摘　　要：为使8203回风顺槽巷道形成系统,保证工程安全顺利进行,基于组合梁理论,进行了回风顺槽巷道的爆破施工技术以及支护方式研究,采用钻爆法、楔形掏槽法施工、锚杆支护,顶板、底板下沉最大变形值为121mm、114mm,回风巷道稳定性控制在安全范围内。In order to form a system of 8203 return air tunnel and ensure the safety and smooth progress of the project,based on the theory of composite beam,the blasting construction technology and support mode of the return air tunnel are studied.The drilling blasting method,wedge cutting method and bolt support are adopted.The maximum deformation value of the roof and floor subsidence is 121mm and 114mm,and the stability of the return air tunnel is controlled within the safe range.
