The renovated underground Mock-Up Coal Mine of BITM, Kolkata inaugurated on April 4, 2008 with ‘Light & Sound Show’, provides an experience of the real life thrills inside a coal mine. The visitors have the knowledge of how does a coal mine look and what is happening below the ground. The air circulation and illumination of a coal mine, in spite of its great depth and extreme darkness, are presented here. One can have an idea of the coal cutting methods – both manual and mechanical, how coal is transported out of the coal mine, why the tunnel does not collapse after the excavation of coal, what are the safety measures adopted etc.
