Overview :

Jayant OCP(a 10 MTY Project) of NCL is one of the oldest mine of Singrauli area with dragline working, in which the excavation started in the year 1976-77 and approximate depth of the mine is now approaching 180m. The project has an environmental clearance of 15.5 MTY. An expansion project report of Jayant OCP for 20 MYTPA is under consideration before CIL board. It has achieved a peak production level of 15.50 MT in the year 2010-11.

The project is administratively under NCL and is presently headed by General Manager.

Brief History :

  • The original PR for Singrauli-I (Jayant) for a Targeted production of 3.05MT was sanctioned by Govt of India in 1962.
  • Operations were suspended in 1964 due to limited demand of coal.
  • Re-appraisal of Singrauli-I was done in 1972 with capital expenditure estimated at 20.61 Cr.
  • Feasibility study report with Soviet Experts in 1974 identified Jayant project with rated capacity of 10 MTY.
  • Presently Jayant OCP is a 10 MTY project in which the excavation started in the year 1976-77 and the approximate depth of the mine is approaching 180 meters. The project is 3.6 km wide along strike length and the dip side length is 3.5 km, whereas the average lead of the mine is 3.5 km.See More

Details of Coal Seam at Jayant Mine :

Seam description Avg. Thickness Grade of Coal
Purewa Top 6-7 m G-10
Purewa Bottom 11-13 m G-10
Turra 17-18 m G-7
Future Plans:
  • An expansion project report of Jayant OCP for 20 MYTPA is under consideration before CIL board. An additional Land of 462 Ha. Will be required for the purpose and process of land acquisition is in progress. Environmental clearance will be obtained accordingly.
  • Year Wise Coal production of Jayant Project for next Five Years under the ambitious 1BT Production plan of CIL is as follows :
  2015-16 (BE) 2016-17 (BE) 2017-18 (BE) 2018-19 (BE) 2019-20 (BE)
Existing Mine 13.00 13.00 12.00 12.00 12.00
Expansion Project 0.00 1.00 3.00 4.00 6.00
  • Incremental CHP of 15 MTPA Capacity, having crushing output of (-)100 mm size, is considered in the expansion project , thus increasing the despatch capacity upto 25 MTPA. It is also envisaged to modify the existing CHP for crushing output of (-)100 mm size.
  • Deployment of surface Miner has been considered for Jayant Project, which is scheduled during December’ 2015.
  • Feasibility of Coal Washing for improving the quality of Coal is also being explored.

Mining Methodology:

The Method of Work adopted at Jayant Project is Dragline-cum-Shovel-Dumper combination mining. Two flanks namely East and West are operating in the length of 1.8 KM and 2.0 KM respectively with a total length of 3.8 KM. The Coal Seams are dipping towards North and the Sump is located at intersection point of both flanks.

An average of 80 meter width is taken in the Dragline Cut with average working height 40 meters and rest of the parting i.e. 15-20 meters is taken by Shovel-Dumper combination

There are two Draglines 15/90 and 24/96 in West side and two nos. 24/96 Draglines are in the Eastern side. Draglines are operated in Horizontal Tandem extended Bench method (i.e. Draglines are on same Level), as per the balancing diagram proposed by CMPDIL.

There are two Draglines 15/90 and 24/96 in West side and two nos. 24/96 Draglines are in the Eastern side. Draglines are operated in Horizontal Tandem extended Bench method (i.e. Draglines are on same Level), as per the balancing diagram proposed by CMPDIL.

There are two Mid-Entries i.e. East and West Mid-Entry apart from Central Entry to mine out Turra Seam. These Entries facilitate the Draglines to operate continuously without idling while taking the new Seating in the next Cut. Also the Lead of Dumpers reduces with the provision of Mid-Entries

The OB cover varies from 10 meter at Outcrop to about 180 meter peak. Shovel and Dumper combination are deployed for Turra, Purewa Top and Bottom Coal Seam and all OB benches beyond the dragline benches.

In the Shovel-Dumper combination 40 meter width and 15 meter height is taken as a standard practice. Average working height of dragline bench is 32 to 35 meters with a cut width of 80 meters.

Environmental Consciousness:

The project satisfies all the legal provisions and environmental conditions. 40 MLD capacity different effluent treatment plant and 4 MLD capacity Sewerage Treatment Plant has been installed in the project. It contributes in making the project a clean producing unit. An equal emphasis is given in raising the greenery of the area and in this respect and about 2848437 plants have been planted till date. The project also care for the society in and around the mine premises for which substantial amount is spend on community development works including health camps and schools.

In order to ensure zero discharge of mine water into the outside surroundings, the excess treated water (balance after re-use in tanker filling for dust suppression) carried to HEC reservoir (Cap. 4400 cum). A high capacity pump has been installed at Mine ETP and a pipe line from mine ETP to HEC tank, situated at hill top, has been laid, to achieve a mile stone towards zero discharge
