大采高工作面不同面长顶板冒落高度的分析研究

Large mining height under different working face length analysis of roof caving height

通过数值模拟,采高对冒落带的影响,压力拱理论的分析对不同工作面长度下顶板冒落情况进行分析比较,得出与现实较为相符的拟合曲线,为大采高合理确定工作面长度的确定了理论基础。

In this paper, through numerical simulation, the influence of mining height are broken on MaoLaDai, pressure arch theory analysis on different length of working face under the condition of roof caving are compared, and analysis it is concluded that a more consistent with reality fitted curve, to large mining height are broken reasonable face length determines the theoretical basis.
