摘要
贯通测量是地下开采矿山井巷施工的重要环节。通过宏达矿业公司在天井贯通测量中应用手持激光测距仪配合半圆、挂罗盘测角的施测实践及分析,提出了消弱磁干扰和减小垂曲误差影响的实用方法,一方面提高了测量精度,另一方面也提高了测量人员在天井测量过程中的安全性。
Transfixion project measurement is a key part of underground mine tunnel construction. The measuring practice of cut raise transfixion with hand-hold laser distance finder, hanging compass and semicircle in Hongda Mining Industry Co. , Ltd. is analyzed. The methods to weaken magnetic interference and vertical curved error influence are put forward, which can enhance the measuring accuracy on one hand and ensure the measuring staff safety on the other hand.
