| Abstract: | A newly type instrument, Optical Spotting hole Instrument,GBY -I , will be described here.This instrument will enable various pattern of tunnel blast to amplified and to be projected on the driving working face.Once the position of holes on the whole section can be quickly and accurately shown by the very light dots.It has been pr-oved that this instrument spots the holes quickly and accurately and has highly economic benefit in its practical use. |
