贯通测量技术在煤矿测绘中的应用

Application of through surveying technology in coal mine surveying and mapping

贯通测量是近年发展起来的一种的用于矿山测量的新技术,具有操作简单、测量精度高、耗时短的优点。对地理条件恶劣的西部矿山提出了基于贯通测量的新方案,该方案以最佳管通点求解理论为理论依据,计算确定了最佳贯通点K的位置,大大降低了使用GPS、全站仪后地面平面控制等的预计误差,解决了西部地区矿井国家控制点等级较低或可用点位较少的问题,为矿井的安全生产奠定了基础。

Through measurement is a new technology developed in recent years for mine measurement.It has the advantages of simple operation,high measurement accuracy and short time consuming.This paper proposes a new scheme based on through-through survey for western mines with bad geographical conditions.Based on the theory of optimal pipe-through point solution,the position of the optimal through-through point K is calculated and determined.The prediction error of ground plane control after using GPS,total station is greatly reduced.It solves the problem that the national control point grade of the mine in the western lower or the available point is less,which lays a foundation for mine safety production.
