SALIENT FEATURES

INTRODUCTION

Dulanga Block was allocated to NTPC under Captive mode. It is located in the Ib Valley Coalfield lying in the south eastern extremity of NW-SE trending master basin belt of Sone Mahanadi valley. The block falls in Sundergarh district of Odisha state. This block is contiguous to Manoharpur block which is owned by OPGC in the North West side.

Dulanga coal block is about 55 km South-West from of Sundargarh District headquarters and about 10 Km North-West of Jharsuguda District headquarters. It is connected by Tar Road with Hemgir – Jharsuguda national highway. The nearest rail head is Hemgir Railway Station at a distance of about 28 Km.

The topography of the block is highly undulating and rugged in nature. Central and southern parts of the area are marked by higher elevation exhibiting hillocks and ridges whereas eastern side of the block is more or less flat in nature. Drainage of the block is mainly controlled by Garia Nala, Baidhara Nala and Nala- B.

Revised Mining Plan and Mine Closure Plan of Dulanga block is already approved by Ministry of Coal for a targeted capacity of 7 MTPA. Environment Clearance has been already accorded by MoEF. Stage-I Forest clearance has also been granted by MoEF and Stage-II compliance is under progress. Notifications under CBA Act & part notification under LA Act for acquisition of land have been completed.

GEOLOGY

Total area of Dulanga coal block is 654.11 ha. General geology displays complete sequence of Lower Gondwana rocks from Talchir to Kamthi. General strike of the beds varies from N20°W-S20°E to N40°W-S40°E with southwesterly 5° to 10° dip. The block is free from major tectonic disturbances but one of the strike fault namely F1 - F1 as deciphered from the subsurface data, divides the block into two unequal parts. Besides this two more faults of F2 - F2 & F3 – F3 are of very small magnitude.

Detail exploration in Dulanga Block has revealed the presence of coal bearing horizons belonging to Karharbari & Barakar Formations. However, major part of

the economic coal resources is confined to Barakar only. Three major coal seams occur in this block viz. Parkhani, Lajkura and Rampur, in descending order. In Karharbari Formation very thin coal bands are seen with no economic potentiality in the block.

Total estimated mineable reserves within the block is 152.05 Million Tonnes and corresponding total overburden/ interburden is estimated as 394 million cubic meters. Strip ratio worked out as 2.59 m3/t.

MDO SCOPE OF WORK

MDO shall undertake the land acquisition, construction of R&R Colony, mine development and operation. MDO is expected to acquire the land, construct the R&R Colony, develop, operate and maintain the mine to ensure supply of coal to NTPC. This shall involve interalia interaction with PAPs & State Government relating to land acquisition and R&R, physical possession of land, excavation of various rocks/earth cutting by mechanised means, loading, transportation, dumping, dozing, mining of coal, crushing the coal to a pre-determined size, leveling at OB dumping site to ensure progressive mine closure, creation of related infrastructure facilities like equipment workshop, laying of power transmission line from Darlipalli STPP/DISCOM to Main Receiving Station, electrical substations, coal handling plant, Loading Silo, pumping arrangements, haul road maintenance etc and delivery of crushed coal to NTPC at the pre- determined delivery point. MDO will be required to abide by all statutory rules, regulation and laws as applicable.

NTPC’s SCOPE OF WORK

NTPC’s scope of work includes providing Geological Report of the block, Approved Revised Mining Plan and Approved EIA/EMP. Notifications under CBA & LA Act for acquiring the land which have already been completed, Stage-I forest Clearance etc., shall also be provided. NTPC shall make payment towards land acquisition, various grants under R&R. For construction of R&R Colony, NTPC shall pay a fixed amount to MDO.
