| 摘 要： | 徐州矿区夹河煤矿-1010 m采区开掘以后,矿山压力显现剧烈,巷道底鼓、两帮位移较大,影响巷道正常使用。通过锚网梁索及喷浆加固围岩技术,改变了围岩的力学性质,对失修巷道取得了良好的支护效果,对类似的巷道控制巷道变形及后期维护有一定的借鉴作用。

| Abstract: | -1010 m mining area of Jiahe coal mine of XuZhou mining area after cutting,mine pressure ap-pear,two displacement of floor heave of roadway is bigger,which affects the normal use of roadway. By beam metal net and shotcrete reinforcement technology of surrounding rock,the mechanical properties of surrounding rock is changed,which gets good supporting effecf for the disrepair roadway,and is of certain reference value to the roadway deformation control and later maintenance. |
