Design of an Effective Ventilation System for Deep Underground Coal
Few researchers successfully applied single booster fans in deep underground coal mines with multi-seam workings of Jharia coalfield (Mishra et al. 2022). There is no case study available on the application of a double booster fan in any Indian deep coal mines for improvement of the workplace environment with multi-seam workings.
