Hindustan Zinc Limited Case study

Enabling digitization of India’s Largest underground mine

Hindustan Zinc Limited’s Sindesar Khurd Mines

Lean operations, safe environments, and efficiency are essential for the mining industry. Managing equipment and assets and protecting employees is challenging in a mine because assets and employees are spread out and disconnected.

Cisco Connected Mining architecture provides secure and scalable network infrastructure, and lays the foundation to deliver real-time visibility and control across the mine. The overall goal is to ensure safe and efficient operations.
