Gidi is an old colliery that started functioning in 1958. Several seams (Argada, Argada-A, Argada-B, Sirka, Bansgarha, Hatidhari and upper & lower Semana) have been worked by underground mining methods, either through independent mine entries / inclines or drifts from one seam to another. In addition, the mine has been worked by opencast methods in six patches (Quarries 1, 2, 3, 4, 5 and 6). Except Qaurries 2 and 3, all the other quarries are filled up water to a maximum water level of . Giddi-A open cast project is located in the east central part of South Karanpura Coalfield. All the underground workings of Giddi-A colliery were stopped since March 1984. Presently the mine operation is limited to opencast working in Quarry no. 3.
