在分析研究下向进路结构和受力特征的基础上，提出下向进路开采进路结构受力模型是“两侧弹性基础之上的板结构力学模型”．采用数学力学解析法，推导出假顶在垂直载荷作用下的下沉曲线方程，为下向进路充填采矿假顶结构参数设计的实践提供了一些理论依据和参考．
Based on the analysis of the approach structure and the force characteristics, this paper puts forward that the downward force approach is the “mechanics model of plate structure on the basis of elasticity on both sides”. Mathematical mechanics analysis method is used to deduce the subsidence curve equation of false roof under the action of vertical load, which provides some theoretical references and reference for the practice of parameter design of downfill mining roof structure.
