摘要
Abstract
In response to meet the application demands of high-mechanization technology for flexible formwork gob-side entry retaining,engineering technology optimization and practical research are carried out to improve roadway support effects and ensure safe and efficient advancement of the working face.Taking the gob-side entry retaining project at Shuangma No. 1 Mine as the background,systematic studies on roadway support structure optimization and mine pressure behavior characteristics were conducted.Technical upgrades were made to the flexible formwork construction process and supporting equipment,forming a complete set of surrounding rock control technology for flexible formwork gob-side entry retaining suitable for high-intensity mining conditions.Monitoring data show that after 150 m of gob-side entry retaining implementation,both the pressure variation of the flexible formwork wall and the deformation rate of the surrounding rock tend to stabilize.The maximum roof subsidence is 140 mm,and the convergence of the two sides is less than 30 mm.Under the synergistic effect of roadside support and in-roadway reinforced support,the deformation of the retained entry surrounding rock is effectively controlled,and the stability of the surrounding rock is significantly improved.关键词
