State-nominated coal distribution for Bihar
BSMCL groups coal distribution guidance, consumer registration routes, forms, quarterly allocation records, and official portal access in one public service page.
Overview
About coal and its distribution in Bihar
Coal is a fossil fuel. It is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams.
The coal deposits in India are primarily concentrated in the Gondwana sediments occurring mainly in the eastern and central parts of Peninsular India, although Gondwana coal deposits also occur in the north-eastern part of the country mainly in Assam and Sikkim. The Tertiary coal-bearing sediments are found in Assam, Arunachal Pradesh, Nagaland and Meghalaya.
As of now there is no coal mine in Bihar, but a coal block has been allocated to BCCL (subsidiary of CIL) in Bhagalpur and the process has been initiated to start the mine, though it will take up to 2–3 years to start coal production.
Coal consumers in the state are dependent on coal suppliers of other states. In order to eliminate dependency on handling agents, the Company has signed an agreement with a Project Management Consultant (PMC) to facilitate coal distribution in the state.
With the help of the PMC, digitization of coal distribution will benefit MSMEs and other consumers significantly, making the process transparent and efficient. The platform developed by the PMC will make it easy for the Company to manage coal distribution and eliminate dependency on handling agents.

Coal categories and practical uses
Expand each coal type to review its key behavior, industry usage, and public reference context.
01Coking Coal
These coals, when heated in the absence of air, form coherent beads, free from volatiles, with strong and porous mass, called coke.
- These have coking properties
- Mainly used in steel making and metallurgical industries
- Also used for hard coke manufacturing
02Semi Coking Coal
These coals, when heated in the absence of air, form coherent beads not strong enough to be directly fed into the blast furnace. Such coals are blended with coking coal in adequate proportion to make coke.
- These have comparatively less coking properties than coking coal
- Mainly used as blend-able coal in steel making, merchant coke manufacturing and other metallurgical industries
03Non-Coking Coal
These are coals without coking properties.
- Mainly used as thermal grade coal for power generation
- Also used for cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing, and for other heating purposes
04Washed and Beneficiated Coal
These coals have undergone the process of coal washing or coal beneficiation, resulting in value addition of coal due to reduction in ash percentage.
- Used in manufacturing of hard coke for steel making
- Beneficiated and washed non-coking coal is used mainly for power generation
- Beneficiated non-coking coal is used by cement, sponge iron and other industrial plants
05Middlings
Middlings are by-products of the three stage coal washing / beneficiation process, as a fraction of feed raw coal.
- Used for power generation
- Also used by domestic fuel plants, brick manufacturing units, cement plants, industrial plants, etc.
06Rejects
Rejects are the products of coal beneficiation process after separation of cleans and / or middlings, as a fraction of feed raw coal.
- Used for Fluidized Bed Combustion (FBC) Boilers for power generation, road repairs, briquette (domestic fuel) making, land filling, etc.
07CIL Coke / LTC Coke
CIL Coke / LTC Coke is a smokeless, environment friendly product of the Dankuni Coal Complex, obtained through low temperature carbonisation.
- Used in furnaces and kilns of industrial units
- Also used as domestic fuel by halwais, hotels, etc.
08Coal Fines / Coke Fines
These are the screened fractions of feed raw coal and LTC coke / CIL Coke respectively, obtained from the Dankuni Coal Complex and other coke oven plants.
- Used in industrial furnaces as well as for domestic purposes
09Tar / Heavy Oil / Light Oil / Soft Pitch
These are products from Dankuni Coal Complex using low temperature carbonisation of non-coking coal in vertical retorts.
- Used in furnaces and boilers of industrial plants as well as power houses, oil, dye, pharmaceutical industries, etc.

Grades of coal
Coking and semi-coking grades are defined by ash content; non-coking grades are defined by Gross Calorific Value (GCV), measured in kcal/kg.
Grades of Coking Coal
| Grade | Ash content |
|---|---|
| Steel Grade - I | Not exceeding 15% |
| Steel Grade - II | Exceeding 15% but not exceeding 18% |
| Washery Grade - I | Exceeding 18% but not exceeding 21% |
| Washery Grade - II | Exceeding 21% but not exceeding 24% |
| Washery Grade - III | Exceeding 24% but not exceeding 28% |
| Washery Grade - IV | Exceeding 28% but not exceeding 35% |
| Washery Grade - V | Exceeding 35% but not exceeding 42% |
| Washery Grade - VI | Exceeding 42% but not exceeding 49% |
Grades of Semi-coking & Weakly Coking Coal
| Grade | Ash content |
|---|---|
| Semi Coking Grade - I | Not exceeding 19% |
| Semi Coking Grade - II | Exceeding 19% but not exceeding 24% |
