联系测量在某矿山的应用

Application of Connection Survey in a Mine

某矿山330第一运输平硐自2005年投入使用后已有20年的历史,巷道顶板的控制点已基本废弃或丢失,无法满足巷道中各溜井的生产改造工程的工作需要。当进行实地测量作业时,由330第一运输平硐口引入控制点,水平距离可达2~3km,实测过程工作量大,也易导致精度无法满足设计需求的情况。2022年8月,根据矿山生产建设需要,通过一井定向作业的方式,重新将地表坐标系统导入330m第一运输平硐,为后续的生产作业提供了方便。

The 330 first transportation adit of a certain mine has a history of 20 years since it was put into use in 2005.The control points of the roadway roof have been basically abandoned or lost,which cannot meet the work needs of the production and transformation projects of each chute in the roadway.When conducting on-site measurement operations,control points are introduced from the 330 first transportation adit,with a horizontal distance of up to 2~3 kilometers.The workload of the measurement process is large,which can also lead to situations where the accuracy cannot meet the design requirements.In August 2022,according to the needs of mining production and construction,the surface coordinate system was reintroduced into the 330 m first transportation adit through directional operation of one well,providing convenience for subsequent production operations.
