Jharia coalfield is a large coal field located in the east of India in Jharia , Dhanbad, Jharkhand . Jharia represents the largest coal reserves in India having estimated reserves of 19.4 billion tonnes of coking coal. The coalfield is an important contributor to the local economy, employing much of the local population either directly or indirectly.
54-417: The fields have suffered a coal bed fire since at least 1916, resulting in 37 millions tons of coal consumed by the fire, and significant ground subsidence and water and air pollution in local communities including the city of Jharia . The resulting pollution has led to a government agency designated for moving local populations, however, little progress has been made in the relocation. The coal field lies in

In the year 1920, when he held a large public charity event and a yagna at Sinugra. At the time of this event, Seth Khora Ramji was honoured by Maharao of Cutch, Sir Khengarji III Sawai Bahadur , who sent him a Paghdi by hands of royal messenger. Further, at Mathura he along with Jetha Lira Jethwa of Sinugra had built and donated

The several mines were owned jointly as HUF by the family of 5 brothers of Seth Khora Ramji, which were divided among the family mutually after his death. Ambalal Khora also carried on father's legacy as a railway contractor, who died in a railway accident. His eldest son Karamshi Khora took over
216-630: A comparative analysis of various land subsidence monitoring techniques. The results indicated that InSAR offered the highest coverage, lowest annual cost per point of information and the highest point density. Additionally, they found that, aside from continuous acquisition systems typically installed in areas with rapid subsidence, InSAR had the highest measurement frequencies. In contrast, leveling, non-permanent GNSS, and non-permanent extensometers generally provided only one or two measurements per year. These methods project future land subsidence trends by extrapolating from existing data, treating subsidence as

As the cumulative moisture deficit is reversed, which can last up to 25 years, the surface level around the tree will rise and expand laterally. That often damages buildings unless the foundations have been strengthened or designed to cope with
540-736: A perceived lackadaisical attitude towards the safety of the people of Jharia. Heavy fumes emitted by the fires lead to severe health problems such as breathing disorders and skin diseases among the local population. Subsidence Subsidence is a general term for downward vertical movement of the Earth's surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement . Processes that lead to subsidence include dissolution of underlying carbonate rock by groundwater ; gradual compaction of sediments ; withdrawal of fluid lava from beneath
594-437: A result of increased effective stress . In this way, land subsidence has the potential of becoming self-perpetuating, having rates up to 5 cm/yr. Water management used to be tuned primarily to factors such as crop optimization but, to varying extents, avoiding subsidence has come to be taken into account as well. When differential stresses exist in the Earth, these can be accommodated either by geological faulting in

The first fire was detected in 1916 at Bhowrah colliery owned by Eastern Coal Co Limited. First incidence of fire was reported on 1916 in XIV seam of Bhowra Colliery. Since then a number of fires have occurred in U/G, Opencast and in OCM debris. Due to unscientific mining undergroung fire spread to other mines According to records, almost fifteen years later after first fire incident occurred at Bhowra Collliery owned by Eastern Coal Company, one of

Mining-induced subsidence is nearly always very localized to the surface above the mined area, plus a margin around the outside. The vertical magnitude of the subsidence itself typically does not cause problems, except in the case of drainage (including natural drainage)–rather, it
864-415: Is the associated surface compressive and tensile strains, curvature, tilts and horizontal displacement that are the cause of the worst damage to the natural environment, buildings and infrastructure. Where mining activity is planned, mining-induced subsidence can be successfully managed if there is co-operation from all of the stakeholders. This is accomplished through a combination of careful mine planning,

Jharia coal mines are India's most important storehouse of prime coke coal used in blast furnaces, it consists of 23 large underground and nine large open cast mines. The mining activities in these coalfields started in 1894 and had really intensified in 1925. The first Indians to arrive and break monopoly of British in Coal mining were Gujarati railway contractors from Kutch some of whom decided to plunge into
972-437: The Jharia coal fields were being exploited by Europeans and Seth Khora Ramji was first Indian to seize the opportunity. He purchased two collieries to begin with. Gradually others from Kutch and Gujarat followed suit and now Jharia has been changed into a Gujarati settlement with about 50 Kutchi out of 92 Gujarati collieries proprietors with Seth Khora Ramji as head of them all. He is now sole proprietor of two collieries and
1026-409: The area. The subsidence was brought to a halt when secondary recovery wells pumped enough water into the oil reservoir to stabilize it. Land subsidence can occur in various ways during an earthquake. Large areas of land can subside drastically during an earthquake because of offset along fault lines. Land subsidence can also occur as a result of settling and compacting of unconsolidated sediment from

1404-507: The effect. High buildings can create land subsidence by pressing the soil beneath with their weight. The problem is already felt in New York City , San Francisco Bay Area , Lagos . Land subsidence leads to the lowering of the ground surface, altering the topography. This elevation reduction increases the risk of flooding , particularly in river flood plains and delta areas. Earth fissures are linear fractures that appear on
1458-673: The excessive extraction of groundwater, making it a growing problem throughout the world. Groundwater fluctuations can also indirectly affect the decay of organic material. The habitation of lowlands , such as coastal or delta plains, requires drainage . The resulting aeration of the soil leads to the oxidation of its organic components, such as peat , and this decomposition process may cause significant land subsidence. This applies especially when groundwater levels are periodically adapted to subsidence, in order to maintain desired unsaturated zone depths, exposing more and more peat to oxygen. In addition to this, drained soils consolidate as

