摘　　要：针对巷道弯道造成的测量困难、巷道成型效果差等问题,巷道直线段的测量采用中线延伸方法,巷道曲线段的测量采用中线标定方法,要求曲线段中线标定误差与设计方位的误差小于±1’。现场实际测量结果表明:对曲线段巷道采用中线标定方法的效果较好,保证了巷道掘进的直线度,巷道成型效果良好。In view of the difficulties in measurement caused by the bend of the roadway and the poor forming effect of the roadway,the middle line extension method is adopted in the measurement of the straight line section of the roadway,and the middle line calibration method is used in the measurement of the curve section.It is required that the error between the calibration error of the center line of the curve section and the design orientation is less than±1 inch.The field measurement results show that the middle line calibration method for curved roadway has good effect,ensures the straightness of roadway excavation,and the roadway forming effect is good.
