Howcoalminingactuallyworks
A growing, plain-language reference on Indian coal mining — the engineering, the regulation, and the science. Built to inform, not to sell.
This is the coking-coal sub-index of the National Coal Index — the segment Mangalam produces — not the headline all-coal figure. Published monthly by the Ministry of Coal (base year 2017-18). Source: coal.gov.in. It is a monthly index, not a live price.
The reference library.
Curated explainers and version-dated links to canonical sources — DGMS, the Ministry of Coal, the Coal Mines Regulations 2017 and the Mines Act.
The full searchable, downloadable library — Acts, rules, DGMS circulars and codes — now lives in the Regulations hub.
