为有效控制跨采巷道附加变形，保证矿井正常生产提供了依据。
The results provide a basis for controlling additional roadway deformation efficiently and ensure the regular production of the mine.
以某矿3225大巷为例，总结了巷道围岩变形规律，提出了跨采底板巷道维修方法，考察了维修效果，具有一定借鉴意义。
In 3225a mine roadway as an example, summed up the roadway deformation law, proposed an inter-mining floor roadway maintenance methods, inspected the maintenance effect to a certain extent learn.
留设保护煤柱时，底板岩巷应位于集中应力区的外侧或跨采时工作面应推过足够距离，使巷道靠近采空区应力恢复区的下方。
The floor roadway should be located out of the abutment stress zone when protection coal pillar is retained, or the working face should be pushed away for enough distance under overhead mining.
