They back up a little too close to the edge where they are dumping, and it gives away. Happens more often than you would think but nearly always with inexperienced drivers

I had this happen with a dog in my photographic studio last week:



It took three of us and a 1-ton comealong to right the poor thing.

Well, that makes sense. Quite an expensive mistake.

Well, that makes sense. Quite an expensive mistake.

Mining operations are both expensive and dangerous. the larger the operation the bigger the equipment the greater the chance of an OOPs happening.
Different mining operations have different problems,
All surface, strip and pit mining have to first remove what is called the overburden, which can consist of several layers of dirt and rock they are not wanting.\
First if there is any topsoil this will have to be hauled away and mounded up separately for future reclamations. Then they may have layers of clay or gravel or other strata's they don't want before getting to the pay layer. Coal is one of the easier things to distinguish it is just stripped away and loaded, but minerals will have to be separated as best as can be done on site before the richer ores are sent off for processing.
All of this requires a place to pile up what is left over and when dealing with several thousand tons per day or even per hour packing it down as the mounds get ever higher can never be as well compacted as it was before being dug up. Trucks and dozers are the things that can wind up rolling downhill like a snowball headed for hell.
