Mine Development

Rajpura Dariba Mine (RDM), established in 1983, is strategically situated in Rajpura Dariba, Rajasthan, and has mature underground operations supported by best-in-class technology, automation, and operational practices. Certified ISO 9001, ISO 14001, ISO 45001, and ISO 50001, the mine is expanding its operations and infrastructure while strengthening technological leadership, sustainability initiatives, and safety standards.

Operational and Strategic Developments

Ramping productivity and throughput

  • Commissioned India’s first diesel-electric loader, 17 tonne capacity CAT-R2900XE
  • Completed new Maa Annapurna Portal for a larger cross-section decline and started decline development from underground and surface, enabling the introduction of higher capacity fleet like 65 MT low-profile dump trucks (LPDTs) and 21 MT load-haul-dump (LHD) vehicles
  • Implemented top-down mining method with paste fill, unlocking high-grade blocks in Main and East Lodes
  • Completed paste fill reticulation in the newly commissioned E4 block of East Lode

Technology and digital integration

  • Installed 28 Machine Max sensors for LPDTs and LHDs idle hour tracking and an Infinite Uptime sensor on the cage and skip winder for real-time data monitoring
  • Installed internet of things (IoT) sensors for 11 critical equipment items for 24/7 monitoring across the rod mill, ball mill, blowers, ventilation fan, and the filter feed tank agitator in the paste fill plant

Safety and environmental developments

  • Generated the highest-ever filtered tailings of 1.59 Mnt
  • Commissioned the following:
    • Tele-remote SIMBA drilling machines, enabling smoke hour drilling
    • Dust extraction (DE) system at the secondary crusher to improve air quality
    • 1 MVA dry-type transformer with an automatic fire detection and suppression system for main shaft winders
    • High-capacity pumps at 11 mRL with remote operation from surface, enabling unmanned pumping operation
  • Integrated a 360° AI-based motion detection camera into the MT42 LPDT to prevent man-machine interaction risks
  • Established an underground occupational health centre at -157 mRL and a rest shelter at 300 mRL
  • Installed motion sensor at 100 mRL grizzly for traffic control system and launched radio frequency identification (RFID) based collision awareness system

In FY2026, Rajpura Dariba Mine achieved record ore production from ramp of 443 kt, and Rajpura Dariba Mill achieved record milling recoveries, the highest-ever mined metal, and the best-ever grade of lead concentrate and silver content in lead concentrate.

Enabling Hindustan Zinc’s 2x Growth Plan

Actions planned

  • Deploying automation technologies, such as tele-remote drilling and automated/remote pumping
  • Deploying a higher capacity fleet: 42 MT dump trucks, M2D development drills, and tele-remote SIMBAs for drilling
  • Developing decline for East and South Lode mining (mining partner mobilised)
  • Developing a next-generation material handing mechanism to achieve 6.0 Mtpa ore production
  • Boosting operational efficiency, strengthening safety protocols, and optimising resource utilisation through predictive maintenance systems
6.0 Mtpa

Targeted ore production capacity by FY2029, up from 2.0 Mtpa
