摘 要:以1503采面切眼掘进及围岩控制为背景,对切眼掘进以及围岩支护技术进行研究,具体将大断面切眼分两次掘进,以便降低切眼掘进难度;综合采用锚网索、架棚方式控制大断面切眼围岩变形。依据现场情况对切眼掘进及围岩控制方案进行设计,经现场应用后,切眼顶底板、两帮变形量分别控制在113 mm、91 mm,围岩控制效果较好。With the background of 1503 mining face cuttings and control of surrounding rock, the study of cuttings and surrounding rock support technology was carried out, specifically splitting the large section cuttings into two cuttings in order to reduce the difficulty of cuttings;the integrated use of anchor network cable and scaffolding method to control the deformation of surrounding rock of large section cuttings. The design of the cuttings and the surrounding rock control scheme was based on the site conditions. After the application on site,the deformation of the top and bottom plates of the cuttings and the two helpers were controlled at 113 mm and 91 mm respectively, and the surrounding rock control effect was good.
