During FY 2023-24, we made significant strides in augmenting the productivity and efficiency at RDM. We delivered strong numbers across the key metrics of our performance at the back of our focussed initiatives.

Our hydro-fill plant had a lower flow rate of 70 m3/hour. It also required addition of water to fill mixture, at 60:40 solid-to-water ratio. The year-on-year production growth was leading to an increase in the requirement for backfill. To meet the enhanced production requirements and improve the flow, we commissioned 1.8 Mtpa paste-fill plant during the year.
At Hindustan Zinc, our focus is on unlocking endless possibilities and fostering sustainable growth through digitalisation. Our pioneering spirit empowers us to embrace cutting-edge innovations, such as underground battery electric vehicles, realtime equipment monitoring and tele remote solo drilling. These initiatives not only make the mining operations smarter and safer but also contribute to the well-being of our employees, business partners and the entire ecosystem.
To enhance the operational efficiency at RDM, we undertook various measures during FY 2023-24 to optimise the equipment used in underground (UG) mining. These initiatives included:
I. Replacement of the double piece jaw plate with a single piece jaw plate in the underground crusher, and
II. Conversion of actuator system to cylinder system in the underground drilling machines
The first initiative was aimed at improving the life of the jaw crusher plate, which was reduced by frequent loosening of the centre wedge after 180 kt of crushing. The other initiative was aimed at countering the frequent breakdown of the drilling machine due to gripper arm misalignment, caused by damaged actuation system. The new cylinder system is easier to maintain and replace, in the event of total damage or overhaul.
