40 The Mines Act, 1952
This chapter studies the Mines Act, 1952 — the protective statute for workers in India’s coal, metal and other mines. Mines are unusually hazardous workplaces, and the Act applies a stricter regime than the Factories Act in respect of working hours, employment of women and young persons, and accident reporting. The Act has now been subsumed under the OSH Code, 2020.
40.1 Background and Genesis
India’s first mine-safety law was the Indian Mines Act, 1901, prompted by frequent disasters in colliery operations. It was replaced by the Indian Mines Act, 1923 and then by the present Mines Act, 1952, which consolidated the regime in line with ILO Convention C45 (Underground Work — Women) and the recommendations of the Royal Commission on Labour (1931).
| Year | Highlights |
|---|---|
| 1901 | First Indian Mines Act |
| 1923 | Strengthened safety and inspection regime |
| 1952 | Comprehensive new Act — present statute |
| 1957, 1959, 1983, 2011 | Major amendments — strengthened safety, women’s employment, child labour |
| 2020 | Replaced by OSH Code |
40.2 Object and Scope
The preamble states the object: “to amend and consolidate the law relating to the regulation of labour and safety in mines.” The Act covers health, safety, welfare, working hours, leave, and the employment of women and young persons in mines.
| Aim | What it covers |
|---|---|
| Safety | Strict mine-safety standards above and below ground |
| Health | Conservancy, drinking water, medical appliances, pit-head baths |
| Welfare | Canteens, rest shelters, crèches |
| Working hours and leave | Maximum hours, weekly holidays, annual leave |
| Special protection | Women (banned below ground), young persons, hazardous operations |
40.3 Key Definitions — Section 2
| Section | Term | Meaning |
|---|---|---|
| 2(j) | Mine | Any excavation where any operation for searching for or obtaining minerals is carried on; includes shafts, galleries, plants, machinery, premises and works connected with the mine |
| 2(g) | Employed | A person works as a worker, supervisor, agent or owner; expansive definition |
| 2(h) | Owner | Any person who is the immediate proprietor or lessee or occupier of the mine, or any part thereof |
| 2(c) | Agent | Any person, whether appointed as such or not, who acts on behalf of the owner and takes part in the management or control of the mine |
| 2(l) | Manager | The person responsible for the day-to-day management, control, supervision and direction of the mine |
| 2(d) | Calendar year | January 1 to December 31 |
| 2(b) | Adult, adolescent, child | Same age boundaries as the Factories Act |
The §2(j) definition of mine is broad. It includes opencast and underground mines, all surface plants and machinery connected with them, and structures used for storing minerals.
40.5 Notice of Opening, Abandonment and Discontinuance — Sections 16-17
The owner, agent or manager of every mine must give notice in writing to the Chief Inspector and District Magistrate at least 30 days before opening the mine. Similar notice is required for abandonment, discontinuance of working, reopening after discontinuance, and changes in the name or ownership.
40.6 Health Provisions — Sections 19 to 22
| Section | Provision |
|---|---|
| 19 | Drinking water — wholesome supply at suitable points |
| 20 | Conservancy — latrines and urinals separate for men and women |
| 21 | Medical appliances — first-aid boxes, ambulance room, medical staff |
| 21A | Pit-head baths and lockers — distinctive to coal mines, where workers come up coated in coal dust |
| 22 | Powers of inspectors regarding health |
The pit-head bath requirement (§21A) is one of the most distinctive welfare obligations in mining law. Workers emerging from underground are entitled to clean, hot-water bathing facilities and personal lockers — a measure of basic dignity that pre-dates the Welfare Funds.
40.7 Safety Provisions — Sections 22 to 27
The Act gives wide powers to inspectors and provides for safety committees and safety officers in larger mines.
| Section | Provision |
|---|---|
| 22 | Power of Inspector to give directions for prevention of danger |
| 22A | Power of Inspector to prohibit employment in case of danger |
| 23 | Notice of accidents — owner / agent / manager must notify the Chief Inspector of accidents and dangerous occurrences |
| 24 | Power of Government to direct an inquiry into accidents and diseases |
| 25 | Notice of certain diseases — silicosis, pneumoconiosis, manganese poisoning, etc. (Third Schedule) |
| 26 | Power to call for returns and reports |
| 27 | Cost of inquiries |
The Mines Rules, 1955 and the Coal Mines Regulations, 2017 (replacing 1957) carry the detailed safety standards. Modern Indian mining safety is shaped by the post-1975 Tripartite National Conference on Safety in Mines, held periodically.
