About 37 years ago Mine Line started as a distant dream. A Mining engineer with vision wanted to bring safe, reliable flameproof equipment to Indian coal mines. A tiny cottage industry was set up to take up the manufacture of flameproof signalling transformers, plugs and sockets and lighting transformers. The business grew rapidly in response to market demands. Today, Mine Line is the market leader in the design, manufacture, installation and service provider for the Indian underground Mining industry. All the products under manufacture are tested according to the latest IS/IEC 60079 standard and are approved by the Director General of Mine Safety.
