摘　　要：通过对沁新煤矿2207轨道顺槽采取相应的监测方法与监测仪器,测得其巷道围岩位移量。得出其受2205工作面采动影响,围岩内部出现变形位移,并且对于不同深度与部位的围岩来说,变形速度与变形量有其自身的规律。同时,随着围岩深度加大,变形位移量增加,之后逐渐趋于平缓。依据此结果可以对巷道支护方案进行合理修正。By adopting the corresponding monitoring methods and monitoring instruments for 2207 track crossheading of Qinxin coal mine,the displacement of surrounding rock of the roadway was measured.It is concluded that the deformation and displacement of the surrounding rock are affected by the mining of 2205 face,and the deformation velocity and deformation have their own laws for the surrounding rock with different depths and locations.At the same time,as the surrounding rock depth increases,the amount of deformation and displacement increases,and then gradually tends to be gentle.Based on this result,the roadway support plan can be properly amended.