40.8 Welfare Provisions — Sections 41 to 47
| Section | Provision | Threshold |
|---|---|---|
| 41 | Power of state government to make rules for welfare | — |
| 42 | First-aid — adequate boxes and trained personnel | All mines |
| 43 | Shelters / rest rooms / lunch rooms | 150+ workers |
| 44 | Pit-head baths | All coal and other prescribed mines |
| 45 | Crèches | 50+ women employed (lower than the Factories Act’s 30) |
| 46 | Canteens | 250+ workers |
| 47 | Welfare officers | 500+ workers |
The threshold for crèches (50 women) and the canteen (250 workers) closely parallel the Factories Act, but are read with the more demanding mining context.
40.9 Working Hours — Sections 28 to 39
The Mines Act draws a sharp distinction between above-ground and below-ground work. Below-ground work — being more hazardous — is subject to stricter limits.
| Provision | Above ground | Below ground |
|---|---|---|
| Weekly hours (§28) | 48 hours | 48 hours |
| Daily hours (§30) | 9 hours | 8 hours |
| Spread-over (§30A) | 12 hours | (Strict 8-hour cap; no spread-over relief) |
| Weekly day off (§28) | One day in every 7 | One day in every 7 |
| Compensatory holiday (§29) | Within 2 months if missed | Within 2 months if missed |
| Night shifts (§30) | Permitted with rest interval | More restricted |
| Overtime (§33) | Twice the ordinary rate | Twice the ordinary rate |
Below ground, the 8-hour day cap is hard — there is no provision for spread-over relaxation. The harsher conditions and lower oxygen at depth justify the stricter limit.
40.10 Restrictions on Employment — Sections 40 to 48
| Section | Provision |
|---|---|
| 40 | No person below 18 years to be employed in any mine — above or below ground. (Stricter than Factories Act.) |
| 41 | Apprentices and trainees — only after medical fitness certification |
| 43 | Disclosure of age — register of workers with age proof |
| 45 | Power to require medical examination |
| 46 | No woman below ground; women above ground only between 6 a.m. and 7 p.m. (subject to one-hour gap between shifts) |
The complete prohibition on workers under 18 — whether above or below ground — is one of the most stringent age restrictions in Indian labour law. The Factories Act allows adolescents (15–18) with a fitness certificate; the Mines Act does not.
The §46 complete ban on women below ground tracks ILO Convention C45 (1935). Recent debates and 2019 administrative changes have allowed women to work below ground in selected non-coal mines with safeguards.
40.11 Annual Leave with Wages — Sections 51 to 56
| Provision | Above ground | Below ground |
|---|---|---|
| Qualifying days (§52) | 240 days of work in calendar year | 190 days of work in calendar year |
| Adult leave rate (§52) | 1 day for every 20 days worked | 1 day for every 15 days worked |
| Child / adolescent leave rate | 1 day for every 15 days worked | 1 day for every 15 days worked |
| Carry-over | 30 days for adults; 40 for children | Same |
| Wages during leave | Daily average of basic wages and DA | Same |
The lower qualifying days (190 below ground vs 240 above ground) and the more generous leave rate below ground reflect the harsher conditions of underground work.
40.12 Notice of Accidents and Occupational Diseases — Sections 23 to 25
| Section | Subject |
|---|---|
| 23 | Notice of accidents — every fatal accident or accident causing serious bodily injury must be reported to the Chief Inspector and the District Magistrate |
| 23A | Notice of dangerous occurrences (e.g. explosion, fire, inrush of water) |
| 24 | Power of government to direct inquiry |
| 25 | Notice of certain diseases — silicosis, asbestosis, pneumoconiosis, manganese poisoning, etc. listed in the Third Schedule |
Mine accidents — particularly the recurring tragedies in coal mines — have shaped much of India’s mine-safety jurisprudence. The 1975 Chasnala mine disaster (375 killed in a flooded coal mine in Jharkhand) and the 1973 Dhanbad gas explosions are the reference points.
