以屯兰煤矿18207工作面的胶带巷为研究对象,分析了二次采动影响期间该沿空留巷巷道表面位移量以及巷旁充填体的承载与变形规律。研究结果表明:二次采动影响期间沿空留巷顶底板、两帮及充填体是稳定的。
Taking the tape lane of 18207 working face in Tunlan Coal Mine as the research object, the surface displacement of the gob-side entry lane and the load-carrying and deformation rules of the roadside filling body during secondary mining are analyzed. The results show that the roof and floor of Gob - side entry retaining during the secondary mining process are stable.
