Which one among the following is the first and the oldest Government-owned coal mining company in India ?

Singareni Collieries Company Limited (SCCL), incorporated in 1920 with its origins going back to 1889, is the oldest government-owned (jointly owned by the Government of Telangana and the Government of India) coal mining company in India. Eastern Coalfields Limited and Mahanadi Coalfields Limited are subsidiaries of Coal India Limited formed much later after nationalisation (1970s), and Neyveli Lignite Corporation deals primarily with lignite, not coal, and was set up in 1956. Hence SCCL is the first and oldest government-owned coal mining company.
