1. The purpose of the instrument

DQL100-G1 type mine suspension compass and slope gauge form a set,

which is used as an auxiliary measuring instrument for mines. The instrument is mainly used

 

Measure the magnetic azimuth angle of the secondary roadway in the mining

area and the mining face and the inclination angle of the compass wire edge.

 

2. How to use

The use of the instrument is supported and guided by the measuring rope, and is

centered and leveled by visual inspection and read.  After tightening the measuring rope,

first use a grade gauge to level it or measure the inclination angle, and then hang the compass

to measure the magnetic declination. For the convenience of reading, the zero end of the dial

is aligned to the front when the compass is suspended. If the slope on the measuring track

is relatively large, which will hinder the level of the measuring rope, the step method shall

be used to measure the time in sections and try to make each section of the measuring r

ope parallel in the horizontal plane.
