards in China’s coal mines, and demonstrates the impact of water hazards in China’s coal mines. It also provides a reference for decisions related to coal industry planning and water control technology.
