Cleat mapping and integrated laboratory studies of selected coal samples from a corehole/ coal mines in Chalkari and Phusro areas of East Bokaro Coalfield were carried out to find coalbed methane prospectively of the area. A total of 35 coals seams with individual seam thickness in the range of 0.2- 16m were observed. The coals in general have low moisture content (0.6-2.8%) and moderate ash content (35.28-8.22%). With increasing depth dry, ash-free volatile matter (daf) has been found to decrease but there is no relationship between ash content and depth. The vitrinite reflectance (VRo) (0.85
