PRE-FEASIBILITY REPORT
FOR
NATRAJ UNDERGROUND COAL MINE PROJECT
PROPOSED CAPACITY – 0.64 MTY
1. INTRODUCTION
Natraj Underground Coal Mine Project is a part of Talcher Coalfield. Talcher
coalfield, located in river Brahmani valley to the north of Mahanadi river, constitutes
the south eastern member of lower Gondwana basin within Mahanadi valley group of
coalfields.
The coalfield spreads over 80km on the strike (east-west) and 26km on dip
rise (north-south) covering an area of about 1860 sq.km (coal bearing) of which about
201 sq.km has been explored in detail in the southern part of the coalfield. In the
northern part, an area of about 53 sq.km. has also been explored in detail. Major
portion of coalfield is situated in the district of Angul of Orissa, whereas part areas of
the coalfield spread over to Dhenkanal, Deogarh and Sambalpur districts.
Natraj Underground Project (0.64 Mty) is a proposed coal mining project.
296.47 Ha land is required for this project which has already been acquired under
Coal Bearing Area (Acquisition & Development) Act, 1957 vide Gazette Notification
No. S.O. 3687 Dt.29/11/1962. The high quality coal (B&D grade) produced through
eco-friendly fully mechanized underground mining method will be used for blending
with high ash coal of opencast mines of Talcher Coalfield for long distance power
plants so that overall ash % is less than 35%.
Continuous miner with shuttle car and side discharge loader (SDL) has been
envisaged for extraction of coal.
2. STATUS OF NATRAJ UNDERGROUND COAL MINE PROJECT
Coal Mine not yet started.
STATUS OF ENVIRONMENT CLEARANCE
EC granted vide J-11015/306/2005-IA.II (M) dated 14.07.2006 under
provisions of EIA notification, 1994.

STATUS OF FOREST CLEARANCE
Forest clearance was obtained for forest land 289.856 Ha vide letter no. 8-
73/2004 - FC dated 30-06-2009 Government of India, MoEF- FC Division.
3. NEED / JUSTIFICATION FOR THE PROJECT
The Natraj UG mine (0.64 Mty) obtained the environmental clearance under
the provision of EIA Notification, 1994 and subsequent amendments. Now as per
Gazette notification S.O 1530(E) on dated 06/04/2018, the projects obtained their
environment clearances under EIA notification, 1994 are required to obtain
environmental clearances under EIA notification, 2006. So the Form I and Brief Note
is prepared for the Revalidation of EC under EIA notification, 2006.
Further, as Nandira U/G extended its lease area to the adjoining lease hold
area of Natraj, the area of Natraj reduced from 386.68 Ha to 296.47 Ha for which
amendment in EC is required.
Public Hearing (PH) already held for the entire mine lease area (i.e.
483.227) hence the PH may be exempted for this proposal of reduction in lease area
(i.e. 296.47 Ha).
4. OBJECTIVES OF THE PROJECT:
To supply coal for blending with high ash coal of opencast mines of
Talcher coalfield for long distance power plants.
To create conditions for growth of other ancillary industries in the region.
5. LOCATION AND COMMUNICATION

7. GEOLOGY
Structural interpretation of the block is mainly based on subsurface data
because the entire area is either covered with thick soil or by laterite and Barakar
boulders. General strike of the bed is east-west with northerly dip. Local variation in
dip and strike is very common.
General direction of the dip is towards north with local swings. The amount of
dip varies from 2o-3o in the western part, 6o-7o in the central part and 4o-5o in the
north eastern corner of the block.
In all nine (9) faults have been deciphered in Natraj block. All these faults
except F8-F8 have already been proved in the adjoining Nandira block. Faults F6,
F8 and F9 have been intersected in the boreholes NTR-23, 24 and 6 respectively, the
remaining faults have been deciphered mainly on the basis of difference in the floor
