中文摘要：

运煤隧道经过采空区受到剩余变形而产生附加应力的影响，而附加应力的大小又与剩余变形的量值有关.通过理论分析与计算，得出了采空区产生的剩余变形量，并把剩余变形量按边界条件加载到三维数值模型上，按照隧道稳定验算的弹性梁理论，计算隧道的稳定性;得出了在剩余变形作用下，运煤隧道经过采空区稳定的结论.

英文摘要：

Since there exists a long-time residual deformation in a mined-out area,the coal tunnel through a coal goaf will be affected by the residual deformation,causing additional stress.The size of the additional stress is associated with the residual deformation.Through theoretical analysis and calculation,the residual deformation surrounding a coal tunnel is numerically evaluated.According to the residual displacement boundary conditions,the residual deformation is laid on a three-dimensional numerical model.According to the elastic beam theory,the stability of the coal tunnel is computed.We draw the following conclusions that the coal tunnel is stable under the effect of residual deformations.
