3 Overview

The geological compass is a compact geological and mining measuring instrument with compact structure, small size and easy to carry: It is an indispensable measuring tool for measuring azimuth angle and ground slope (inclination) in field geological work: With the help of it, you can quickly Measure (preliminary and fast rough measurement method) the azimuth angle from the instrument's positioning point to the target, and roughly measure the pitch of the target plane horn: It can measure various structural elements of igneous rocks, such as rock layer, fold axis, fault plane, joint plane and other structures: The spatial position of the surface, the occurrence of the ore body, etc: It can also be used for ground wind direction measurement at civil aviation airports and direction determination for outdoor sports: Installation and adjustment of solar equipment: Used for rough measurement of azimuth angle and inclination angle, also known as slope angle (y/x): surface unit The degree of steepness and gentleness is usually the ratio of the vertical height of the slope to the distance in the horizontal direction: The arctangent function of this ratio is the slope: Bevel angle α,tanα= Calibration of geological compasses for x purposes: The typical structure of the instrument is shown in Figure 1: ......
