The Influencing Factors of Grouting Diffusion Radius in XUhui Aquifer and Grouting Optimization Scheme
In the field of coal mine water prevention and grouting treatment,the reinforcement and renovation of the top and bottom plates are commonly faced with the problems of high grouting consumption and high cost of grouting materials.This study comprehensively analyzes the key factors affecting grouting,including grouting hole structure,stratum location,rock proper-ties,water output,water quality composition,and grouting pressure,with the aim of increasing the diffusion radius of grou-ting holes to address technical challenges such as excessive water flow in drilling holes,insufficient absorption of grouting ma-terials,and limited diffusion radius of grouting.The research results indicate that optimizing the factors affecting grouting to in-crease the diffusion radius can effectively reduce grouting costs and significantly enhance the grouting effect in the Xuhui aqui-fer.