40.13 Penalties — Sections 64 to 79
| Section | Offence | Penalty |
|---|---|---|
| 64 | Failure to give notice of accident | Fine up to ₹2,000 |
| 65 | Use of false certificate | Imprisonment up to 6 months or fine up to ₹2,000 |
| 66 | Omission of name from register | Fine up to ₹500 |
| 67 | Employment of person under 18 in contravention | Fine up to ₹2,000 |
| 68 | Failure to provide canteens, crèches, etc. | Fine up to ₹2,000 |
| 72 | Disregard of Inspector’s lawful orders | Imprisonment up to 3 months or fine up to ₹1,000 |
| 72A | Knowingly causing danger by acts or omissions | Imprisonment up to 2 years or fine up to ₹5,000 |
| 73 | Penalty for offences against the Act not specifically provided for | Fine up to ₹1,000 |
| 75 | Power of court to require precautions to be taken | |
| 79 | Limitation of prosecutions | Within 6 months |
The penalties are modest by modern standards. The OSH Code, 2020 has revised them upward.
40.14 Mines Welfare Funds — A Note
Welfare of mineworkers is supported by a system of cess-funded welfare funds, separate from the Mines Act itself. Each fund is collected through a small cess on the mineral output and applied to housing, health, education, recreation and emergency assistance for mineworkers.
| Fund | Established by |
|---|---|
| Mica Mines Labour Welfare Fund | Mica Mines Labour Welfare Fund Act, 1946 |
| Coal Mines Labour Welfare Fund | Coal Mines Labour Welfare Fund Act, 1947 (now part of Coal Mines Provident Fund and Miscellaneous Provisions Act, 1948) |
| Limestone and Dolomite Mines Labour Welfare Fund | LDMLWF Act, 1972 |
| Iron Ore, Manganese Ore and Chrome Ore Mines Labour Welfare Cess Act, 1976 | Cess for the Welfare Fund |
| Beedi Workers Welfare Fund | Beedi Workers Welfare Fund Act, 1976 |
| Building and Other Construction Workers Welfare Cess Act, 1996 | BOCW workers (chapter 43) |
The funds are administered by the Labour Welfare Organisation of the Ministry of Labour and Employment. Most have been consolidated under the Code on Social Security, 2020.
40.15 Position under the OSH Code, 2020
The OSH Code, 2020 has repealed the Mines Act, 1952 and folded its provisions into the consolidated framework. Key continuities and changes:
| Element | Mines Act 1952 | OSH Code 2020 |
|---|---|---|
| Coverage | All mines as defined | Continued; integrated with general OSH framework |
| Below-ground 8-hour cap | Yes | Retained |
| Women below ground | Prohibited | Permitted in selected non-coal mines with consent and safeguards (per 2019 amendments and OSH Code rules) |
| Welfare officer threshold | 500+ workers | Retained / revised by rules |
| Annual leave qualification | 190 / 240 days | Reduced to 180 days (general OSH Code rule) |
| Penalties | Modest | Revised upward; compounding allowed |
| Single registration | Separate | Single registration across labour codes |
| Enforcement | DGMS continues to enforce mining provisions | DGMS continues |
The Mines Act has thus been subsumed but its substantive content survives in the OSH Code with modernised features.
40.16 Significance of the Act
The Mines Act, 1952 has been the foundational safety and welfare statute for the most hazardous of Indian workplaces. Three impacts stand out.
- It established stricter standards for mining than for general factory work — recognising the unique risks of mineral extraction.
- It produced India’s first comprehensive occupational-disease notification regime — silicosis, pneumoconiosis, manganese poisoning are listed conditions.
- It created the DGMS — one of the earliest sector-specific labour-safety regulators in the world.
