大坡度斜井联系测量的方法

Connection surveying method for large inclined shaft

本文提出适用于大坡度斜井联系测量的方法,并对坐标、坐标方位角、高程传递精度的影响因素遵循显著影响和忽略不计原则进行了分析,建立了具体的数学模型,提出了保证斜井联系测量精度的有效措施。理论分析和实践证明,该斜井联系测量的方法具有操作方便、精度高、占用井筒时间短、受外界环境影响小等优点。

In this paper,the connection surveying method for large inclined shaft was introduced,then according to the principles of remarkable influence and negligible influence,the influence factors for coordinate error,azimuth angle error,elevation error were analyzed,the concrete mathematical models were found,the effective measures for guarantee the precision were proposed.Theory analysis and practice proved that the connection surveying method had many advantages such as easy operation,high precision,occupied shaft shorter,and little affected by environment.
