The following terms and definitions as defined in GB/T 7665-2005 and GB/T 16414-2008 apply to this document.
3.1
Mining stress-induced stress
The mining project affects the stress in the rock mass.
[GB/T 16414-2008, definition 2.27]
3.2
Stress sensor stresstransducer
A sensor capable of measuring the stress of coal rock, usually composed of a stress sensitive component and a conversion component.
3.3
Monitoring point stress-monitoringpoint
The location where the sensitive components of the stress sensor are buried in the coal and rock mass.
3.4
Monitoring point depth stress-monitoringpointdepth
The vertical distance between the buried position of the sensitive component of the stress sensor and the surface of the alley.
3.5
Monitoring group stress-monitoringpointset
A collection of several monitoring points that are close in distance.
3.6
Stress change rate
The amount of change in stress at the monitoring point per unit time.
4 mining stress monitoring program
4.1 Main functions and technical parameters of mining stress monitoring system
4.1.1 The stress of coal and rock can be monitored online, and the stress data is automatically uploaded to the ground server and stored in time series.
