| 摘 要： | 针对急倾斜煤层巷道支护现状，提出采用锚网索支护新技术对试验巷道进行支护改革．通过对试验巷道表面位移、围岩深部位移和锚杆（索）受力的现场监测，分析了试验巷道矿压显现活动规律，掌握了试验巷道在锚网索支护下的围岩变形规律，得出了在急倾斜煤层巷道采用锚网索支护是可行的．这为锚网索支护在急倾斜煤层巷道的推广应用和支护参数设计提供了科学依据，对改善急倾斜煤层巷道的维护有着积极的意义．

| Abstract: | According to the current situation of supporting steep seam roadway,a new bolt-mesh-anchor support technology was put forward.Through monitoring the surface displacement of roadway,the deep displacement of surrounding rock,and the stressed situation of bolt(cable),the ground pressure rule of the trial entry was analyzed,and the deformation regularity of the surrounding rock obtained.The results show that the bolt-mesh-anchor support technique is suitable for the steep seam roadway.This technology has provided a basis for determining supporting parameters and so can be used for supporting the steep seam roadway,which is significant for the maintenance of steep seam roadway. |
