Abstract
To maintain the straightness of an unmanned longwall mining face, a track geometry surveying
model of the scraper conveyor was constructed based on the position of the shearer. A surveying instrument
was developed employing an inertial measurement unit and axial encoder. Surveying tests were conducted
using a longwall mining face mock-up, and the 3-D accuracy of the surveying instrument based on the
mean radial spherical error and the spherical error probable (SEP) radius was determined to be 20.78 mm
and 16.57 mm, respectively. The accuracy of the surveying system satis ed the requirements of a longwall
mining face.
