巷道曲线段施工控制方法探讨

Discussion on Construction Control Methods in the Curve of Roadway

就巷道曲线段施工的几种控制方法作一对比。施工前,测量部门根据巷道曲线参数按圆曲线中心切线两次给线或等分曲线按弦线几次转向给线的计算方法大同小异,故就切线给线进行论述。

The paper compares several kinds of constructing methods in the curve of roadway, and deales with the methods of laying lines by tangent line.
