41  The Mines Act 1952: Object, Definitions, Director-General of Mines Safety, Inspection, Working Hours (Above Ground vs Below Ground), Prohibition of Women Underground, Accident Notification, Welfare and the OSH&WC Code 2020

41.1 A Special Regime for Underground and Surface Mines

Mining is among the most hazardous of all industrial activities. Workers face explosion, falling roofs, gas, dust, water inundation, electrical hazards, and the chronic effects of pneumoconiosis and silicosis. The Mines Act 1952 has been India’s central statute regulating safety, working hours, welfare and conditions of work in mines — covering both coal mining and metalliferous mining, above ground and below ground. The Act replaced the earlier Indian Mines Act 1923 and the Indian Mines Act 1901, and falls under Entry 54 / 55 of the Union List, placing mines safety firmly with the Central Government. This chapter pulls together the Act’s framework and notes the changes brought by the Occupational Safety, Health and Working Conditions (OSH&WC) Code 2020.

41.2 1 · Object, Extent and Commencement

TipObject and Scope
Aspect Detail
Year 1952 (Act 35 of 1952)
Commencement 1 July 1952
Object To regulate labour in mines — health, safety, welfare, hours of work, leave, employment of young persons and women
Extent The whole of India
Successor Code OSH&WC Code 2020
Constitutional source Union List — Entry 54 (regulation of mines and mineral development) and Entry 55 (regulation of labour and safety in mines and oilfields)

41.3 2 · Key Definitions — Section 2

TipSection 2 — Important Definitions
Term Section Meaning (in essence)
Mine 2(j) Any excavation where any operation for the purpose of searching for or obtaining minerals has been carried on, together with all works, machinery, tramways, sidings, conveyors, storage, offices, dwellings and welfare facilities
Owner 2(l) Any person who is the immediate proprietor or lessee or occupier of the mine — but not a mere mortgagee or a lessor who has parted with all interest
Agent 2(c) A person on behalf of the owner who has the charge of substantial control of the mine
Manager 2(j) The person appointed by the owner to manage the mine
Working day 2(o) The period of 24 consecutive hours beginning with the time when any worker first enters the mine
Employed 2(h) Working as the manager or as a worker in any operation of the mine
Open cast working 2(i) A quarry or excavation not below ground
Below ground All workings whose access is below the surface
Adult 2(b) A person who has completed his 18th year of age
NotePYQ trap — Working day means 24 hours, not just shift

Under Section 2(o), a “working day” is the period of 24 consecutive hours beginning with the time when any worker first enters the mine — a wider concept than a single shift. The 24-hour reference fixes the boundary for the calculation of weekly and daily hours.

41.4 3 · Inspection Machinery — The DGMS

The Directorate-General of Mines Safety (DGMS) is the central regulator under the Mines Act 1952. It is headquartered at Dhanbad, Jharkhand and operates through regional offices.

TipInspection Hierarchy under the Mines Act 1952
Section Authority Role
5 Chief Inspector of Mines Heads the inspectorate; head of DGMS — designated Director-General of Mines Safety
6 Inspectors Appointed by central government; powers of entry, examination, inspection, sampling, seizure
7-9 Powers of Chief Inspector and Inspectors Examination of records; mandatory cooperation by managers and owners
11 Certifying surgeons Medical examination of persons employed; certificate of fitness
12 Committees Tripartite committees — to advise on matters of safety, health, welfare
13 Mines Safety Committees Bipartite at each mine — to investigate and advise on safety

41.4.1 Notice and Permission

  • Section 16 — Notice to be given of opening of a new mine.
  • Section 17 — Notice to be given before fresh extension or temporary cessation.
  • Section 23Notice of accidents to be given to the Chief Inspector / Regional Inspector in case of fatal accident, serious bodily injury, dangerous occurrence, etc.

41.5 4 · Working Hours — Sections 28 to 30

The Mines Act distinguishes sharply between work above ground and work below ground.

