The application dilemmas and improved technical path of bolt support in confined spaces in non⁃coalunderground mines were thoroughly investigated. Non⁃coal underground mines often feature complex orebody occur⁃rence conditions, and confined spaces are commonly encountered during thin orebody mining and up⁃hill cutting, lead⁃ing to significantly reduced bolt installation efficiency and support effectiveness, which makes traditional bolt supportdifficult to apply effectively. The characteristics of confined spaces in non⁃coal underground mines and their impact onbolt support were analyzed, revealing that insufficient space height, poor equipment adaptability, mismatched platestructure and stress, and difficulties in pre⁃tension control technology were the main factors restricting bolt supporteffectiveness. Research progress in bolt support was systematically reviewed from both key technologies and engineeringapplication challenges. To address the application dilemmas of bolt support in confined spaces in non⁃coal undergroundmines, an integrated improved technical path was proposed, including drill rig miniaturization, innovative special⁃shapedplates, and precise pre⁃tension control technology. The future development direction of support technology in non⁃coalunderground mines was outlined, emphasizing that improved equipment adaptability, enhanced control precision, andbreakthroughs in material performance can provide comprehensive technical support for deep resource developmentand continuously improve the safety and efficiency of non⁃coal underground mining.
