摘　　要：把顶板视为上覆岩层为条形区域的梁,对于有三个大矿柱支撑顶板的情况,用"简支梁"力学模型对其进行计算;而对于有一系列点柱支撑的顶板用"连续梁"力学模型对其进行计算。对两者计算结果进行比较,发现后者顶板的稳定性远好于前者。Regarded the roof as a beam that the overburden as a bar area,using ＇supporting girder＇ mechanical module for the roof supported by three big pillars to calculate.Using ＇consecutive girder＇ mechanical module for the roof supported by a series of points column to calculate.Comparing the calculation results,found that the stability of the roof that the latter is better than the former.

关 键 词：顶板 矿柱 力学模型 计算
