Dhanbad is second largest and the most populous city in the east Indian state of Jharkhand. It is popularly known by the name ?The Coal Capital of India?. Looking into the etymology, the name Dhanbad is believed to have been derived from the words "Dhan" which means wealth and Abad which means prosperity. When the words are put together, it means "prospered with wealth" for being a mineral-rich region. Another alternate explanation attributes the name of the city to its rich paddy fields as "Dhaan" in the local language means paddy. Both of these explanations make equal sense because the city is indeed quite rich in minerals and it also has the largest rice producing farms in Jharkhand. The chief economic source of the city is mining and some of the largest mining production units are situated in Dhanbad. Companies like Tata Steel, Eastern Coalfields Limited (ECL), Bharat Coking Coal Limited (BCCL), and Indian Iron And Steel Company operate in Dhanbad. Dhanbad Rail Division generates a lot of revenue and ranks second after the Mumbai division. Dhanbad has many reputed educational institutions such as the Indian School of Mines, IIT Dhanbad, Patliputra Medical College and Hospital, Central Institute of Mining and Fuel Research, etc. Places like Maithan Dam, Panchet Dam, Bhatinda Falls, Shakti Mandir and Topchanchi Wildlife Sanctuary serve as major tourist hubs in this city.
