Underground hard-rock mining - Wikipedia
Underground hard-rock mining refers to various underground mining techniques used to excavate "hard" minerals, usually those containing metals, such as ore containing gold, silver, iron, copper, zinc, nickel, tin, and lead. It also involves the same techniques used to excavate ores of gems, such as diamonds and rubies. Soft-rock mining refers to the excavation of softer minerals, such as salt, coal, a

The underground mining method is sublevel stoping (paste backfill) to extract ore from the Santo Niño, Cerro Colorado and Oberon de Weber deposits. The shaft project for hoisting underground ore was completed in mid-June 2016, increasing the planned capacity of the underground mine to 4,500 tonnes/day.

Chuquicamata Underground Mine - Hatch Ltd
Ore reserves of nearly 1760 million tonnes of copper and molybdenum have been quantified for the underground mine, representing more than 60% of the amount exploited from the mine in the last 90 years. The Chuquicamata underground mine will be designed with the highest safety standards in the mining industry worldwide.

Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and the depths involved. For example, if the ore is very high grade or carries a high price, then a higher cost method can be used.

The Environmental Problems Caused by Mining Earth.Org
The infrastructure created by mining operations in remote, untouched landscapes can lead to improved access to these regions which may result in further human-caused disturbance to the local ecological systems. The impact of mining operations on the surrounding land is also closely linked to the ecological setting of the mining sites.

Digging deeper: Mining methods explained Anglo American
The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
