The following sections delve into the current status and issues related to SMs in various areas of mining, including open-pit mining, deep underground mining, underground green mining of complex and challenging mining bodies, integrated underground mining and processing, and intelligent mining. 3.1. Open-pit mining3.1.1.
Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.
Owen [47] notes that diesel-powered construction equipment, such as dozers, wheel loaders, and excavators, release an estimated 400 million tons of CO 2 annually, making up 1.1% of global carbon emissions. An astounding 46% of these emissions are produced by excavators in the 10 t-plus categories, with the mining …
The exploitation of open pit deposits usually takes place through a series of mining phases, commonly known as pushbacks. In open pit metalliferous mining, each pushback considers the extraction of one or more benches simultaneously in a process where the core operational tasks include: drilling, blasting, loading and hauling.
The open pit mining industry is a pillar of the global economy, yet it faces challenges in terms of safety, operational efficiency and environmental impact.
