简介
In an environment, one of the natural geological hazards is land surface subsidence. Underground mining and subsurface coal fires are primarily responsible for subsidence of land. Activities, such as, over-exploitation of coal, minerals, groundwater and petroleum resources, depillaring of the existing galleries and water logging of the relinquished galleries are the major factors resulting in subsidence. The deformation is primarily measured in terms of change in ground elevation values (Z-dimension) at different time intervals at identified ground locations. All the conventional and exiting techniques have certain limitations in monitoring and predicting land surface subsidence. In this work, we predict the land subsidence in Jharia Coalfield, Dhanbad, India for one year in the interval of twelve days on the datasets collected through a monitoring technique called Modified PSInSAR. The sample datasets contains 14 …
