摘要:
深入探讨了非煤地下矿山受限空间锚杆支护应用所面临的困境及改进技术路径。非煤地下矿山矿体赋存条件复杂，薄矿体开采、切割上山等情况产生的受限空间普遍存在，导致锚杆安装效率与支护效果显著下降，使得传统锚杆支护难以有效应用。分析了非煤地下矿山受限空间的特点及其对锚杆支护的影响，得出空间高度不足、设备适配性差、托盘结构和受力不匹配及预紧力控制技术困难等问题是制约锚杆支护效果的主控因素。从关键技术及工程应用挑战两方面，系统综述了锚杆支护方面的研究进展。针对非煤地下矿山受限空间锚杆支护应用困境，提出了包括钻机小型化、异形托盘创新及预紧力精准控制技术等在内的集成化改进技术路径。展望了非煤地下矿山支护技术的未来发展方向，强调通过设备适应性提升、控制精度强化与材料性能突破等方法，为深部资源开发提供全要素技术支撑，不断提高非煤地下矿山开采的安全性与高效性。

Abstract:
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.
