The Role of Excavators in Mining Operations

Hello, I’m Lisa, a project manager at a mining company. We’ve been deliberating on optimizing our operations and excavators come up often in discussions. I understand they’re crucial, but could someone shed more light on the specific role of excavators in mining? What tasks are they primarily responsible for? How significant is their contribution to the efficiency and productivity of a mining operation? I’d appreciate any insights from those knowledgeable in this area. Thanks!
