Abstract: The principle of retaining wall technology along the goaf in coal mines was analyzed, and the technological process of
applying flexible formwork support technology for retaining walls along the goaf in the working face with large mining height was
elaborated. Targeted reinforcement measures were developed based on dynamic monitoring of the strength of masonry walls. The
study shows that the flexible formwork support technology for retaining walls along the goaf is suitable for the working face with large
mining height and thick coal seam. The application of this technology has improved coal recovery rate, reduced roadway excavation
volume, and achieved green coal mining. It has the potential for promotion and application in coal mines with suitable conditions.

Key words: working face with large mining height; retaining walls along goaf; flexible formwork support; technological process;
