摘　　要：以回坡底煤矿11-1021巷底鼓现象为研究背景,通过弹性半平面无限理论分析得到9.88 MPa的巷道主应力差加剧了底鼓现象。基于此,对复杂应力叠加影响区含亲水岩层巷道底鼓控制进行了研究。底板充填加固方案的应用成功缓解了底鼓变形严重的问题,为安全生产提供了重要保障。With the floor heave phenomenon in 11-1021 roadway of Huipodi Coal Mine as the research background,the elastic semi-plane infinite theory analysis shows that the main stress difference of the roadway of 9.88 MPa aggravates the floor heave phenomenon.Based on this,the paper studied the floor heave control of roadway containing hydrophilic rock in complex stress superimposed influence zone.The application of floor heave reinforcement scheme successfully alleviated the serious floor heave deformation,providing an important guarantee for safe production.
