Abstract

Karharbai formation (Permian) is the part of Giridih coalfield and most important on amongst the Hazaribagh group of coalfields of lower Gondwana supergroup. It contains some of the best coking coal of India. Giridih basin is the smaller basin contains karharbari and Barakar formations occupy about 18 km2 of the area. The ECR approached CMRI (nowCIMFR) for the detailed evaluation of ground study and development of the discreet ground stabilization design for laying railway tracks to run MBG (1987) train load along the proposed layout above the basin. The basin, being well-formed but very small in size, has certain typical uniqueness that is not generally found in the rest of Giridih basin. In addition, it is also affected by a few local faults. The dip of a coal seam significantly varies here in both, magnitude and direction, from place to place, and the seams plunge as well, Moreover, these seams frequently merge and/or split at many locations. As a result, precise comprehension of the genesis and pattern of formation of this site becomes very difficult. An attempt has been made in this paper to explain the coal seam patter and number of coal seam in Karharbari basin, Giridih. The is the part of the work approaches by ECR.
