4. GEOLOGICAL INFORMATIOn
 Jamuna 9&10 mine form apart of the south Rewa plateau constituting a part of
Sohagpur plain.
 The geological sequence is encountered in represented by Alluvium , Barakars ,
Talchirs and Archeans .
 Only Barakar formation consist of workable coal seam
 The general strike of coal seam is east-west.
 seam gradient is:- 1in 27 in the direction of S31°E
 The lower kotma seam has been traversed by fault ,ranging in throw up to 6m.
 There are for coal bearing in the kotma block investigate for underground mining
the seams are as follows:-
 Upper kotma
 Middle kotma
 Lower kotma 1
 Lower kotma 2
 there only lower kotma 2& middle kotma seams are economically workable.

9. METHOD OF WORKING
 Jamuna 9&10 mine has two workable coal seam
 middle kotma
 lower kotma-2
 Both seams are developed by bord and pillar method of mining.
 Now in present lower kotma -2 seam is depillaring by diagonal slicing technic in
 Panel-11A
 Panel- 16B
 In this mine coal is extracted by solid blasting of coal
