Abstract: The prominent contradiction between high stress and low strength in deep soft surrounding rocks of coal mines easily induces large deformation disasters in roadways, seriously threatening safe production. Borehole pressure relief technology enhances the strength-to-stress ratio of surrounding rock through stress release and space compensation mechanisms, achieving significant progress in both theory and engineering practice in recent years. This paper systematically reviews domestic and international research trends in borehole pressure relief technology, focusing on aspects such as the mechanism of action, parameter design, model testing, and effectiveness evaluation. The key conclusions are as follows: (1) Pressure relief boreholes achieve triaxial stress coordination and shear dilation compensation by inducing crack propagation, forming a stress distribution pattern characterized by shallow pressure relief and deep stress bearing, and synergize with high-strength support to form a "relief-support synergy" system; (2) Key parameters such as borehole diameter, spacing, and depth significantly influence the pressure relief effect. While preliminary multi-factor coupled design guidelines have been established, their applicability under complex geological conditions requires further verification; (3) Current technology still faces bottlenecks, including an incomplete quantitative evaluation system for pressure relief effects, unclear energy evolution mechanisms, and a lack of dynamic coupling theory for pressure relief and support. Looking ahead, future efforts should prioritize establishing a "multi-field coupling and dynamic-static synergy" analytical framework for pressure relief mechanisms, and developing dynamic constitutive theories that incorporate thermal-hydraulic-mechanical-damage (THMD) effects. It is essential to research and develop precise pressure relief equipment based on while-drilling perception and intelligent decision-making systems, while also optimizing differentiated support and grouting reinforcement methodologies. The goal is to construct an integrated control system of pressure relief - support - reinforcement, thereby advancing borehole pressure relief technology toward intelligent, precise, and large-scale development.
