摘要
针对井下观测条件恶劣、风大等特点,尝试采用煤炭科学研究总院唐山分院开发的SET—5F防爆全站仪及四站法测量方法,有效提高了井下基本控制导线的测量精度和速度。
Aimed at adverse surveying condition of underground,SET—5F breakaway explosion all station instrument,which made in Tangshan branch of china coal research institute,and four station instrument are used surverying precision and speed of base control line are improved.
