Underground coal mining in India is one of the most tightly regulated industrial activities in the country, and for good reason: the hazards — gas, roof falls, dust, inrush, machinery — are serious and specific. A layered framework of law, regulation and a dedicated inspectorate exists to manage them. Understanding that framework is the starting point for understanding how a mine is actually run.
The foundation has long been the Mines Act 1952. This is the parent statute — the primary law that sets out duties of mine owners and managers, working-hour and welfare provisions, the requirement to notify and investigate accidents, and the legal authority under which detailed rules and regulations are made. Sitting under that authority is the body of subordinate legislation that governs day-to-day practice, most importantly, for coal, the Coal Mines Regulations 2017 (CMR 2017).
CMR 2017 is where the operational detail lives. It is the rulebook that classifies gassy seams by degree, mandates ventilation quantities and methane monitoring, prescribes roof-support and strata-control duties, sets out the qualifications and statutory duties of managers, engineers and safety officers, governs the type of electrical and mechanical equipment permitted in gassy conditions, and requires the systematic recording of inspections and gas readings. Where the Mines Act says what must be achieved, CMR 2017 says in concrete terms how.
Enforcing all of this is the Directorate General of Mines Safety (DGMS), the national regulator for mine safety. DGMS inspects mines, investigates accidents, approves equipment and practices for use underground, grants statutory competency certificates to mine officials, and issues technical circulars — including on ventilation — that translate the regulations into current best practice. In effect, the Act provides the powers, the Regulations provide the rules, and DGMS provides the on-the-ground authority that makes them real.
This framework is in transition, and it is worth stating accurately. As part of India's consolidation of labour law, the Mines Act 1952 is being subsumed into the Occupational Safety, Health and Working Conditions Code, 2020 (the OSH&WC Code), which came into force on 21 November 2025. The Code brings mines within a broader, unified occupational-safety statute rather than a standalone mining Act. Importantly for coal miners, the Coal Mines Regulations 2017 remain operative pending a draft replacement — so the detailed technical rulebook that governs ventilation, gas and strata control continues to apply while the new subordinate regulations under the Code are finalised. In practice this means the substance of how a mine must be run has not changed: CMR 2017 still sets the standards, and DGMS still enforces them.
For readers who want the primary sources — the Act, the Code, CMR 2017 and the relevant DGMS circulars — the site's /regulations hub gathers the statutory references in one place. This explainer is a map of the framework, not a substitute for it; the regulations themselves, and the guidance DGMS issues under them, are the authoritative word on how underground coal mining in India is conducted.
