Kangra Coal Proprietary Limited v Minister of Minerals and Energy and Others

Kangra Coal Proprietary Limited applied in terms of Regulation 4.16(2) of the Mines Health and Safety Act 29 of 1996 for permission to conduct blasting operations within 500 metres of residential dwellings near its mining operations in Mpumalanga. The application was supported by risk assessments, structural surveys of affected dwellings, expert blasting designs, mitigation measures (including evacuation during blasting, reduced charge mass, vibration limits, pre- and post-blast inspections), and agreements to repair damage or compensate homeowners. The Acting Principal Inspector and Chief Inspector of Mines refused approval unless Kangra relocated all affected dwellings outside the 500m radius. Kangra appealed to the Labour Court under section 58(1) of the MHSA, arguing that it had demonstrated the absence of ‘significant risk’ and that relocation was unnecessary.

The appeal was dismissed with costs. The decision of the Chief Inspector of Mines refusing permission to blast within 500 metres without relocation of the dwellings was upheld.

This case clarifies the interpretation of ‘significant risk’ under the Mines Health and Safety Act, confirming that regulators must assess risk by balancing both probability and consequences of harm. It affirms a precautionary approach to mine safety and underscores the importance of post-incident risk management, particularly where vulnerable communities and substandard housing are involved. The judgment reinforces the authority of mine inspectors to refuse approvals where residual safety risks remain.
