摘要：为研究倾斜煤层底板破坏深度影响因素(采深、采高、工作面斜长、煤层倾角、以及顶、底板岩性组合)对底板采动破坏深度的敏感性。以阳城煤矿的采场条件为工程背景,基于FLAC3D数值模拟软件对1309工作面底板采动破坏深度进行正交模拟,并运用方差分析法对模拟结果进行分析研究。研究表明:各主控因素对底板破坏深度的敏感性主次顺序为:顶板岩性组合>工作面斜长>底板岩性组合>采深>采高>煤层倾角。其中,顶板岩性组合和工作面斜长高度显著,底板岩性组合、采深及采高显著,煤层倾角不显著。
In order to study the sensibility of inclined coal seam floor failure depth factors, such as mining depth, mining height, working face length, coal seam dip angle and roof and floor lithological combination, to the depth of coal seam floor damage. Tak- ing the stope conditions of Yangcheng Coal Mine as project background, the orthogonal simulation which is based on FLAC3E） nu- merical simulation software is made to the depth of coal seam floor damage at 1309 working face. Furthermore, this paper analyzes and researches the simulated result in the way of variance components method. Research shows that the order of each factor that influences floor damage depth is as follows： roof lithological combination, working face width, floor lithological combination, mining depth, mining height and coal seam dip angle. Roof lithological combination is the highly significant factor, and the significant factors include floor lithological combination, mining depth and mining height, while the unapparent factor is coal seam dip angle.
