Research on Division and Prevention Measures of Three Zones for Water Prevention and Control in Shouwang Coal Mine
In response to the complex hydrogeological conditions of the mine of Shanxi Yicheng Shouwang Coal Industry Co.,Ltd.,the division basis of the"three zones"for water prevention and control of 9#coal was determined through theoretical analysis and data collection.Numerical simulation and on-site verification methods were used to study the water inrush mechanism in the main areas of the 9#coal mining area(floor water threat area),as well as the advanced grouting reinforcement technology in the floor water threat area during the coal mining process.The evolution law of the stress field and plastic zone of the roof under different mining distances and the diffusion law of slurry under different grouting pressures of different grouting layers were revealed,providing a research basis for selecting a reasonable grouting pressure.The research results can provide reference for water hazard prevention and control in similar mines.
