About Dhanbad District :
Dhanbad district was constituted in 1956 by carving out the old Dhanbad subdivision, Chas and Chandankiyari police stations of the Sadar subdivision of the erstwhile Manbhum district. Dhanbad is Police district since 1928. The re-organisation of the districts in the State of Bihar which took place after 1971 did not affect the district of Dhanbad. In 1991 a part of Dhanbad district was sliced away to form Bokaro district. The district is bounded on the west by Giridih and Bokaro on the north by Giridih and Dumka and on the east and south by Purulia district of West Bengal. The total geographical area of the district is 2886 Sq. Km. The distrcit has one sub-division called the Dhanbad Sadar and 8 blocks viz. Jharia , Baghmara, Dhanbad, Nirsa, Govindpur, Baliapur, Tundi, and Topchanchi. The blocks in turn have 181 panchayats and 1348 villages. The important places to visit in the district are Charak Pathar, Chati Gobindpur, Gopalpur, Jhinjhipahari, Meva, Panrra, Chark – Khurd, Topchanchi, Maithon, Panchet and Jamadoba.
