📘 Mine Management, Legislation & General Safety (Detailed)

1. Mine Management 1.1 Introduction to Management

Evolution of Management

Classical Theories:

Taylor → Scientific Management.

Fayol → Administrative principles (14 principles).

Weber → Bureaucratic management.

Behavioral Theories:

Hawthorne Study (Elton Mayo).

McGregor’s Theory X & Theory Y.

Maslow’s Need Hierarchy.

Modern Approaches: Systems theory, Contingency theory, Situational leadership.

Scientific Management (Taylor)

1. Standard methods for tasks.

2. Scientific selection & training of workers.

3. Division of work & responsibility.

4. Harmony between workers & management.

Functions of Management → Planning, Organizing, Leading, Controlling.

Organizational Structures in Mining → Line, Line & Staff, Functional, Matrix.

1.2 Personal Management & Organizational Behaviour

Selection & Training → recruitment, job analysis, refresher training.

Leadership Styles

Autocratic → quick decisions but low morale.

Democratic → participative, high morale.

Laissez-Faire → freedom-oriented, effective with skilled workforce.

Conflict Management → sources (goals, role ambiguity, resources). Resolution by avoidance, compromise, collaboration.

Motivation Theories → Maslow, Herzberg’s Two-Factor, Expectancy theory.

Communication → Two-way (feedback essential for safety & efficiency).

1.3 Production Management

Work Study → Time & motion studies to set norms.

Mine Capacity Analysis → manpower, machinery capacity.

Production Planning → short-term (daily/weekly), long-term (life-of-mine).

Productivity → measured as Output per Man-Shift (OMS).

Ergonomics → workplace/equipment design to reduce fatigue & accidents.

1.4 Financial Management

Capital Budgeting → Payback Period, Net Present Value (NPV), Internal Rate of Return (IRR).

Cost Analysis → fixed vs variable, unit cost per ton.

Break-even Analysis → profit starts after covering fixed costs.

Working Capital Management → control of inventory, cash, receivables.

ERP in Mining → integrates HR, finance, maintenance, planning.

1.5 Mining Environment

EIA → predicts impacts before starting project.

EMP → mitigation measures.

ETP & STP → effluent & sewage treatment.

Threats → dust, noise, deforestation, subsidence, water pollution.

Reclamation →

Technical: grading, slope stabilization.

Biological: plantation, topsoil spreading.

Mine Closure Plan → progressive & final closure.

RFCTLARR Act 2013 → resettlement & rehabilitation in land acquisition.

1.6 Economic Impact of Mining

Before mining → displacement, land loss.

During mining → employment, infrastructure, but pollution.

After mining → unemployment, ghost towns if no closure plan.

1.7 Materials Management

Procurement, inventory control (ABC analysis, JIT), explosives, spare parts.

1.8 Behavioural Sciences in Mining

Application of conflict management, motivation, teamwork, morale improvement.

1.9 Industrial Accidents

Human causes → fatigue, carelessness, poor training, supervision.

Remedies → refresher training, job rotation, safety culture.

2. Legislation

Mines Act, 1952 → health, safety, working hours, employment restrictions.

Mines Rules, 1955 → medical exams, canteens, first-aid, welfare.

Metalliferous Mines Regulations, 1961 (MMR 1961) → provisions for mine safety.

CEA (Safety & Electric Supply) Regulations, 2010 → electrical safety.

Mine Vocational Training Rules, 1966 → training before mine work.

Other DGMS circulars & regulations → apply to opencast mines.

3. General Safety 3.1 Safety in Mines

Accident causes → unsafe acts, unsafe conditions.

Accident indices → Frequency Rate (FR), Severity Rate (SR).

Safety Management Plan (SMP) → SOPs, hazard management, TRAP (Take Responsibility in Accident Prevention).

Role of IT → real-time monitoring, audits, ISO standards.

3.2 Risk Management

Types → Baseline, Continuous, Issue-based.

Techniques → WRAC (Workplace Risk Assessment & Control), JSA, Risk Matrix.

Control hierarchy → Elimination → Substitution → Engineering → Admin → PPE.

TARP → Triggered Action Response Plan (preset actions during hazards).

3.3 Specific Hazards

Airborne Dust → silicosis, pneumoconiosis. Control: sprays, collectors, masks.

Mine Fires → spontaneous heating, frictional ignition, short-circuits. Controlled by sealing, inertization, firefighting.

Inrush of Water → hazards near rivers, controlled by pumping, advance boreholes.

Bench & Dump Failures → slope monitoring, geotechnical design.

Extreme Weather → heat stress, heavy rainfall, cold stress → safety measures.

Biological Hazards → snakes, insects; Chemical Hazards → toxic fumes.

Working at Heights → fall protection, harnesses, scaffolding.

3.4 Disaster & Emergency Management

Crisis Management Plan (CMP) → evacuation, communication, coordination.

Emergency Response Plan (ERP) → control room, responsibilities, equipment.

Mine Rescue → trained brigades, rescue stations, recovery work.

First Aid & Ambulance → mandatory in mines.

3.5 Occupational Diseases

Silicosis & Pneumoconiosis → lung fibrosis due to dust inhalation.

Prevention → dust suppression, dust masks, periodic medical exams.

Monitoring → dust sampling & analysis.

3.6 Miscellaneous Safety Issues

Lighting → adequate illumination, IS standards.

Sanitation & Health → potable water, toilets, canteens.

Ore Handling Safety → conveyor belt guarding, safe truck dumping, crusher enclosures.
