Abstract: The technology of gob-side entry retaining is a highly efficient roadway laying and mining technology, the safety and
effectiveness application of which is of great significance for improving the comprehensive benefits of mines. With this as a
starting point, this paper carried out analysis and investigation on the application of support in gob -side entry retaining in
thickened coal seams. Based on the specific engineering practice and the overall analysis of the technology of gob-side entry
retaining, the design analysis of the actual application of gob-side entry retaining was carried out, and its application effect was
detected and analyzed. The results showed that the designed scheme achieved effective support for the surrounding rocks of the
roadway and improved the use efficiency.

Key words: coal mine; thickened coal seam; gob-side entry retaining; support technology
