双激光指向仪在巷道掘进中的应用分析

Application of Double Laser Directional Instrument in Roadway Excavation

针对巷道掘进过程中,巷道中线及坡度线采用水准仪、全站仪和经纬仪等设备测量无法保证测量精度的问题。基于此,介绍了双激光指向仪在巷道掘进中的应用,分析了激光基准的构建及激光转换次数的限制。其方向性好,较直观,便于施工,提升了工程质量,确保了煤矿安全生产。

In view of the problem that the measurement accuracy can not be guaranteed by using leveling,total station and theodolite in the middle line and slope line of roadway,this paper introduces the application of double laser direction meter in roadway heading.The construction of laser reference and the limitation of laser conversion times are analyzed,which is directional,intuitionistic,convenient for construction,improves the quality of the project and ensures the safety of coal mine production.
