2021.7.31 The variety of equipment may overwhelm the student. Certain machines dominate the scene, however, and they are easily learned. For surface mining, shovels, loaders, draglines, and scrapers are in most common use. For underground mining, loaders load-haul-dump units (LHD5), and continuous miners are prevalent.

2021.7.31 8.1 Surface Mining Methods. Surface mining deposits can be primarily divided as follows: Relatively horizontally stratified deposits with thick or thin overburden. Stratified and vein deposits dipping at angles; greater than the angle of repose of the spoil so that overburden cannot be deposited within the pit.

2019.7.9 Mining continues to be a dangerous activity, whether large-scale industrial mining or small-scale artisanal mining. Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners. I look at mining and health from various