His Khas Jharia mine was one of the firsts to collapse in underground fire in 1930. Two of his collieries, Khas Jharia and Golden Jharia, which worked on maximum 260-foot-deep shafts, collapsed due to now infamous underground fires, in which their house and bungalow also collapsed on 8 November 1930, causing 18 feet subsidence and widespread destruction. The fire never stopped despite sincere efforts by mines department and railway authorities and in 1933 flaming crevasses lead to exodus of many residents. The 1934 Nepal–Bihar earthquake led to further spread of fire and by 1938

Karamshi Khora was among the dignitaries, who shared dais in historic All India Trade Union Congress meeting held at Jharia in 1928 by prominent labor leaders like Swami Viswananda and Swami Darsanananda. It was hosted by Ramjush Agarwalla and diginatories present on dais were Karamshi Khora, D. D. Thacker , Hardevdas Aagarwal, Chhaganlal Karamshi Parekh , Babu Shyam Sunder Chakravarty, Keshavji Pitambar, Diwan Chaman Lall , Madhavji Jiwan, Savitri Devi and others. Several after his death two of his collieries, Khas Jharia & Golden Jharia, which worked on maximum 260-foot-deep shafts, collapsed due to now infamous underground fires, in which their house and bungalow also collapsed on 8 November 1930, causing 18 feet subsidence and widespread destruction. The coal mines at that time were run by his sons Karamshi Khora, Ambalal Khora and others.

He rose to such a height by 1920 and became Seth Khora Ramji from Khora Ramji that British had to mention his name in Encyclopaedia of Bengal, Bihar & Orissa. He had studied up to fourth standard in his native village school but still managed to build railway bridges which requires technical knowledge and mathematical calculations. Khora Ramji and Brothers established collieries at Khas Jharia , Jeenagora , Jamadoba , Balihari , Fatehpur, Gareria, Bansjora & Bagadih. In Pure Jharia Colliery Khora Ramji and brothers were partners with Diwan Bahadur D.D. Thacker . Khora Ramji
2052-556: The public in general. Pumping of groundwater or petroleum has led to subsidence of as much as 9 meters (30 ft) in many locations around the world and incurring costs measured in hundreds of millions of US dollars. Land subsidence caused by groundwater withdrawal will likely increase in occurrence and related damages, primarily due to global population and economic growth, which will continue to drive higher groundwater demand. Subsidence frequently causes major problems in karst terrains, where dissolution of limestone by fluid flow in
2106-525: The shaking of an earthquake. The Geospatial Information Authority of Japan reported immediate subsidence caused by the 2011 Tōhoku earthquake . In Northern Japan, subsidence of 0.50 m (1.64 ft) was observed on the coast of the Pacific Ocean in Miyako , Tōhoku , while Rikuzentakata, Iwate measured 0.84 m (2.75 ft). In the south at Sōma, Fukushima , 0.29 m (0.95 ft)
2160-620: The subsurface creates voids (i.e., caves ). If the roof of a void becomes too weak, it can collapse and the overlying rock and earth will fall into the space, causing subsidence at the surface. This type of subsidence can cause sinkholes which can be many hundreds of meters deep. Several types of sub-surface mining , and specifically methods which intentionally cause the extracted void to collapse (such as pillar extraction, longwall mining and any metalliferous mining method which uses "caving" such as "block caving" or "sub-level caving") will result in surface subsidence. Mining-induced subsidence

If natural gas is extracted from a natural gas field the initial pressure (up to 60 MPa (600 bar )) in the field will drop over the years. The pressure helps support the soil layers above the field. If the gas is extracted, the overburden pressure sediment compacts and may lead to earthquakes and subsidence at

When these angular distortions exceed certain values, the structures can become damaged, resulting in issues such as tilting or cracking. Land subsidence causes vertical displacements (subsidence or uplift). Although horizontal displacements also occur, they are generally less significant. The following are field methods used to measure vertical and horizontal displacements in subsiding areas: Tomás et al. conducted

If building foundations are above the level reached by seasonal drying, they move, possibly resulting in damage to the building in the form of tapering cracks. Trees and other vegetation can have a significant local effect on seasonal drying of soils. Over
2430-665: The volume of groundwater extraction , and clay content. This model assumes that changes in piezometric levels affecting aquifers and aquitards occur only in the vertical direction. It allows for subsidence calculations at a specific point using only vertical soil parameters. Quasi-three-dimensional seepage models apply Terzaghi 's one-dimensional consolidation equation to estimate subsidence, integrating some aspects of three-dimensional effects. The fully coupled three-dimensional model simulates water flow in three dimensions and calculates subsidence using Biot's three-dimensional consolidation theory. Machine learning has become
