地下巷道围岩变形规律的实测研究

摘要

大型煤矿在开挖后,巷道的变形与稳定性变化成为煤矿安全性研究的基础.本文以河南永煤集团地下煤矿综放面布置的具体条件,进行现场实测,根据测量结果对综放回采巷道在围岩开挖过程和回采过程中的岩体表面和内部变形进行了综合研究,从而得出巷道围岩在开挖和回采期间的变形规律.研究结果对改善大型地下工程巷道的维护和煤矿安全生产有着积极的意义.%After the excavation of a large coal mine, the deformation and stability of roadways become very crucial basis in the study of mine safety. Based on the field data of Henan Yongmei Group, the surface and internal deformation of the adjacent beds during the process of excavation and extraction are analyzed in this paper, and the deformation law is obtained. The conclusion has great meanings in the roadway maintenance and safety production of the mine.
