然而，很少见到考虑下煤层采动影响的力学模型。下伏工作面推进过程中，原本

However, there are few mechanical models that consider the impact of mining in the lower coal seam. During the advancement process of the underlying working face, the original clear law of the evolution of the stress field of the floor rock mass is not clear, which limits our ability to evaluate the reasonable location of the roadway

However, it is rare to see a mathematical model that considers the effects of coal seam extraction. In the process of lowering the work surface propulsion, the original clear law of the stress field of the subslab rock body is not clear, which limits our ability to evaluate the reasonable position of the roadway

However, there are few mechanical models considering the influence of coal mining. In the process of advancing the underlying working face, the evolution law of stress field of floor rock mass is not clear, which limits our ability to evaluate the reasonable position of roadway<br>
