Mine Planning & Economics Subsidence and Surveying

Section: 2 Mine Subsidence and Surveying


Subsidence investigations, prediction, control measures and surveying


Important Achievements of the Section: 

(a) Developed expertise in subsidence measurement due to extraction of coal and gas over small and large areas using Total Station and Global Navigation satellite system (GNSS).

(b) Developed the concept of Non-Effective Width (NEW) for Indian coalfields.

(c) Developed three-dimensional subsidence prediction model for single seam and multi-seam for Indian geo- mining conditions using modified Influence Function method for the safety of surface structures, agricultural land and forest land.


(d) Development of causes, mechanism and remedial measures of pot-hole subsidence.

(e) Expertise in surveying of opencast mines for volumetric computation of earthwork excavation, dump and stockpile survey using Total Station and 3D Laser Scanner (LiDAR).


(f) Establishment of Base Station, Primary control points and secondary control points using Global Navigation Satellite System (GNSS).


(f) Demarcation of mine block boundary and topographical survey using GNSS.


(g) Geophysical investigation using Resistivity Imaging Technique over mining area and groundwater exploration
