Impact of the proposed Deocha-Pachami coal mine

The mineral-rich, often-arid land of Mohammad Bazar community development block, along with neighbouring Rampurhat and Nalhati blocks, is home to several hundred, mostly illegal and unregulated, mining and processing units in black stone, china clay and fire clay. According to a state government report, of about 400 stone crushing units in these three blocks, only 100 were registered as small scale industrial units. The report said that while the stone industry “provides a relatively more attractive livelihood option to a good number of people who lack education and skill, a costly trade-off is being made by them between higher earnings and serious health hazards.”

The low water retention capacity of the soil and the lack of an irrigation system allows only one crop a year, during the monsoon. This has been one of the reasons why local people depend on mining, legal or illegal, polluting or not. Still, the area witnessed repeated protests, the last major one being in 2010, when Deocha-Pachami had made headlines after the local indigenous people’s agitation against rampant pollution turned violent, leading to arson and vandalism at several crusher units.

Now, as the Deocha-Pachami project comes back in the limelight with the upcoming coal mining project, a regulated industry with the government’s direct involvement and promise of thousands of income opportunities, the organisation behind the anti-pollution movement, Birbhum Adibasi Gaonta, has split into two factions. The one led by Sunil Soren actively opposes the project and the one led by Rabin Soren is holding talks with the government over the local indigenous people’s concerns.

Asked why anyone would object if a polluting and unregulated industry is being replaced by a government initiative, Dewanganj resident Dilip Bauri told Mongabay-India, “The movement of 2010 forced the industry owners to follow some regulations to restrict pollution. The situation is better now.” To run his family of six, he farms of his own land and doubles as a helper in loading crushed stones.

At neighbouring Mathurapahari village, Hopna Tudu’s family was no less tense. They presently farm on a three-acre land plot but it is still in the name of Tudu’s father’s elder brother, who died years ago. “If the government takes this land, we will get nothing as compensation, as we have no proof of land ownership,” his wife, Sonamoni, told Mongabay-India.

There were several others who pointed out that many tribal families were living on forest land, formally recorded as government land, for several decades. These people have no land recorded in their name either.

Unwilling to enrage people with eviction and trigger a resistance movement, at least until the 2024 Lok Sabha elections, the state’s Mamata Banerjee government has decided to start mining at several hundred acres of government land, which is available and mostly free from occupation.

However, in the long run, the mining operations, for their own economic viability, will require the entire reserve to be available. The project will actually require more land beyond the reserve, as a Geological Survey of India (GSI) report has mentioned “large area needed outside block area, for external dumps as well as for access trench.”

Due to the nature of the coal reserve, a huge amount of overburden (materials such as rock and soil that lie above a coal seam) will need to be removed and then dumped outside the block.

How is the project shaping up

Sprawling across 3,400 acres (approximately 13.7 square kilometres), the mining area is made of two coal blocks – the Deocha-Pachami coal block spread over 9.7 square kilometres and the Dewanganj-Harinsinga coal block spread over 2.6 sq. km. The project, which would be implemented in a public-private partnership model, has the potential to draw investment to the tune of USD 3 billion (approximately Rs. 22,500 crore or Rs. 225 billion), according to a state government publication. There will be five end-users of the coal extracts – the thermal plants are Sagardighi Phase II, Sagardighi Phase III, Santaldih, Bakreswar and the pit head of Deocha-Pachami coal block.

There are two special characteristics that make this a unique mining area in the country as well as make it difficult to mine – high thickness of the coal seam (layers of deposits) zones that occur between thick layers of ‘partings’, or beds of noncoal rock, including very hard basaltic rocks of volcanic origin with 90-245 metre thickness.

“This is a unique type of coal deposit that has no parallel in Indian coalfields,” said a GSI report, adding that “for the construction of a large mechanised mine of phenomenal output, this is not easy to mine with the currently available technology of both underground as well as opencast mining.”

An earlier document says that in the south-central part of the coalfield, in the Deocha-Pachami area, “a super thick seam zone with maximum recorded thickness of 156-metre having 118-metre of clean coal has been recorded.” The GSI’s report described the seam as one of “enormous thickness“ that “has not been found in any of the coalfields of India.”

This high thickness of the coal seams has thrown underground mining out of option, as pointed out by the GSI report.

Notably, high seam thickness has also been cited as one of the major reasons for spontaneous heating and incidents of fire in Indian coal mines in multiple research papers in the past. The GSI’s report, too, said that mines with high seam thickness are “very vulnerable to spontaneous heating.”

According to former Coal India Limited chairman Partha Sarathi Bhattacharyya, it will take several years to reach the coal seams after removing the overburdens.

“The top layer is quite deep. In most of the mines, it usually takes about two years of opencast mining to remove the overburdens and reach the coal seam. But here it will take much longer. Removing overburdens will be a very difficult exercise due to the enormous thickness and hardness of the rocks. The state government will probably need to rope in international agencies because the required technology is not available in India,” Bhattacharyya told Mongabay-India.

A state government document said that the basaltic capping of 135 meters has its own commercial value and thus it has been included in the compensation package. Owners of 285 crusher units, apart from the price for their land and buildings, Rs. 50,000 as shifting allowance, and rehabilitation at the proposed basalt industrial park nearby, will also get 10 trucks of basalt for free every day for six months. The owners of 27 stone quarries will also get compensation for their land and buildings.

The Dewanganj-Harinsinga coal block, which is to be operationalised in the first phase according to a state government document, include Dewanganj, Nischintapur and Harinsinga.

Local residents trust newspaper vendor Basudeb Raut with the latest updates on the project. He scans every Bengali daily for news on the project, hoping for fresh information. “After the government package was reported in the media, the people started discussing it. But no one is convinced yet that it’s a good package, ” said Raut.

Samirul Islam, president of Bangla Sanskriti Mancha that has a significant presence in Birbhum district, said they would not take a stand until the local people decided on the package. “We will wait to see what the local residents have to say on the package. We’ll stand by whatever decision the local residents take,” he told Mongabay-India.

In August 2021, the WBPDCL appointed a nine-member committee, headed by actor-director Parambrata Chattopadhyay and including civil society members from the indigenous population, to supervise social work activities in areas where the work is expected to start. The social work is aimed to “gain the trust of and build confidence among the local residents for the full operationalisation of pre-mining activities,” the WBPDCL’s notice said. That committee is yet to start functioning.
