  4. about 1 2 3 4 Limited shallow depth reserves amenable to opencast mining are likely to be exhausted in foreseeable future (20-25 years) and the production from opencast coal mines may reach a plateau. The resulting shortfall in production due to exhaustion/closure of open cast mine cannot be made up by conventional underground mining As gestation period is generally more in case of underground projects, hence we have to start our planning well in advance. Huge land requirement, Rehabilitation, re-settlement is huge social challenge. ESG compliance getting tougher day by day technology trend need of hour success story compariso n

  19. AIDA Sales VENTILATION ON DEMAND Ventilation on demand (VoD) systems employ sensors around the mine that transmit real-time data on key parameters such as equipment in use, personnel, and information from gas, flow, and temperature sensors to a central control system, enabling mine-wide control of fans and air regulators. Mine is equipped with automated regulators. VoD systems learn and adapt over time with more data available, intelligently adjusting and optimizing air flow to maximize air quality and minimize consumption. In addition, potential problems are identified more quickly and blast gases are evacuated faster, decreasing downtime. By controlling mine ventilation in this way, annual energy savings of up to 50% are possible.
