Rat-Hole Mining: Issues and Concerns

Syllabus: GS3/ Mineral & Energy Resources; Distribution of Key Natural Resources

Context

  • Recently, a tragic incident occurred in the 3 Kilo area of Umrangso in Dima Hasao district of  Assam, where several workers became trapped in a coal mine due to flooding, which has brought the dangerous practice of ‘rat-hole’ mining back into the spotlight.

What is Rat Hole Mining?

Rat-Hole-Mining
  • About: It is a method of coal extraction that involves digging narrow, horizontal tunnels into the ground.
    • These tunnels are typically just wide enough for one person to crawl through and extract coal.
  • Prevalent & Causes: It is prevalent in the northeastern states of India, particularly in Meghalaya and Assam because of poverty, lack of alternative livelihood, and economic viability etc.
    • The region’s hilly terrain and the nature of its coal deposits make conventional mining methods challenging, leading to the adoption of this rudimentary technique.
    • Poor enforcement of mining laws left workers more susceptible to rat hole mining. 
  • Types: 
    • Side-Cutting: Narrow tunnels are dug horizontally into the hill slopes until the coal seam is found.
    • Box-Cutting: A rectangular opening is made, and a vertical pit is dug until the coal seam is reached. Horizontal tunnels are then created to extract the coal.
Current Laws and Regulations Related to Mining in India
Mines and Minerals Act, 1957: It governs the mining of minerals in India, including their exploration, extraction, and management.
1. Illegal mining, such as rat-hole mining, violates provisions of this Act, leading to penalties and legal action.
Coal Mines (Nationalisation) Act, 1973: Restricts mining activities to government and authorized entities.
1. Rat-hole mining is often unregulated and conducted outside this framework, making it illegal.
Environmental Protection Act, 1986 (EPA): Requires environmental clearances for mining activities. Rat-hole mining bypasses these regulations, causing severe environmental damage.
Meghalaya Mines and Minerals Policy, 2012: It was introduced to regulate mining practices in the state. However, enforcement has been weak, and rat-hole mining continues illegally.

Issues with Rat-Hole Mining

  • Environmental Impact: The unregulated nature of rat-hole mining leads to severe land degradation, deforestation, and water pollution.
    • Rivers such as Lukha and Myntdu have become too acidic to sustain aquatic life due to the high concentrations of sulphates, iron, and toxic heavy metals.
  • Health Risks: The mines lack proper ventilation, structural support, and safety measures, making them prone to collapses and flooding. Miners face diseases like lung infections from coal dust.
  • Social Problems: It causes exploitation of child labor and poorly paid workers. Also, leads to displacement of local communities.
  • Legal Violations: The National Green Tribunal (NGT) banned rat-hole mining in 2014 due to its hazardous nature and for being unscientific, although the practice remains widespread.
    • Despite the ban, illegal mining continues, driven by the demand for coal and the economic benefits it provides to local communities.

Ways to Regulate Rat-Hole Mining

  • Strengthen Legal Enforcement: Enforce the Mines and Minerals (Development and Regulation) Act, 1957 and related laws strictly. Penalize illegal mining activities and confiscate equipment used in rat-hole mining.
    • Conduct regular inspections to monitor compliance.
  • Child Labor Eradication: Strictly enforce the Child Labor (Prohibition and Regulation) Act, 1986.
    • Promote education by providing schools and scholarships in mining-affected areas.
  • Adopt Sustainable Mining Practices: Replace rat-hole mining with scientific and mechanized methods to minimize environmental damage and ensure safety.
  • Promote Alternative Livelihoods: Create employment opportunities in agriculture, handicrafts, eco-tourism, and other industries.
