Back Ground:

Ministry of Coal (MOC) has allotted Machhakuta coal block on February 6, 2006 to Maharashtra State Power Generation Company Limited (MSPGCL) and

Gujarat State Electricity Corporation Limited (GSECL) for developing an opencast coal mine for power generation at linked power plants at Koradi, Chandrapur,

Parli, Paras and Bhusawal in Maharashtra and Ukai and Wanakbori in Gujarat.Mahaguj Collieries Limited (MGCL), a Joint venture of MSPGCL and GSECL

signed a MOU on December 30, 2005 to extract coal from Machhakuta Coal Block, Talcher Coalfields, Machhakuta, Tehsil Chhendipara, District Angul,

Orissa.The total estimated cost of the integrated project is about Rs. 3400 Crores.

process, zero effluent discharge.

Mode of Transport Coal transportation from CHP to washery by closed belt conveyor and washed coal to end users by rail

Railway Siding 20-km railway track to be laid up to Jarpada station (Angul - Sambalpur)

Washery Process

Raw Coal Receiving, Crushing and Storage Section

Receiving ROM coal through CHP and stocking in two stock yards of 25,000 Tonnes capacity each

Transportation of ROM coal to hoppers (2 no) of 1000 T capacity

Conveying of (-)100 mm raw coal by two parallel belts of 1200-mm width & 1000 TPH capacity each to screen-cum-crusher house to crush below

50-mm size & conveying to washery building

a.

Washery Section

Screening of (-) 50 mm raw coal at 13-mm & washing of 50-13 mm size fraction in two- product electronically controlled jigs to produce clean coal &

rejects

b.

Beneficiation & Recovery of Fines

Separation of coarser fines (-0.5 mm) from slurry in hydrocylones. Dewatering underflow slurry from hydrocylones in high frequency screens

Thickening or overflow slurry from hydrocylones in two 25 m dia thickeners.

Dewatering of thickened slurry in two nos. belt filter press

Recirculation of under & over flow waters from thickener / slime ponds in washery circuit

c.

Loading of Washed Coal

(-13mm) coal fraction and coarser fines will be mixed with & then conveyed to clean coal stock yard

d.


17 of 18 11/1/2012 10:53 AM

Reclaiming & conveying clean coal from stock pile to loading point through Rapid loading system for dispatch by Rail

Disposal of Rejects

Conveying of rejects to 2 nos. of hoppers of 300 tonne capacity each for onward use in rejects based power plant
