Background on Mine

The Chasnala mine is operated by Iron & Steel Company (IISCO), a subsidiary of Steel Authority of India Limited (SAIL).

According to the company's 2023 annual report, on account of the unavailability of sand for stowing, coal production at Chasnalla Colliery was suspended from November, 2020. Subsequently, on obtaining the necessary approval for stowing with a mixture of sand and bottom ash and both being available, production at Chasnalla Colliery resumed from 22nd July, 2022.

On 21st August, 2023, State Environment Impact Assessment Authority, Jharkhand, granted EC for the capacity expansion of Chasnalla Colliery up to 1.2/1.5 MTPA (Normative/Peak), along with the expansion of the coal washery of capacity 4 MTPA.

Chasnala Mining Disaster

In 1975, the mine was the site of the Chasnala mining disaster after an explosion and subsequent flooding killed 380 miners. The film Kaala Patthar depicts the tragedy, and Shaheed Smarak was built in the memory of the victims.

Coal Mine Boundaries and Methane Sources

Global Energy Monitor researchers have identified coal mine boundary/boundaries and potential sources of coal mine methane (CMM) for this mine. These research results can be used to drive CMM attribution and mitigation efforts, particularly when combined with remotely sensed methane plume locations and mine ownership data. Explore the results with the embedded map at the top of this page by clicking on the mine boundary polygon or the CMM placemarkers to reveal more details. A detailed description of this research can be found in Coal Mine Boundaries and Methane Sources. This data is also available as a downloadable companion dataset to the Global Coal Mine Tracker and the Global Methane Emitters Tracker.

ID	Notes
M1669.B1	Exact boundary coordinates were not available. The boundary was extracted from Figure 8 - Location of Chasnalla Project on Google Map of the academic paper, "A Study on Influence of Density and Viscosity of Emulsion Explosive on Its Detonation Velocity.", https://web.archive.org/web/20250401171313/https://www.researchgate.net/publication/326186928_A_Study_on_Influence_of_Density_and_Viscosity_of_Emulsion_Explosive_on_Its_Detonation_Velocity, in the September 2017. A total lease area of 3.48 sq km, based on the two underlying mouzas is given in the executive summary of the Chasnalla Colliery pre-feasibility report, https://web.archive.org/web/20250326163531/https://environmentclearance.nic.in/writereaddata/Online/TOR/02_Feb_2019_132940640LZW6L0QMAnnexureBriefPFRChasnallaColliery.pdf, created Feb 1, 2015 (PDF metadata). The area of the extracted boundary closely matches this area and is 3.32 sq km.
