Analyzing Characteristics of Particulate Matter Pollution in Open-Pit
The particulate pollution in the open-pit coal mines of China is particularly severe in winter. The aim of this study is to understand the pollution characteristics of particulate matter (PM) in winter and provide a basis for the prevention and control of particulate pollution. We took the problem of PM concentration at the bottom of the …
Open-Pit Mining: A Comprehensive Guide
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.
Reclamation of Degraded Landscapes due to Opencast Mining
The most common surface mining methods such as strip mining, open pit mining, opencast mining and quarrying start from the earth's surface and keep exposure to the surface during the extraction period. Disruption of the surface significantly affects the soil, fauna, flora and surface water, thereby influencing all types of land use.
