NOVEMBER 1987 GEOLOGICAL REPORT ON EXPLORATION FOR COAL JHARNA MINE & JHARNA EXTENSION BLOCK PENCH KANHAN VALLEY COALFIELD DISTRICT:CHHINDWARA, M.P.

SALIENT FEATURES

1. Name of the Block : Jharna Mine & Jharna Extension Block, Pench Kanhan Valley Coalfield, District-Chhindwara, Madhya Pradesh. 2. Block Boundary : North: Faults F7-F7 and F-16-F-16 against the respective seams except in the central part where the boundary has been taken as 200m influence distance from peripheral boreholes and working limits of seam III Top (Lower split) in Jharna Mine (In cline 21 and 22 of Ghorawari colliery). South: Faults F1-F1 and F12-F12 against the seams. East: 200 m influence distance from peripheral boreholes PKDW-1. West: Eastern boundary of East block. 3. Objectives : (i) To determine the lay and disposition of seams that occur in Barakar coal column. (ii) To identify workable seams and to estimate the proved reserves of non-coking coal, thickness-wise, depth-wise and grade-wise.

Quantum of work : a. Geological : 5.06 sq.km. Surveying b. Topographic survey including triangulation, contouring and borehole surveys. c. Drilling : 62 boreholes of PKDW & PKDM series Total meterage 15314.30 m d. Sampling : i. Band-by-band : 433.16 m coal cores from 53 boreholes analysis (CSL, CFRI, ) ii.

The dip is 5° to 9° due north. iii) A total of 17 faults, both strike and oblique in nature have been interpreted. Besides, 8 minor faults with throw less than 5.00 m have been encountered in the mine workings of seam III Top (Lower split). Out of 17 faults, F7-F7 with magnitude of throw well over 100 m in its eastern part can be considered as a major faults. However, the throw of this fault reduces in its western part. The faults F1-F1, F2-F2, F12-F12 and F13-F13 having throw varying from 35m to 60m. The remaining 12 faults with their throw raning between 5 m and 25 m. 8. Sequence of : The prevalent ranges of seam thickness and parting coal seams. with the next below seam are tabulated below:

Out of the total reserves, 26.543 million tonnes in virgin area and 3.199 million tonnes in developed area are available. A total reserves of 0.084 million tonnes of Jhama is also estimated. Team-wise distribution of net in-ritu proved reserves of non-coking coal and Jhama is furnished below.
