摘　　要：为提高煤矿巷道贯通精度,确保巷道顺利贯通,以某巷道贯通工程概况为例,预计贯通误差,分析贯通测量结果,通过应用仪器测量、优化观测手段、改进数据处理方法等操作,使巷道贯通测量的精准度得到提高,保障了该巷道精准贯通。研究表明,该14 km贯通工程精度水平在重要方向的贯通误差控制在0.128 m,高程贯通误差控制在0.215 m,实现了精准顺利贯通,可为类似工况下的巷道贯通提供参考。In order to improve the accuracy of coal mine tunnel penetration and ensure the smooth penetration of the tunnel,taking the overview of a certain tunnel penetration project as an example,the expected penetration error,analysis of penetration measurement results,application of instrument measurement,optimization of observation methods,improvement of data processing methods,and other operations,the accuracy of tunnel penetration measurement has been improved,ensuring the accurate penetration of the tunnel.Research has shown that the accuracy level of the 14 km connection project is controlled at 0.128 m in important directions,and the elevation connection error is controlled at 0215 meters,achieving precise and smooth penetration,which can provide reference for tunnel penetration under similar working conditions.
