Coal Worker's Pneumoconiosis (CWP)
"Black Lung Disease" Caused by Long-Term Coal Dust Exposure
Coal Worker's Pneumoconiosis (CWP) is an occupational lung disease caused by inhaling coal dust over many years. The dust accumulates in the lungs, leading to inflammation, fibrosis, and progressive breathing difficulty. In advanced stages, it can cause severe lung damage and respiratory failure.
Long-Term Mining or Dust Exposure with Breathlessness?
Early screening can prevent severe complications

CWP is preventable with proper workplace safety measures.
What is Coal Worker's Pneumoconiosis?
CWP develops when coal dust particles are inhaled and deposited in the lungs.
This leads to:
- Chronic inflammation
- Formation of black nodules in lungs
- Progressive fibrosis
Resulting in:
- Reduced lung capacity
- Impaired oxygen exchange
- Increased risk of infections
Early Signs & Symptoms
Mild Cough
Occasional Breathlessness
Fatigue
Causes & Risk Factors
Primary Cause
Inhalation of coal dust
High-Risk Occupations & Risk Factors
- Coal miners
- Industrial workers exposed to dust
- Duration of exposure
- Poor protective equipment
- Inadequate ventilation
Disease Progression
Simple CWP
Small nodules
Mild symptoms
Complicated CWP (PMF)
Large fibrotic masses
Severe lung damage
Advanced Stage
Significant airflow limitation
Oxygen dependency
End Stage Lung Disease
Respiratory failure
Lung transplant required
Diagnosis & Tests
Chest X-ray
HRCT scan
Pulmonary function tests
Occupational history assessment
Assess your occupational exposure early
Understand your lung health
Treatment Options (Before Transplant)
1. Stop Exposure
- Immediate removal from dust environment
2. Symptom Management
- Bronchodilators
- Anti-inflammatory therapy
3. Pulmonary Rehab
- Breathing exercises
4. Oxygen Therapy
- For advanced disease
When is Lung Transplant Needed?
Advanced fibrosis (PMF)
Severe breathlessness
Oxygen dependency
Prevention is the Most Effective Strategy
Workplace safety and protective measures are critical
Important Consideration: Occupational Disease
• Preventable with proper protection • Requires regular screening • Early diagnosis improves outcomes
Medical Management vs Transplant
Medical Management
Stage: Early/Moderate • Goal: Slow progression • Outcome: Limited reversal
Lung Transplant
Stage: Advanced • Goal: Replace lungs • Outcome: Life-saving
Lung Transplant Options
Single Lung Transplant
Selected cases
Double Lung Transplant
Preferred in advanced disease
