摘要
介绍了一种测算巷道顶板真倾向、真倾角的快捷方法 ,分析了优缺点和适用条件。在已知巷道掘进方位角前提下 ,仅现场实测两个伪倾角数值 ,经简单公式计算 ,便可得到顶板产状。
This paper recommend a royal road about dip angle and tendency of the tunnel roof and analysed the applicability.On condition that we have known the true azimuth of the tunnel and determined only two false dip in the tunnel ,the attitude value has gotten by simple computation.
