Algorithmization of automatic control of pillar stability
There are two possible approaches to automatic control of pillar stability: parameteric and nonparametric.
Parametric control for a constant load on a pillar can be implementing by the method of one selected point (placing one sensor at the pillar center), and, for a nonstationary load, the method of two selected points (with two sensors placed in the horizontal cross-section of the pillar: one at the center and the other at 0.7R from it).
The best control quality obtained is with the nonparametric approach, although it requires multichannel monitoring.
The algorithms can easily be implemented by software or hardware means (eigher specialized or meeting the GSP or CAMAC standards).
