Assessment of Water Condition in Underground Mine Workings of Belgaon Coal Mine, India
https://orcid.org/http://orcid.org/0000-0002-0570-7625
Belgaon underground coal mine is located in Warora tehsil of Chandrapur district, Maharashtra, India. ‘Mayo seam’ at Belgaon mine has a total thickness of 11 m but only the bottom section is found to be mineable, which has seam thickness varying from 3.2 to 3.7 m. This coal seam is dipping at 1 in 6.25 to 1 in 20 and is being developed along the floor by leaving a coal layer of 0.5–0.6 m against the shale roof. Panel D2-1 of the seam is developed at a depth of approximately 230 m by Bord and Pillar method with pillars of 40 m × 40 m in size. This D2-1 Panel has been planned for depillaring with caving to extract the coal and accordingly support design work as well as hydro-geological study, which has been carried out both for safety and also for statuary compliance. This research paper focuses on the site-specific hydrogeological study performed for water assessment in the Moturs/Barakar coal formations including related water management. The study is based on the encountered geological conditions, local aquifer parameters and other site-specific field observations. Both primary data and secondary data have been used for analysis and discussion in this study. The scientific evaluation carried out concluded that extraction of coal from the Depillaring panel D2-1 is safe and the creation of goaf, as a result of the depillaring operation, will cause an insignificant impact on the water-charged Kamptee series as a whole. Encountered geological features of the underground working areas will play an important role in the magnitude of water quantity.
