Technical field
The utility model belongs to geologic prospect or mining industry technical field, in particular to a kind of geologic compass, the ground
Matter compass be mainly used for field landform make a preliminary survey, angle slope measuring or measuring core occurrence etc..
Background technique
Geologic compass, abbreviation circumferentor are common master tools in geologic prospect or mining operations, are mainly used for
Field landform makes a preliminary survey, angle slope measuring and measuring core occurrence etc..In addition to measure orientation, the measurement attitude of rocks is also field
The most basic working method of matter work, elements of attitude includes the trend, tendency and inclination angle of rock stratum.When measurement, general
Tendency and inclination angle need to be measured, and moves towards to add deduct by the numerical value of tendency 90 ° to obtain, when measurement tendency is with inclination angle, it is necessary to first
Tendency is surveyed, then measures inclination angle in tendency direction, so that some need the measurement of inclination data just to become cumbersome, and survey
Measuring inclination angle after amount trend or tendency again will cause greatly artificial or environmental factor error, so that when measurement inclination angle, compass
The crest line relied on is no longer horizontal.
Existing compass is often corrected according to the observation when correcting magnetic declination, lacks quantitative control, in this way
It is easy for the phenomenon that causing the value of correction to deviate normal correction value.When carrying out angle measurement, existing compass is mostly to use
