通过理论分析，用双纽线拟合煤体与采空区交界处下方底板岩层内支承压力分布，分析巷道受采动影响的程度。
Based on the theoretical analysies, lemniscate is used to fit the distribution of sustaining pressure in floor strata under the crossway of coal body and goaf. The degree of mining influence on roadways is studied, which serves as the scientific foundation of the design and the support of roadways.
