Any Heavy haul operators with mining experience?

If anyone is interested in help a lady out... I need to fill out a career research page. I need 2 heavy haul operators with mining experience to answer these questions...I would really apperciate any input

example...Hours of Work (shifts, weekends, overtime, availability)..
Places of Work (environment, sectors, location accessibility, paperwork/academics, workplace expectations)
Physical Expectations (strength, daily tasks, fitness level, challenges to expect)
Occupational Health & Safety Considerations (health risks, workplace hazards, long term effects, work/life balance)

There is a a couple other questions too.. I know its a lot but its part of my application and it would be mighty neighbourly!:cowboy

Feel free to pm me with your list of questions. I just got laid off from a mine in northern BC when it closed so I have a bit of free time. I can answer them over the next couple of days. I've driven hauls trucks of various sizes, run dozer, grader, wheel loader and large excavator.
