DGMS Accident Classification – Statistical, Non-Statistical & Non-Mining Accidents | DGMS Exam Notes

🧾 DETAILED NOTES

1️⃣ Introduction

Accidents in Indian mines are categorized by the Directorate General of Mines Safety (DGMS) for better safety management, prevention, and reporting. This classification system helps identify accident trends, evaluate safety performance, and implement corrective measures effectively.

2️⃣ Types of Accident Classifications by DGMS

Mining Statistical Accidents – Directly linked to mining operations.
Mining Non-Statistical Accidents – Occur inside mine premises but not due to mining operations.
Non-Mining Accidents – Occur outside the mine or unrelated to mining work.

3️⃣ Mining Statistical Accidents

These are reportable accidents under the Mines Act and relevant regulations.

Examples: Roof fall, side fall; Explosions, fires, inundation; Machinery or haulage accidents.

Reporting: Under Regulation 9 of CMR 2017 / MMR 1961 and Rule 23 of Mines Rules, 1955.

4️⃣ Mining Non-Statistical Accidents

Accidents that occur inside the mine premises but are not caused by mining operations.

Examples: Slip in canteen; Minor electrical shocks in rest areas; Fall in mine office.

Reporting: Recorded internally, not part of DGMS accident statistics.

5️⃣ Non-Mining Accidents

Accidents that occur outside mine premises, e.g., while commuting or off-duty.

Examples: Road traffic accident outside mine; Domestic injury to mine worker.

Reporting: Not required to DGMS but maintained in internal records.

6️⃣ Legal References

The Mines Act, 1952 – Sections 23 & 24
The Mines Rules, 1955 – Rules 23–29
CMR 2017 / MMR 1961 – Regulations 9–11
DGMS Circulars – Define accident classification and reporting format

7️⃣ Importance of Accident Classification

Helps DGMS maintain national mining safety index
Ensures legal compliance and transparency
Aids in root cause analysis and preventive safety planning
Encourages accountability of mine management

⚙️ QUICK ONE-LINERS (DGMS Revision Points)

DGMS classifies accidents into 3 categories.
Roof fall = Mining Statistical Accident.
Canteen injury = Non-Statistical Accident.
Road accident = Non-Mining Accident.
Reporting done under Regulation 9 of CMR/MMR.
Non-statistical = Recorded internally only.
Fatal accidents are always statistical.
DGMS prepares national safety report annually.
Non-mining accidents do not affect DGMS statistics.
Accident registers are mandatory under Rule 23 of Mines Rules.

🧮 DESCRIPTIVE MODEL QUESTION

Q. Explain the DGMS classification of accidents and distinguish between mining statistical, mining non-statistical, and non-mining accidents.

Answer:
DGMS classifies mining accidents into three types for safety monitoring. Mining Statistical accidents directly arise from mining operations like roof fall, explosion, haulage, or machinery accidents and must be reported under Regulation 9 of CMR/MMR. Mining Non-Statistical accidents occur within mine boundaries but not due to mining activity, such as slips in offices or rest shelters. Non-Mining accidents occur outside mine premises, e.g., road or domestic incidents. This classification helps DGMS in safety data analysis, preventive planning, and accident trend identification.

🧩 MCQs (25 DGMS-Based Questions — Dynamic Correct Options A–E)

Q1. How many types of accidents are classified by DGMS?

Solution: DGMS recognizes three types — Statistical, Non-Statistical, and Non-Mining.

Q2. Roof fall is classified as:

Solution: Roof fall is directly related to mining operations, hence it's a mining statistical accident.

Q3. Accident in the canteen is:

Solution: It occurs within mine premises but is not directly caused by mining operations, making it Non-Statistical.

Q4. Road accident while going to mine is:

Solution: Since it occurs outside the mine premises, it falls under the Non-Mining category.

Q5. Reporting of accidents under Mines Rules is done through:

Solution: Rule 23 of the Mines Rules, 1955 specifically mandates the notice/reporting of accidents.

Q6. Regulation 9 of CMR 2017 deals with:

Solution: Regulation 9 details the procedures for giving notice of accidents.

Q7. Accident in mine office is:

Solution: Similar to a canteen incident, it happens within the mine lease but isn't due to mining operations.

Q8. Fatal accidents are always considered:

Solution: Any fatality occurring due to mining operations is mandatorily classified as a Mining Statistical Accident.

Q9. Non-mining accident reporting is done to:

Solution: Non-mining accidents are generally not reported to DGMS, though internal records might be kept by the manager. Police might be involved depending on the nature (e.g., road accident).

Q10. Which section of the Mines Act covers accident notification?

Solution: Section 23 of the Mines Act, 1952, deals with the Notice of Accidents.

Q11. Explosion accident in mine is:

Solution: Explosions (gas or dust) are directly related to mining hazards and are Statistical accidents.

Q12. Who maintains the mine accident register?

Solution: The Mine Manager is ultimately responsible for maintaining statutory registers, including the accident register.

Q13. Slip in rest shelter is:

Solution: Occurs within mine premises but not due to direct mining activity, hence Non-Statistical.

Q14. DGMS accident data is compiled:

Solution: DGMS publishes comprehensive accident statistics annually.

Q15. Accident caused by machinery breakdown is:

Solution: Accidents involving mining machinery during operation are classified as Statistical.

Q16. Accident data is essential for:

Solution: Maintaining accurate accident records is a primary requirement for DGMS compliance and safety analysis.

Q17. Which accident affects DGMS safety index?

Solution: Only Mining Statistical accidents are included in the official safety statistics and indices published by DGMS.

Q18. Domestic accident of a miner is:

Solution: Accidents occurring at home or outside work premises are Non-Mining.

Q19. DGMS uses accident statistics to:

Solution: Accident statistics are crucial inputs for all these safety management functions of DGMS.

Q20. Inundation accident falls under:

Solution: Inundation (flooding) is a major mining hazard directly related to operations, hence Statistical.

Q21. Accident in surface quarry is:

Solution: Quarries fall under the definition of mines, and accidents related to quarrying operations are Statistical.

Q22. Accident classification helps DGMS in:

Solution: Understanding the types and causes of accidents is fundamental to effective safety planning and prevention strategies.

Q23. Electrical shock in canteen is:

Solution: It occurs within mine premises but isn't directly part of the mining/extraction process.

Q24. Slip in workshop within mine area is:

Solution: Workshops are part of the mine premises, but a simple slip might not be classified as a mining operation accident unless related to maintenance work itself.

Q25. DGMS circulars define:

Solution: DGMS issues circulars to clarify and provide guidelines on various topics, including how accidents should be classified for reporting.
