Paper Abstract

Analytical and close-range photogrammetry is used for strata deformation and subsidence study over underground mining excavation with chief objective of quick analysis. This paper describes methodology and results of planar movement measurement of a large number of points fixed over physical model by analytical exploitation of the projective correspondence between the frontal plane of the model and plane of photographs, taken over different stages of workings. Taking the advantage of synoptic view of this technique, the monitoring of subsidence over active underground excavation was also done to cut short on-site measuring time and to avoid error due to additional movement during observation period. Five camera stations were designed in a row at 100 m distance from the row of measuring pillars to cover the panel of 270 m x 100 m dimension.
