Sometimes larger features and patterns (areas where miners removed a lot of brush, for example) cannot be seen from ground level, but are obvious from far up in the sky. This is also a good way to get an idea of the condition of the roads in the area so you'll know in advance which look to be commonly traveled. Google Earth ties in with GPS, too.

As findings indicate in (Table 3) that overall impacts of the mining operations the dehydration of the brook (10.6%), soil erosion (20.8%), and damage of the street (17.6%) are major consequences of the mining operations in study area. Extracting gemstones and gold mining negatively affects the environment through destruction of …

Gold mining has serious negative environmental impacts, especially due to pollution emanating from tailings storage facilities (TSFs, tailings dams, slimes dams). The most important forms of pollution from TSFs are acid mine drainage (AMD) and high levels of potentially toxic elements (PTEs). AMD arises from the high levels of pyrite in the …

The South African Human Rights Commission estimates that there are between 8000 and 30 000 illegal miners operating in South Africa.

Mining - Prospecting, Exploration, Resources: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, …

Similarly, Lobo et al. (2018) effectively mapped mining areas in the Brazilian Amazon using Sentinel-2 images, highlighting the prevalence of small-scale gold and tin mining. Another study in the Peruvian Amazon by Espejo et al. (2018) illustrated the ecological consequences of gold mining on deforestation and forest degradation, …
