Proword: As a big country of the mineral resources, India is rich in iron ore, coal, bauxite and so on. Due to some reasons, coal in India has not been well developed and utilized. This article will take you through the current Indian coal market and how to do better investment.
South-Asian India is the second-most populous country in the world. The Himalayas are in the north. Its central part is the Gangetic Plain and south the Deccan Plateau. India is a large country with mineral resources. In addition to metal ores, its coal resources are also very rich, mainly formed in the late carboniferous Jurassic and tertiary periods.
According to the BP data, by the end of 2018, the exploration volume of anthracite, bituminous coal, sub-bituminous coal and lignite in India totaled 1013.63 billion tons, accounting for 9.6% of the world's total.

Indian coal is mainly distributed in the coal accumulation areas as below.
1. the Gondwana basin.
The sedimentary rocks of carboniferous-Permian and Triassic in the Indian peninsula are collectively referred to as the Gondwana rocks series. The rocks series is developed in many independent basins of the Indian peninsula and formed over 70 coal-bearing basins
2. the Paleogene basin.
The Paleogene coal fields in India are concentrated in Assam, Meghalaya, and Nagaland in the northeast of India. Among over 20 coal fields in this region, the Makum coalfield in Assam is the most abundant one.
3. the lignite basin.
Lignite in India is mainly distributed in the southern foothills of the Himalayas and the southeast of the Indian peninsula shield. 89% of the lignite reserves are in Tamil Nadu (mainly the Neville coalfield). The rest are distributed in Rajasthan, Gujrana, Jammu and Kashmir, Kerala, West Bengal, and central territories, etc.
4. the coking coal accumulation area in Damodar-koel valley.
The Damodar-koel valley in north-central India is a concentrated area of coking coal resources, which can be divided into four rich areas: Jharia, Bokaro, Karanpura and Raniganj.
The first three areas have larger coal reserves, and the coking coal resources in Raniganj only account for 5% of the total, while the coking quality in this area is rather high. Investors are going to get high-quality coking coal after washing and dressing.

Although coal reserves in India are relatively high, the coal industry has always encountered such difficulties like the low quality of coal, poor related equipment development as well as difficulties in land acquisition and approval. The reserves/production ratio in India is also far higher than the average of developing countries.
High reserves/production ratio means that coal in India has not been developed to the extent that it should be. Therefore, coal supply always fails to meet the rapidly increasing need for the market. Combined with accelerated infrastructure investment in recent years, the demand for coal has soared. There shows a sign of the gap between supply and demand increased year by year.
PS. The low-quality coal refers that coal in India is with lower than 4200 kcal thermal value and more than 70% of the coal produced contains over 34% ash.
Types of Coal
As an emerging economy in Asia, India's economy has maintained rapid growth for years. And the industrialization continues to be improved, which drives the consumption of coal as well as the quickly increased coal demand.
As reported, India's share of world coal production rose to 9.9 percent in 2018 from 8.8 percent in 2015. The compound annual growth rate of coal production from 2015 to 2018 has reached 4%. In terms of the world's coal production structure, India's share has been increasing along with the rising demand for coal.
As one of the most promising economies in the world, the India government is working hard in both fossil and renewable energy development. Given the production side, the coal output of the largest coal producer in India, Coal India Limited, has soared rapidly in recent years, reaching the level of 570 million tons in 2018. This data made it the largest coal manufacturer globally.

According to the degree of coalification, coal can be divided into lignite, bituminous coal, anthracite. According to the application, coal is divided into power coal and coking coal. Here is a brief introduction to the market of these two kinds of coal.
Power coal is also called thermal coal or steam coal. Power coal refers to coal that is used as a power raw material. Generally speaking, all coals for the purpose of electricity generation, locomotive fuel, boiler combustion, etc. are called power coal. The main breed is lignite, long-flame coal, gas coal, meager coal and so on.
The market for steam coal is generally in thermal power generation, industrial boilers, steam locomotives, and ships. The requirement for the quality of power coal is lower than that of any other kind of coal.
However, considering the economic benefits, there shall be certain quality requirements of power coal in different fields. The main standards are based on calorific value, ash melting point, and slagging ability. Sometimes grindability and lumpiness are used as indications.
Therefore, when selecting the thermal coal market, it is necessary to get acquainted with different thermal coal demand in different areas and make a targeted investment. This can improve the efficiency of thermal coal and increase the return of investors.
Applications of Power Coal
Coking coal is a kind of bituminous coal. Usually, coking coal has a certain cohesive property, for which it can be coked with a chamber coke oven to produce raw coal with a certain quality of carbon coke. The main types are rich coal, 1/3 coking coal, gas coal and so on.
The main market of coking coal is mainly used in metallurgy, gas production, calcium carbide production in the electric-arc furnace as a conductor and heater, briquette production and so on.
Different from thermal coal, the main indexes for evaluating the quality of coking coal include caking property, petrographic analysis, post-coking strength of single coal, the microstructure of single coal coked, rheology and expansibility indexes, etc.
Evaluation standards are different, so investors need to make different investments in different industrial fields.
Applications of Coking Coal
Steam coal stocks in Indian coal-fired power plants have been at a low level all year in 2018, while it has risen by more than 11.81 million tons since 2019, and so far this growth has not slowed down.
Since India's coal is mainly controlled by state-owned companies, this paper argues that the strong driving force affecting the Indian coal market is government policies.
As mentioned above, in recent years, India has become an emerging economy with accelerated industrialization and urbanization. In particular, to address the power shortage that has been plaguing Indians, Pralhad Joshi, India's joint minister for coal, mining and parliamentary affairs, said the country still needed coal power as its baseload for stability.
In addition, the government has taken a series of measures to increase coal production, such as relaxing mining plan approval, abolishing the central government's previous system of granting mining leases and streamlining the licensing process. The government plans to increase domestic coal production from the current 730 million tons to 1.149 million tons by 2023 to achieve zero imports of coal (except for a few irreplaceable coal).
Therefore, with the continuous progress of industrialization and urbanization in the future, India's coal consumption demand still has a huge potential.
Infrastructure Building Drives the Demand for Coal
Although India is a big coal country, the use of coal is hampered by a lack of infrastructure and the region's rainy climate. Two methods of coal processing are described to facilitate transportation and improve coal utilization efficiency.
Coal Powder Briquettes Production
What is used in coal briquettes production is coal briquetting machine. When it works, the two rollers are rotating in an opposite direction driven by a high-pressure hydraulic device. The pulverized coal is pressed into shapes needed.
This is to increase the density and firmness of materials for easier storage and transportation. According to the demand, a briquetting machine equipped with a screw feeding device can be selected.
Working Principle of Coal Briquetting Machine
Pulverized Coal Drying Process
Because of India's wet and rainy climate, the quality of coal powder is narrowed by moisture. As a kind of coal that provides power for machines, full combustion of thermal coal is very important.
A coal rotary dryer can be used to solve this problem. The coal rotary dryer works mainly based on the heat exchange between materials and hot air to dewater the materials. The drying cylinder is placed at a certain angle and is driven by the bearing. The material is dried as it goes along with the cylinder rotation.
