3 Terms, definitions and abbreviations
3.1 Terms and Definitions
The following terms and definitions apply to this document.
3.1.1
A general term for a series of interconnected observation points set up on the surface according to certain requirements and that can reflect the characteristics of movement and deformation.
3.1.2
observation frequency
When measuring an observation station, set the number of observations and time intervals as needed.
3.1.3
Connectivity measurement connectsurvey
The surveying work of measuring the control points and the mining area control network to determine the plane position and elevation of the control points is completed and connected.
3.1.4
The measurement work to determine the plane position and elevation of the surface movement observation station is carried out after continuous measurement, before the surface movement and after the surface stabilizes.
