摘　　要：针对某煤矿3302轨道顺槽通过深基点位移测量,测得其巷道围岩深部位移。得出其受到上一工作面的采动影响,在不同深部的各基点位移量不同,并且对于不同部位的深部围岩来说,变形速度与变形量具有基本相同的规律。同时,围岩深部塑性区受力较为严重。依据此结果可以对巷道支护方案进行合理修正。By measuring the deep base point displacement of 3302 track crossheading of a coal mine,the displacement of deep surrounding rock of the roadway is measured.It is concluded that the displacement of the basement at different depths is affected by the mining of the previous face,and the deformation velocity and deformation are basically the same for the deep surrounding rock in different parts.At the same time,the surrounding rock deep plastic area is more serious stress.Based on this result,the roadway support plan can be properly amended.
