| Abstract: | 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. |
