Abstract

This paper systematically reviews the evolutionary trajectory of coal mine gas drainage technology, with a focus on analyzing the principles, methodologies, and application status of key technologies, including gas drainage in high-permeability coal seams, pressure-relief gas drainage in adjacent seams, enhanced gas drainage in low-permeability coal seams, and comprehensive gas drainage approaches. Research indicates that with continuous technological advancements, the efficiency of gas drainage has significantly improved. However, challenges persist, such as the difficulty in extracting gas from low-permeability coal seams and the high precision requirements for drilling operations. Future development trends include the integration of intelligent drainage systems, novel permeability-enhancing technologies, the adoption of green mining concepts, and the collaborative optimization of multiple technologies. This study provides technical references and developmental insights for gas management and resource utilization in coal mines.