TipWorking Hours under the Mines Act 1952
Provision Above ground Below ground
Weekly hours (Section 28) 48 hours 48 hours
Daily hours (Section 30) 9 hours 8 hours
Spread-over 12 hours 8 hours (no spread allowed)
Weekly off (Section 28) At least one day in a week At least one day in a week
Rest interval Yes — through state rules Generally no scheduled rest interval below ground (the entire shift is a single working block)
Overtime (Section 33) Twice the ordinary rate of wages Twice the ordinary rate of wages
NotePYQ anchor — 9 hours above / 8 hours below

Daily hours under the Mines Act 1952: 9 hours above ground, 8 hours below ground. The shorter underground day reflects the greater physical and respiratory hazard. NTA stems test this distinction.

41.5.1 Compensatory Day Off — Section 28A

Where a worker is required to work on his weekly rest day, he is entitled to a compensatory day off within the same month.

41.5.2 Limitation of Days — Section 28

No worker shall be required to work for more than 6 days in any week, with at least 24 consecutive hours of rest.

41.5.3 Notice of Periods of Work — Section 32

The manager of every mine must display a notice of the periods of work for each class of workers.

41.6 5 · Employment of Children and Women — Sections 40, 45, 46

TipRestrictions on Children and Women
Section Provision
40 No child below 18 years may be allowed to be present in any part of a mine which is below ground or in any open cast working in which any mining operation is being carried on
45 Prohibition of presence of persons below 18 years of age in any mine
46 Prohibition of employment of women in any part of a mine which is below ground; in any mine above ground only between 6 a.m. and 7 p.m. (subject to exemptions); with at least 11 consecutive hours of rest between two shifts
NotePYQ anchor — Section 46 absolutely prohibits women below ground

Section 46 of the Mines Act 1952 absolutely prohibits the employment of women in any part of a mine that is below ground. Above ground, women may be employed only between 6 a.m. and 7 p.m. — though state-level exemptions and the OSH&WC Code 2020 now permit night work with consent and safeguards.

41.6.1 Minimum Age — Section 40

Under the original Mines Act 1952, no child below 15 years could be employed; the 1983 amendment raised the threshold so that no person below 18 years is permitted in any mine — making mines the strictest sector for child labour even compared with the Child Labour (Prohibition and Regulation) Act 1986.

41.7 6 · Welfare Provisions — Sections 19 to 22

TipWelfare Provisions
Section Provision Trigger
19 Drinking water — adequate, wholesome All mines

NotePYQ anchor — Leave 1:20 above, 1:15 below

Earned leave under the Mines Act 1952: 1 day per 20 days worked above ground; 1 day per 15 days worked below ground. The faster leave-accumulation below ground reflects the greater physical strain.

41.11 10 · Other Important Provisions

41.13 12 · Position under the OSH&WC Code 2020

The OSH&WC Code 2020 subsumes the Mines Act 1952 along with the Factories Act 1948 and several other protective statutes.

TipMines Act 1952 vs OSH&WC Code 2020
Provision Mines Act 1952 OSH&WC Code 2020
Regulator DGMS (under Mines Act) Carried forward; DGMS as designated authority
Working hours above ground 9/day, 48/week 8/day, 48/week — subject to state rules
Working hours below ground 8/day, 48/week Retained
Women below ground Absolutely prohibited Retained as default; some safeguards-based exceptions
Women in night shift above ground 6 a.m. - 7 p.m. by default Permitted with consent and safeguards
Minimum age 18 years Continued
Leave above/below ground 1:20 / 1:15 Retained
Single registration Multiple Single across the Code
Penalties Modest Substantially enhanced

41.14 13 · Significance and Critique

  • Strictest safety regime among Indian industrial statutes — reflecting the hazard of mining work.
  • DGMS at Dhanbad among the most respected safety regulators in India.
  • Pneumoconiosis, silicosis and asbestosis — chronic respiratory conditions disproportionately affecting mine workers — recognised as notifiable diseases.
  • Critique: high incidence of accidents in unregulated and rat-hole mines; weak enforcement in some states; inadequate compensation in many cases; gender-restrictive provisions, though understandable historically, have been criticised in modern debates.
  • OSH&WC Code 2020 simplifies compliance while retaining the core protective architecture for mining workers.
