upon further thought the same safety rules for miner would still apply for machines. methane pockets are still a danger due to coal fires and I very much doubt those machines can handle cave ins.

peole have a bad habit of thinking machines are tougher than people.

Machines are tougher than people in some ways. You can make a machine out of steel. It all dependson how your design the machine.

It is not now possible to make a mining machine as smart as a miner. Someday, this will no longer be the case.

toughness is a cost factor

ex. your stereo system can be design to be placed in front of the heeater but the cost would likely make people buy the unit with the tag don`t put near heated areas.

note how few people buy the toughbook laptop. there`s a demand but the cost  really weens out the purchases.
