超长工作面高精度贯通技术的探讨

Probe into the High-precision Through Technology on the Ultra Long-distance Face

文中介绍了现代化高效矿井超长工作面的贯通误差预计及精度评定,通过实施高精度贯通的施测方法,发挥了仪器的极限精度,实现了巷道的高精度贯通。

In the paper, the estimation of through errors and precision assessment on the ultra long-distance face in a highly-effective modern mine is described. Due to use of the high-precision through survey method, the limit precision of the instrument is developed, realizing the high-precision through of the roadway.
