Mine Development
Commissioned in 2011 and located in Ajmer, Rajasthan, Kayad is one of India’s most recognised underground (UG) zinc-lead mines for safety, sustainability and operational excellence. This ISO 9001, 14001, 45001, and 50001 certified mine has been recognised with the prestigious Indian Bureau of Mines (IBM) 5-Star Rating nine times and holds a GreenCo Silver Rating from CII - Sohrabji Godrej Green Business Centre.
Operational & Strategic Developments
Ramping productivity and throughput
- Commissioned two fans parallelly, one of 132 kW at +250 mRL and other of 450 kW at +120 mRL, boosting airflow by 150 m3/sec and enabling efficient operations in deeper levels
- Reduced the level interval of K21 Lens from 20m to 15m to control hang wall failure, reducing dilution and improving stope recovery
- Transitioned from longitudinal to transversal mining method through a combination of uphole and downhole methods, which eliminated footwall drives, enhancing ore recovery and resulting in cost savings
- Improved stope design through detailed, fast-track exploration from drilling drives to delineate ore-bodies and optimise extraction drive placement
- Deployed Machine Max software to reduce idle time of low-profile dump trucks (LPDTs), enabling rapid project execution through smart resource optimisation
Safety and environmental developments
- Commissioned the first EV loader for ore hauling, reducing annual Scope 1 emissions by c.135 tCO2e
- Unlocked ventilation in the lower section through the highest-ever raise boring drilling of 791m
- Installed three man-passes in mines, eliminating the secondary outlet
Kayad Mine got certified as a 10x water positive unit by Det Norsk Veritas
Enabling Hindustan Zinc’s 2x Growth Plan
Actions planned
- Accelerating exploration in the S22 lens
- Increasing mine development in new areas
- Deploying more automated or advanced vehicles to expedite turnaround time and increase ore production rates
1.5 Mtpa
Targeted ore production capacity by FY2030, up from 1.0 Mtpa
