3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.

The top 5 most common hazards that cause injuries at a surface mine are: Handling Material. Slips, Trips, and Falls. Hand Tools. Powered Haulage. Machinery. The information in this article is primarily based on the most recent 2018 fatality and injury data published in the Department of Labor's Mine Injury and Worktime, Quarterly.
Worldwide mining operations are as much as 28 percent less productive today than a decade ago, according to new McKinsey research. The results from McKinsey's new MineLens Productivity Index (MPI), which adjusts for declining ore grades and mine cost inflation, show that the pronounced decline in productivity is evident …
2. The many ways mining activities impact biodiversity. Mining affects biodiversity at multiple spatial scales (site, landscape, regional and global) through direct (i.e. mineral extraction) and indirect processes (via industries supporting mining operations, and external stakeholders who gain access to biodiversity-rich areas as the result of …
To start with, the cutting machine has to cut into the face after each slice is taken to line itself up to cut the next web. It is incapable of cutting at right angles to the face, so has to be eased in at an angle. This is achieved by "snaking" the AFC on which the shearer travels, so that the cutter drum can cut a wedge shaped section of coal ...
