1.1 PHASES OF A MINING PROJECT - ELAW
2019-2-4 descriptions of the most common methods. 1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit

Mining industry and sustainable development: time for ...
2017-6-9 The common mining practice until very recently could be summarized in a few steps: from obtaining a license, dig the ore, sell the metal, and, once the deposit was exhausted, walk-away and start another mine elsewhere (Jain et al. 2016; EB 2017). Not surprisingly, mining is among the human activities with widest environmental and social impacts.

ICMM Operating mines
Operating mines. Mining and metal production has evolved from being manual, unsafe, dirty and small-scale to being partially- or fully-automated, safer, cleaner and large-scale. Unlike their predecessors, today’s workers are highly trained personnel performing skilled work in accordance with the highest health, safety and environmental standards.

Open Pit Mining - an overview ScienceDirect Topics
Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground mining and ISL methods may be considered for sites that have uranium ores at deeper depths.
