摘　　要：根据煤层底板的地质特征,建立完整水平层状底板地质模型,利用数值模拟计算在相同的地质和采矿条件下不同结构底板的采动效应特征(应力重新分布和底板破坏深度),为底板突水评价提供科学依据。A geologic model of intact and horizontally-bedded coal seam floor was built up according to the geologic characters of the seam floor. The mining effect was presented under the same geologic and mining conditions by numerical simulation 'stress redistribution and the destructive depth of seam floor', this thus provides the scientific basis for evaluating water inrush from seam floor in coal mine.

关 键 词：煤层底板 岩体结构 采动效应 数值模拟
