本文研究并揭示了跨采巷道围岩松动圈随采动影响的特征和变化规律，包括：（１）跨采巷道围岩松动圈的形状、过程、时间性特征，（２）跨采围岩松动圈增量及围岩碎胀变形增量的数学模型。并在此基础上提出了相应的支护对策。
This paper studies and reveals the characteristics and variation of the influence of the loose ring of mining surrounding rock along the mining roadway, including: (1) the shape, process and time characteristics of the loose ring around the roadway; (2) Mathematical Model of Increment of Loose Circle and Incremental Deformation of Surrounding Rock. And on this basis, the corresponding support measures are proposed.
