Tata Steel Jharia division mines are operating mines of more than 100 years of legacy. The working is Jharia coalfield are in multi seam from seam 18 to seam 0 in various part of the coalfield. The mining spans from early 20's to 21st century. The mining method has gone under tremendous change and thus is evident from the various technologies used in this division of Tata steel. It has seen many successes and many failures in the century old life. The mines are still an active field for technology innovation and adoption from world best practices. The underground mines in this division are filled with many old workings whose even record is difficult to find. The workings are filled with water. The seams are gassy and evidently there is fire in seams. The safety in the mines is of paramount concern, but with the coal prices touching sky highs it is also of great importance to extract the coal in safe and productive manner. Tata Steel being a steel producer needs coal at lowest cost for maintaining the cost advantage over competitors. The coking coal supply is ensured from Jharia division of Tata Steel. It has five underground mines which are degree 2 or degree 3 mines. This paper deals with the various initiative and innovation. Tata Steel underground mines division is taking to improve safety and productivity.
