NMDC ltd has plans to source power for its proposed 7.0 MTPA Bailadila Iron Ore Mine Deposit No 4 at Bhansi near Bacheli at Dantewada District in south Bastar from Chhttisgarh State Power Distribution Company ltd (CSPDCl) through its 33 Kv sub station located at Kirandul using suitable overhead lines, officials informed.
Notably, CSPDCl is already supplying electricity to NMDC’s Bailadila projects. Power supply is also required by NMDC for operating mines, Crushing Plant, Secondary Crushing plant, tertiary crushing plant, Screening plant, Stacking , Reclaiming, loading plant, Service Centre and Township, officials informed.
Based on the various loads involved, it is estimated that Maximum demand requirement shall be approx. 6 MVA to meet the 7 MTPA productions from the Deposit 4 mine.
It is proposed to have one 33 KV substation at Hill -Top to meet the nearby loads of mines, Crushing plant, Secondary Crushing plant, Tertiary crushing plant, Service centre etc.
The supply voltage to these load centers can be at 6.6 Kv , they stated. The main receiving 33 KV receiving substation is proposed at foot hill to meet the loads of remaining sections i.e Screening plant, Stacking , Reclaiming, loading plant, water pumping ,Township etc.
The substations will have PlC & SCADA systems which can be interlinked on fiber optic / wireless network. Automatic Power factor control systems are also to be envisaged at major load centers including the substations. Notably, NMDC proposes for mining the Deposit number 4 iron ore mine with a production capacity of 7.0 MTPA in the mine lease area of 646.596 hectares.
Notably, NMDC's iron ore requirement for its upcoming steel plant at Nagarnar would be 5 MTPA. The exploration work was done at Bailadila Deposit No. 4 by NMDC in the year back in 1972-74. The ore reserves were proved by detailed exploration activities. The Deposit 4 has a production capacity of 7.0 MTPA and spread in a mining lease area of 646.596 hectares.
In addition to the mining lease area, 95.13 hectares forest land is identified for development of infrastructure such as downhill conveyor, screening plant, loading plant and approach road etc. Further, 50 hectares of non-forest land is also required for installation of railway stock yard,
administrative building, loading plant (part), tailing dam, STP and township etc. The existing iron ore production from other Bailadila mines is catering to requirements of large steel plants and also to local sponge iron/pellet plants in Chhattisgarh.
Mining plan along with progressive mine closure plan has been approved by Indian Bureau of Mines (IBM), for production capacity of 7.0 MTPA vide their letter no: No 314(3)/2012-MCCM (CZ)/MP-19 dated July 26, 2013, officials informed.
Notably, NMDC is operating iron ore mines at Bailadila Complex in South Bastar Dantewada District Chhattisgarh and is having long term commitment for supply of iron ore to major steel plants across the country.
Hence, J.V. Company between NMDC and Chhattisgarh Mineral Development Corporation (CMDC) i.e NMDC-CMDC (NCl) was formed for development of a new deposit in the already prospected areas i.e Bailadila Deposit-4 with a production capacity of 7 MTPA for meeting the iron ore requirement of Steel plant of NMDC at Nagarnar, near Jagdalpur.
