Research Status of sulfoaluminate cement-based material grouting technology for strata disaster control in mining engineering

Grouting technology is an important means for controlling strata disasters and has been widely employed in mining engineering. Grouting materials are the core of grouting technology, and numerous types of grouting materials have been developed globally. Among these, the sulfoaluminate cement-based grouting material has achieved excellent results in fractured rocks reinforcement, filling, and water blocking projects due to its high stone strength and rapid growth, adjustable setting time, no sedimentation or segregation of the slurry, simplified operational requirements, and cost-effectiveness. To further promote in-depth research on the grouting technology of sulfoaluminate cement-based materials and its application in strata disaster control fields, this study reviews the research on sulfoaluminate cement-based materials and the grouting process, points out the shortcomings and prospects of current research, and presents our typical engineering application cases of sulfoaluminate cement-based grouting materials.
