Groundwater is of paramount importance for an agriculture-based country like India. Being a leading asset, the use of groundwater, primarily for irrigation and for various development activities over the years has adversely affected the groundwater regime in many parts of the country. With 2.4 percent of the total land area and 4.0 percent of the total available water, India has to serve 17.5 percent of the world population and 30 percent of livestock. In the year 2010, annual water demand was 813 BCM and it is likely to be 1093 BCM by the year 2025 and 1447 BCM by the year 2050. Thus, the available utilizable water resource of the country is considered insufficient to meet all future needs.

The mining sector is gradually growing the quality of human life. But, while permitting mining, the disturbance to the hydrological regime should be minimal or as less as possible. This study determines the interrelation of the mining process with water in general and groundwater in particular. To understand the groundwater-related problems of the mine, the hydrological and geological setup of the area is first studied. Concerning any mine or the mining area, hydrogeological setup encompasses aquifer characteristics, that is, nature, type, parameters, etc.; all local and regional geological details; plans for mining and total picture of hydrology, drainage, discharge, etc. The approach for scientific investigation, to search for solutions, usually includes field monitoring (pre-monsoon and post-monsoon monitoring), instrumental survey, groundwater modeling, and mine planning, that is, drainage, dewatering, etc.

Surface mining and underground mining are two major methods of mining for the exploitation of minerals from the earth.  The role of groundwater is very important in both methods because mining has an influence on hydrology.
