With massive measured data of the river-crossing trigonometric leveling survey,the change rule of atmospheric refraction coefficient is calculated and analyzed in elevation transmission region of a bridge,and some beneficial conclusions are obtained.

Analysing the features of the advanced measurement instrument — the total station,the measurement principle of the trigonometric levelling and the error,the paper puts forward to use the total station trigonometric levelling in the mining area has advantages such as free from landform,small error,high precision,great efficiency,etc.
