Extraction Design of Locked-up Coal by Highwaii Mining in India

摘要

The CSIR-Central Institute of Mining and Fuel Research (CSIR-CIMFR), Dhanbad has provided the scientific extraction design for the complex Indian geomining conditions existing at the three Highwaii Mining sites at Ramagundem Opencast Project-ll and Medapalli OCP of M/s Singareni Collieries Company Ltd (SCCL), and Quarry SEB andAB, West Bokaro of M/s Tata Steel Ltd. (TSL). This made over 5 Million tonne of locked-up coal immediately viable for extraction by Highwaii Mining, thus adding to the fuel basket/inventory energy supply of the nation. The developed technology is so comprehensive that it is adaptable to virtually any situation existing in Indian coalfields. The present paper gives the scientific elucidation of the design technology adopted by CSIR-CIMFR.
