Abstract
Hydrological issues in roof induced by coal seam mining have become increasingly prominent,posing significant challenges to coal mine safety production.To address this,multiple research methods including on-site observation,theoreti-cal analysis,and similar material simulation were employed to analyze the hydrogeological parameters of the roof affected by mining in the Xingsheng Hongfa Coal Mine.A dynamic calculation method for mine water inflow,termed the"Mobile Large-Well Method,"was proposed based on the evolution of hydrogeological parameters.By constructing a"Mobile Large-Well"model,the dynamic prediction of mine water inflow was achieved and validated through a case study at the mine.The results indicate that during coal seam mining,the permeability of the roof gradually increases with the extent of mining-induced damage,accompanied by an intensified decline in water levels.The calculation results of the"Mobile Large-Well Method"significantly outperformed those of traditional methods.Compared to the average relative error of 140.7％from traditional analytical methods,the application of the new method reduced the error to 88.7％.The research findings provide robust sup-port for coal mine safety production and hold significant implications for preventing water hazards in coal mines and ensuring operational safety.关键词
