摘要/Abstract

摘要： 通过对Ⅱ28采区运输上山的顶板离层、表面位移、深部位移以及锚杆锚索受力状态实测分析，得出底板跨采条件下锚网索支护巷道的围岩变形规律；结果表明，围岩变形主要发生在上方跨采工作面采动影响剧烈阶段，尤其是对于裂隙比较发育的岩体，合理的支护可控制围岩的变形量，保证巷道的断面满足生产要求。

Abstract: Through the analysis of measured data on roof abscission layer, surface displacement, deep displacement and forced state of bolt and cable of Ⅱ28 mining area up roadway, surrounding rock deformation law of cable anchor support roadway under condition of floor cross mining was obtained. The result indicated deformation of surrounding rock mainly occurred at effect violent period of mining of above cross mining working face,especially at the rock mass with more developed fracture. Reasonable support could control the deformation of surrounding rock and ensure the section of roadway could meet the request of production.
