The world's 10 largest coal mines

Coal combustion produces thermal and light energy. For a long time, wood served as the primary source of energy for both household and industrial needs, but coal—burning longer than wood—was considered superior and more efficient. It is well known that the Romans used coal to heat their public baths, while the Aztecs employed it both as fuel and for decorative purposes. Early inhabitants of southern Wales used coal for cremating the dead. However, the Chinese were the world’s earliest users of coal as an energy source. A recent study published in *Science Advances* indicates that coal mining began approximately 3,600 years ago—around 1500 BCE—in northwestern China. During the Industrial Revolution, coal usage surged dramatically following Scottish inventor James Watt’s development of the steam engine. At that time, coal was burned to heat water in boilers. The resulting steam was then channeled into cylinders, where steam pressure drove pistons responsible for performing mechanical work in any machine powered by the engine. By the early 20th century, roughly half of the world’s energy came from coal. Today, despite health and environmental concerns, coal still accounts for about 35.5% of global electricity generation, with natural gas ranking second at 23%. China remains the world’s largest coal consumer, accounting for over 50% of global consumption. In terms of coal reserves, the United States leads globally, holding one-quarter of the world’s known coal reserves—and home to the two largest coal mines by reserve volume. This article introduces the world’s top ten coal mines. 1. Black Thunder Mine, USA The Black Thunder Mine lies in the southern Powder River Basin of Wyoming, USA—the world’s highest-producing coal mine. Located about 54 miles south of Gillette, Wyoming, it is owned by Arch Coal Inc., a diversified coal company headquartered in St. Louis, Missouri. A greenfield mine—meaning newly developed on previously undeveloped land—it produced an estimated 62.68 million tons of coal in 2023. Black Thunder produces low-sulfur sub-bituminous coal, typically ideal for power station fuel and requiring minimal preparation beyond crushing. Operations commenced in 1977. In 2004, it became the first U.S. coal mine to reach a cumulative shipment volume of 100 million tons (90.7 million metric tons). 2. Gevra OC Mine, India The Gevra OC Mine is situated in the Korba district of Chhattisgarh state in central India—over 1,100 miles southeast of New Delhi. Owned by South Eastern Coalfields Limited (SECL), a subsidiary of India’s state-owned Coal India Limited, the mine’s latest output estimate stands at 60 million tons annually, making it India’s largest coal mine. This region is renowned for its bituminous coal—a medium-rank coal with high calorific value. Stretching over six miles in length, Gevra OC began operations in 1981. In 2024, it received environmental clearance to expand capacity to 70 million tons per year. Its operational lifespan is projected to extend until 2036. 3. North Antelope Rochelle Mine, USA The North Antelope Rochelle Mine is located in Campbell County, Wyoming—approximately 65 miles south of Gillette—and ranks as the world’s third-highest-producing mine.

India roundup, October 14, 2021: 280 million illiterate Indians / India receives three more Rafale fighter jets

Data from India’s Ministry of Health and Family Welfare: • As of 10:00 a.m. on October 14, India reported 18,987 new COVID-19 cases and 246 new deaths; cumulative figures stood at 34,020,730 confirmed cases, 451,435 deaths, and 206,586 active cases. • Kerala reported 11,079 new cases, bringing its total to 4,820,698. • Maharashtra reported 2,219 new cases, raising its total to 6,583,896; – Among these, Mumbai recorded 477 new cases on October 13 at 10:00 a.m., bringing its cumulative total to 749,936. • Delhi reported 31 new cases, for a cumulative total of 1,439,283. • India ranks second globally in total confirmed COVID-19 cases. I. Today’s Key Developments in India 1. According to Indian media reports, Union Home Minister Amit Shah stated that India’s 280 million illiterate citizens constitute a national burden. Renowned Indian critical scholar Anand Teltumbde countered that Shah’s remark devalues the vital cognitive capacities upon which vast numbers of working people rely to sustain themselves and resist injustice. 2. Indian media reported that three additional Rafale fighter jets departed France and are scheduled to land Wednesday in Jamnagar, Gujarat—further strengthening the Indian Air Force’s military posture vis-à-vis China. These three new aircraft will raise India’s Rafale fleet to 29 jets; the original 2016 order, valued at ₹600 billion (approx. US$8 billion), comprised 36 aircraft in total. 3. This year, President Ram Nath Kovind will celebrate the Dussehra festival alongside Indian Army personnel in Dras, Ladakh—a region among the world’s coldest, where temperatures can plummet to −40°C. Breaking with tradition, the President will not attend the annual Dussehra celebrations held in the capital, New Delhi. 4. South Eastern Coalfields (SECL), a subsidiary of Coal India Limited, announced it would suspend coal supplies to non-power sectors to prioritize deliveries to power plants. Major Indian metal and cement producers are now facing severe coal shortages. 5. Insufficient coal supply for power generation has triggered widespread load-shedding across multiple Indian states. The Central Government pledged to raise daily coal-fired power generation capacity from the current 1.94 million tons to 2 million tons within five days—and asserted the coal shortage would be resolved within one month. • Power supply in New Delhi has also become strained. Local distribution companies reported operating at only half capacity due to coal shortages. Residents noted a marked increase in both frequency and duration of daily blackouts over the past week. • In Maharashtra—the state housing financial hub Mumbai—13 thermal power plants have already shut down due to coal shortages. To maintain grid stability, state utilities are purchasing electricity from other regions at triple the normal price. • Punjab has implemented scheduled load-shedding of four to five hours daily since October 9. • Several districts in Bihar have experienced cumulative blackouts exceeding 10 hours over recent days. Bihar’s state utility is now buying power from the open market at ₹20 per unit (approx. RMB 1.71)—nearly three times the government’s regulated tariff of ₹6.6 per unit (approx. RMB 0.56). • Power shortages have also emerged in Uttarakhand, where the state-wide power deficit reached 1.7 million units on October 13. Local utilities warned that load-shedding would occur in certain areas.
