根据巷道帮部围岩水平位移量选择合理的锚索支护参数

Choice of Reasonable Anchor Cable Support Parameters according to the Horizontal Displacement of Surrounding Rocks

在煤岩巷道中,支护参数选择不合理容易使围岩发生严重的变形破坏。通过FLAC3D软件在硬岩中对不同锚索长度、不同锚索预紧力和不同锚索间排距的支护参数进行模拟,利用Tecplot软件来进行切片数据的获取,并输入到Origin软件中绘制出不同支护参数下以距巷道中心距离为X轴,以围岩水平位移量为Y轴的变化关系曲线图。

In coal and rock roadways,the unreasonable selection of support parameters can easily cause serious deformation and destruction of surrounding rocks.In this paper,the FLAC3D software is used to simulate the support parameters of different anchor cable lengths,different anchor cable pre-tightening forces,and different anchor cable spacings in hard rock.The Tecplot software is used to obtain slice data,and they are input into the Origin software to draw the relationship curve with the distance from the center of the roadway as the X axis and the horizontal displacement of the surrounding rock as the Y axis under different support parameters.
