边角网在煤矿井筒十字中线恢复中的实践与分析

The Experiment and Analysis of Triangulateration Network for Restoration of Cross Line through Shaft Center

首先介绍了边角网在煤矿地面控制系统恢复中的应用,再利用恢复后的控制成果对井筒十字中线基点精确放样,然后再次利用边角网对放样的基点进行检测。以吴桂桥煤矿为例,阐述边角网在煤矿井筒十字中线恢复中的应用。

This paper firstly introduced the application of triangulateration network for restoration of ground control system in coal mine.Then it implemented the accurately setting-out of cross line through shaft center using the restored control results.Furthermore,it testified the base points by the method of triangulateration network.Taking Wuguiqiao coal mine as an example,it discussed the application of triangulateration network for restoration of cross line through shaft center.
