🧾 DETAILED NOTES
1️⃣ Introduction
Every mechanized mine requires qualified engineers to supervise the installation, maintenance, and safe working of machinery. DGMS mandates the appointment of competent engineers to ensure that all mechanical, electrical, and hydraulic systems are operated and maintained as per statutory safety standards. Such appointments are crucial for accident prevention, production continuity, and compliance with the Mines Act and CMR 2017.
2️⃣ Legal Framework
| Reference | Description |
|---|---|
| The Mines Act, 1952 – Sec. 18 & 23 | Responsibility for safe installation and operation of machinery. |
| CMR 2017 – Regulation 126 | Appointment of engineers to hold charge of machinery. |
| MMR 1961 – Regulation 125 | Engineer’s duties in metalliferous mines. |
| DGMS Circular (Mech.) No. 05/2018 | Competency and appointment of mechanical/electrical engineers. |
| DGMS Tech. Circular 02/2015 | Guidelines for maintenance and supervision (LOTO). |
3️⃣ DGMS Requirements for Appointment
- Every mine using mechanical or electrical machinery must appoint a competent engineer.
- The engineer must hold a valid DGMS-recognized degree or diploma in Mechanical/Electrical Engineering.
- The appointment must be approved and notified to DGMS and recorded in Form-B.
- Engineers are responsible for all equipment including: Conveyors, crushers, pumps, fans, winders, and HEMMs.
- Assistant Engineers may be appointed under the supervision of the Chief Engineer.
4️⃣ Duties and Responsibilities
| Duty | Description |
|---|---|
| Machinery Installation | Ensure correct installation and alignment as per design. |
| Inspection & Testing | Periodic inspection of all mechanical and electrical systems. |
| Maintenance Schedule | Plan and execute preventive maintenance programs. |
| Record Keeping | Maintain machinery logbooks and inspection registers. |
| Supervision | Oversee competent persons performing maintenance work. |
| Safety Compliance | Ensure all equipment is guarded, grounded, and safe to operate. |
| Reporting | Report any machinery failure, accident, or hazard immediately. |
5️⃣ DGMS-Approved Responsibilities
- Ensure installation drawings and manufacturer manuals are followed.
- Maintain records of overhaul and lubrication.
- Conduct load testing before commissioning new machinery.
- Certify safety guards, brakes, and limit switches.
- Train mechanics and operators in safe maintenance practices.
6️⃣ Reporting & Documentation
Engineers must maintain: Machinery Register (Form-M), Breakdown and repair reports, Test certificates (wire ropes, brakes), Log of preventive maintenance, and DGMS inspection records.
7️⃣ Consequences of Non-Compliance
❌ Operation without a competent engineer violates the Mines Act.
❌ DGMS may issue prohibition notices under Sec. 22A.
❌ Manager’s certificate may be suspended for negligence.
❌ Increased machinery breakdowns and accident risks.
