新元公司集中胶运和辅助运输巷贯通误差预计 摘 要 新元公司集中辅助运输、集中胶带大巷贯通测量集中胶带运输大巷和集中辅助运输大巷贯通工程是新元公司实现早日投产最主要的前期工程,为了尽早实现贯通,集中胶带运输大巷和集中辅助运输大巷采取相向掘进的措施。贯通后,将相遇点两端的中线延长到K点位置,两条中线延线应在K点相接,若接不上,产生误差,用小盒尺精确量取其偏差值,即为该巷道在水平重要方向的实际偏差值,若用激光指向,则量取两条激光在K点处的偏差值。将相遇点两侧的腰线延长至K点,用小盒尺量出两腰线间的垂直距离,即为垂直方向的实际偏差值。在最后给线的两端的导线点置仪连测,将导线附合起来,最后求出实际贯通方位差和坐标差。同样,用水准测量,把两端的腰线连接起来,求出两端水准测量高程闭合差。贯通偏差在允许范围内,定期进行检查测量和填图，并按照测量结果及时调整中线和腰线。 关键词：贯通测量 误差预计 精度 SGD companies to concentrate plastic Win and auxiliary transport roadway is expected to link error Abstract SGD auxiliary transport companies to concentrate, concentrated belt roadway connecting survey concentrated tape transport roadway and centralized auxiliary transport roadway linking project is the company to achieve an early Xinyuan commissioning of the most important early works, for the early realization of traffic. centralized tape transport roadway and centralized auxiliary transport roadway driving directions taken measures. Link, will meet both points of the centerline extended to K location, the two middle line should be extended in K-phase point, if not receive, errors, and CH-foot accuracy is the lesser of deviation, that is the important level of roadway in the direction of deviation of the actual values Using the laser point, the volume for the two laser K point deviation. Will meet on both sides of the waist line extended to K, with a sufficiently good two CH-foot waist line between the vertical distance, namely, the vertical direction deviation of the actual value. In the final line to the ends of the wire point home even measuring instrument, the wire attached to them, and finally obtained the actual position of linking poor and coordinates worse. Similarly, the standard of measurement used, connecting the two ends of the waist line, the standard measurement obtained at both ends closure elevation difference. Linking deviation within the permissible range, regular inspections and measurements mapping, and measurement results in a timely manner in
