About 999.36 m of GP logging was completed. Nine regional coal seams /zones and few local coal seams ranging in thickness from less than a metre to 13.00 m (cumulative) were intersected within depth range from 162.23 m to 585.3 m. Coal Seam/Zone V (1.77 m to 11.32 m), VI (8.44 m to 13.00 m) & XI (3.41 m to 5.19 m) are important considering their thickness and regional persis- tence. The regional continuity for coal seams was established for five km along strike and 2.5 km along dip direction. Exploration was completed in December, 2012. - do - Samarsingha 1;10,000 4.0 6 2788.75 - Regional exploration under G-2 stage block in Mand – Raigarh Coalfield was continued in order to establish the continuity of the regional Barakar coal seams which has already been established in the Nawagaon Block in the north and Sithra-Kurekela area in the west. The prime objective of this investigation was to assess coal resource potentiality and to carry out appraisal of CBM content About 1768.25 m of GP logging was completed. Twelve regional Barakar coal seams /zones and few local coal seams ranging in thickness from less than a meter to 11.10 m (cumulative) were intersected within depth range from 16.30 m to 738.06 m. Coal Seam / Zone- I (4.70 m to 6.26 m), IV (3.26 m to 11.10 m), VI (1.01 m to 4.16 m) are important for their thickness and regional persistence. During the period, about 5 km strike extension and 2 km dip extension have been proved. The work is in progress. (Contd.) 11-4 STATE REVIEWS Table - 3 (Contd.)

The prime objective of this investigation is to evaluate additional coal resource in the area and to carry out appraisal of CBM content. About 1902.01 m of GP logging was completed. Seven regional coal seams/zones and few local coal seams varying in thickness from less than a meter to 18.87 m (cumulative thickness) were intersected between 118.00 m and 473.40 m depths. Coal seam/zone X (cumulative thickness 3.21 m to 5.25 m), IX (cumulative thickness 1.85 m to 5.65 m) and combined coal seam zone VI and VII ( cumulative thickness 10.63 m to 18.87 m) are important for their thickness and regional persistence. During the period, about 2km strike extension and 2.5 km dip extension have been proved.

About 990.65 m of GP logging was completed. The boreholes intersected Barren Measures and Barakar Formation. Thirteen regional Barakar coal seams/ zones ranging in thickness from less than a meter to 18.94 m were intersected in the depth range from 102.05 m to 555.32 m. Seam nos/zones III (cumulative thickness 5.00 m to 18.94 m), IV (maximum cumulative thickness 9.04 m) are important for their thickness and regional persistence. Besides these, few local coal seams were also intersected in Barakar Formation, with thickness varying from less than a meter to 3.81 m, between depths 19.35 m and 508.65 m. The coal contents in Barakar Formation increase from eastern to western part of this block. The continuity of coal seams in Barakar Formation has been established over a strike length of about 6 km and 1.5 km along down dip direction. Quality-wise, seams are mostly of power grade with minor superior grade coal. The work is in progress. (Contd.) 11-5 STATE REVIEWS Table - 3 (Contd.)
