Abstract
In the process of coal resource mining,the excavation of"three soft"coal seams along the goaf faces a prominent contradic-tion between safety and resource recovery.The problems of easy deformation of surrounding rocks,instability of coal pillars,and high risk of water damage urgently need to be solved.To address these challenges,theoretical analysis and on-site measurement methods were comprehensively applied to determine that a coal pillar width of 6 meters is a reasonable choice.At the same time,a joint support-ing scheme of anchor rods and cables was proposed for surrounding rock control,and effective water exploration and drainage technical measures were developed.The research results not only improve the resource recovery rate and reduce the supporting cost,but also sig-nificantly enhance the safety and stability of roadway,providing a scientific and practical solution for gob-side entry driving of"three soft"coal seams.关键词
