The Raniganj coalfield of West Bengal, India, has been producing non-coking coal of exceptional quality for 246 years, making it the oldest coal mine in India. In this coal mining region, the "room and pillar" mining method is employed to dig coal, resulting in local subsidence that comprises a number of huge subsidence ponds and minor area collapses. Subsidence significantly impacts the environment, resulting in a cataclysmic disaster that destroys public infrastructure and even causes death. The majority of land subsidence is produced by forces that apply pressure on the surface, such as groundwater extraction, mining, excessive development, and similar reasons. A very precise Differential Global Positioning System (DGPS), which is an enhanced GNSS, is used to monitor the movement of the ground. There are nine rover stations and three base stations, which are reoccupied at an interval of months and installed for hours. Since 2019, the DGPS has been used for this purpose....
