井筒十字中心线标定的设计与实施

Design and practice of shaft cross centre line calibration

井筒十字中心线是矿井工业广场总平面设计的基础。介绍了井筒十字中心线标定原理,结合东刘家矿区工程实际,简述了井筒十字中心线标定方案及施测过程,并对实测精度和误差进行了评定分析。东刘家矿区井筒十字中心线标定,确保了矿井工业广场总平面设计及施工的顺利进行。

The cross centre line of shaft is the design basis of mine industrial square site planning.The paper introduces the calibration principle of shaft cross centre line.Combining with the measuring practice in Dongliujia mining area,the calibration scheme and measuring process of shaft cross centre line is introduced.Meanwhile,the measuring accuracy and error is analyzed.The calibration of the shaft cross centre line ensures the smooth proceeding of the mine industrial square site planning and construction.
